Production experience builds judgment about trade-offs, operational concerns, and safe deployment practices. - ---- - -## Key Design Decisions - -### 1. Sequential Phases Over Topic Organization - -**Decision**: Organize specs by learning progression (Foundation → Topics → Production) rather than by topic similarity. - -**Rationale**: -- Students need to understand applications before building them -- Core topics (DB, API, Auth) should be learned before production scenarios -- Production work synthesizes all previous learning -- Clear progression shows students their growth - -### 2. Integrate SDD Into Production Exercises - -**Decision**: Teach Spec-Driven Development through doing, starting in Spec 06 (Debugging & Observability). - -**Rationale**: -- Learning by doing is more effective than abstract instruction -- Students see the value when applying SDD to real production scenarios -- Timing aligns with complexity that benefits from structured workflows -- Avoids front-loading methodology before students understand the problems it solves - -### 3. Select Core Topics, Defer Advanced Topics - -**Decision**: Include Databases, REST APIs, and Authentication in initial specs. Defer frontend patterns, additional backend patterns, and advanced topics. - -**Rationale**: -- These three topics are universal in production applications -- Limited time requires prioritization -- Can add deferred topics based on student feedback and needs -- Avoids overwhelming students with too many concepts - -### 4. Infrastructure Requirements Over Implementation - -**Decision**: Specs define what infrastructure is needed (dev/prod environments, monitoring) but defer specific implementation decisions to task planning. - -**Rationale**: -- Separates "what" from "how" -- Allows flexibility in implementation approach -- Can adapt to available resources and technologies -- Spec remains stable while implementation can evolve - -### 5. Multi-Language Examples - -**Decision**: Distribute code examples across Python, Go, and TypeScript based on pedagogical fit. - -**Rationale**: -- Exposes students to multiple paradigms -- Matches language to pattern strengths (e.g., Go for interfaces, TypeScript for type safety) -- Prepares students for polyglot professional environments -- Existing chapter uses Python primarily, providing continuity - -### 6. Use OTel Demo App for Production Exercises - -**Decision**: Base production exercises (Spec 06-07) on OpenTelemetry Demo Application or similar. - -**Rationale**: -- Already includes full observability instrumentation -- Realistic microservice architecture -- Well-documented with known exercises -- Active community support -- Students can continue exploration independently -

Recommended for keeping the focus on KEDA rather than the queue itself. -- [ ] (B) **RabbitMQ** — More realistic for e-commerce. Richer KEDA scaler (messages ready in queue). Adds ~1 Helm chart dependency and a bit more config overhead. -- [ ] (C) **NATS JetStream** — Lightweight and modern, but less familiar to most bootcamp students. -- [ ] (D) Other (describe) - -## 2. Application Language - -Which language for `checkout-service` and `order-processor`? This affects how approachable the code is for students who may read it. - -- [x] (A) **Go** — Fast startup, single binary, tiny Docker images, idiomatic for Kubernetes tooling. Slightly higher barrier if students aren't Go-familiar, but the code will be short enough that language isn't a blocker. Recommended. -- [ ] (B) **Python** — Very readable for beginners, familiar to most. Slightly heavier images and slower startup than Go. -- [ ] (C) **Node.js** — Familiar to many, async-friendly for the HTTP layer. -- [ ] (D) Other (describe) - -## 3. Load Generator - -How should the flash sale simulation be run? This is what students trigger in Exercises 2, 3, and 6 to observe queue buildup. - -- [ ] (A) **Shell script (`load/run.sh`)** — Uses `curl` in a loop with configurable concurrency (e.g., `xargs` or background jobs). Zero extra dependencies. Students can read and understand it easily. -- [x] (B) **k6 script** — Industry-standard load testing tool, great learning artifact. Adds one CLI dependency (`k6`). -- [ ] (C) **`hey` one-liner** — Single binary, clean output. One extra install but minimal. -- [ ] (D) Other (describe) - -## 4. Simulated Processing Delay - -The `order-processor` needs to do "fake" CPU-bound work so the queue backs up visibly under load. How should this be simulated? - -- [ ] (A) **Fixed sleep (e.g., 500ms per order)** — Simple and predictable. Queue depth becomes purely a function of arrival rate vs. worker count. Easy to reason about for students. -- [ ] (B) **Sleep + tight CPU loop (math/hashing)** — More realistic CPU spike that makes the HPA exercise (Exercise 3) more convincing. Slightly harder to tune. -- [x] (C) **Configurable via env var** — Let the sleep/work duration be set at deploy time so instructors can tune the demo without rebuilding images. -- [ ] (D) Other (describe) - -## 5. Reference ScaledObject - -In Exercise 5, students write the ScaledObject themselves. Should the repo include a reference solution? - -- [ ] (A) **Yes, in a `solutions/` subdirectory** — Students can check their work. Instructors can use it to reset state between cohorts. -- [ ] (B) **Yes, but commented out in the main manifests** — Lower friction, but risks students skipping the exercise. -- [x] (C) **No reference solution** — Students must figure it out from the KEDA docs. More authentic discovery, but could create frustrating dead ends. -- [ ] (D) Other (describe) - -## 6. Kustomize Structure - -How should the Kubernetes manifests be organized? - -- [ ] (A) **Base only** — Single set of manifests in `k8s/base/`. Simple, no overlays. Good for a learning example where there's only one target environment (local k3d). -- [x] (B) **Base + `local` overlay** — Follows Kustomize best practices more closely. Slightly more files but teaches the pattern students will see in real projects. -- [ ] (C) Other (describe) - -## 7. Sidebar / Navigation - -The existing bootcamp sidebar at `docs/_sidebar.md` will need an entry for the new `9.6-keda.md` page. Should we also update the HPA page (`9.5-hpas.md`) to link forward to this new exercise as a "next steps" or "what's next" pointer? - -- [ ] (A) **Yes** — Add a brief forward reference at the bottom of 9.5-hpas.md pointing to the KEDA exercise. -- [ ] (B) **No** — Keep the pages self-contained; the sidebar is sufficient navigation. -- [x] (C) Other (describe) Yes to (A), we will also need to increment all subsequent 9.* sections by 1. diff --git a/docs/specs/01-spec-keda-exercise/01-spec-keda-exercise.md b/docs/specs/01-spec-keda-exercise/01-spec-keda-exercise.md deleted file mode 100644 index 4e0b6ea4..00000000 --- a/docs/specs/01-spec-keda-exercise/01-spec-keda-exercise.md +++ /dev/null @@ -1,188 +0,0 @@ -# 01-spec-keda-exercise.md - -## Introduction / Overview - -This spec covers the design and implementation of a companion example application and a new bootcamp exercise page for Chapter 9. The example is a minimal faux e-commerce order processing system built around a producer/consumer pattern: a `checkout-service` enqueues orders into Redis, and an `order-processor` consumes them. The system exists to expose a concrete failure mode — queue depth growing faster than a CPU-triggered HPA can react — and to demonstrate how KEDA resolves it by scaling on the queue depth itself. - -The deliverable is two things: (1) a self-contained, Taskfile-driven example in `examples/ch9/keda/` deployable to a local k3d cluster, and (2) a new docs page `docs/9-kubernetes-container-orchestration/9.6-keda.md` structured as six progressive exercises. All existing docs pages currently numbered `9.6` and above must be renumbered `+1` and the sidebar updated accordingly. - ---- - -## Goals - -- Provide a working producer/consumer system that visibly degrades under flash-sale load without autoscaling. -- Demonstrate that a CPU-based HPA reacts too slowly to prevent queue buildup under a sudden surge. -- Demonstrate that a KEDA `ScaledObject` keyed on Redis list length scales the `order-processor` proactively, keeping the queue shallow under the same load. -- Keep application code simple enough that students can read and understand it in under five minutes — the architecture is the lesson, not the business logic. -- Produce a docs page that follows the established bootcamp exercise format (front-matter, H2 sections, step-by-step kubectl/task commands, deliverables). - ---- - -## User Stories - -**As a bootcamp student**, I want to deploy a working order processing system with a single command so that I can start the KEDA exercises without spending time on infrastructure setup. - -**As a bootcamp student**, I want to watch the system visibly fail under load and then visibly recover after applying KEDA so that the difference between a reactive (CPU-based) and a proactive (queue-depth-based) autoscaling signal is concrete and observable, not theoretical. - -**As a bootcamp student**, I want to write the `ScaledObject` myself by consulting the KEDA documentation so that I practice the skill of reading vendor docs and translating them into Kubernetes resources. - -**As a bootcamp instructor**, I want the example to be self-contained and driven by a Taskfile so that I can reset and re-run the demo between cohorts without memorizing a sequence of commands. - ---- - -## Demoable Units of Work - -### Unit 1: Core Application Stack Running in k3d - -**Purpose:** Both services and Redis are deployed to a local k3d cluster. A checkout request can be sent, the order message appears in Redis, and the order-processor consumes and logs it. The end-to-end data path works. - -**Functional Requirements:** -- The `checkout-service` shall expose a `POST /checkout` endpoint that accepts a JSON body with at minimum an `order_id` and `items` array, pushes a serialized message to a Redis list key (`orders:queue`), and returns `HTTP 202 Accepted`. -- The `order-processor` shall continuously pop messages from `orders:queue` using a blocking Redis pop, simulate work for a configurable duration (`PROCESS_DELAY_MS` env var, default `500`), and log the completed order ID. -- The simulated work shall include both a sleep and a small tight CPU loop so that sustained load produces both latency and measurable CPU pressure, making the HPA exercise believable. -- Both services shall read the Redis address from a `REDIS_ADDR` environment variable sourced from a Kubernetes Secret; no credentials shall be hardcoded in source code or container images. -- Both services shall be written in Go and produce minimal, single-stage Docker images using a multi-stage build (builder → `scratch` or `alpine`). -- The `deps:check` Taskfile task shall verify that k3d, Docker, Go, k6, and `watch` are installed, print the missing tool names and a brief installation hint for each, and exit non-zero if any are absent. -- The `cluster:create` Taskfile task shall create a k3d cluster named `keda-demo`. -- The `images:build` task shall build both Docker images. -- The `images:load` task shall import both images into the k3d cluster so no registry is required. -- The `deploy:all` task shall apply the full Kustomize stack (queue + app) in the correct order. - -**Proof Artifacts:** -- `kubectl get pods -n keda-demo` output showing `checkout-service`, `order-processor`, and `redis` pods all in `Running` state demonstrates the stack is up. -- `curl -s -X POST http://localhost:/checkout -d '{"order_id":"test-1","items":[{"sku":"ABC","qty":1}]}'` returning `202` demonstrates the checkout endpoint is live. -- `kubectl logs -n keda-demo deploy/order-processor` showing `completed order test-1` demonstrates the end-to-end flow. - ---- - -### Unit 2: k6 Flash Sale Load Test Demonstrating Failure Modes - -**Purpose:** A k6 script fires a configurable burst of checkout requests. Under baseline conditions (no autoscaling), the queue grows and order processing falls behind. After adding a CPU HPA, the system still degrades — just more slowly. Students observe both failure modes using `kubectl` commands. - -**Functional Requirements:** -- A `load/flash-sale.js` k6 script shall be included that sends concurrent `POST /checkout` requests at a rate and concurrency level sufficient to outpace a single `order-processor` replica within ~30 seconds. -- The script shall accept k6 environment variable overrides for `CHECKOUT_URL`, `VUS` (virtual users), and `DURATION` so instructors can tune load without editing the file. -- The `load:run` Taskfile task shall invoke k6 with default parameters that produce visible queue growth. -- The `observe` Taskfile task shall run a watch loop that prints, every 2 seconds: current Redis list length (`LLEN orders:queue`) and current `order-processor` pod count. This is the primary observable artifact for all three load test runs. -- A `k8s/base/hpa.yaml` manifest shall define a CPU-based HPA targeting the `order-processor` Deployment with min `1`, max `10`, and target CPU `50%`. Students apply this in Exercise 3 and delete it in Exercise 4. - -**Proof Artifacts:** -- Terminal output of `observe` task during Exercise 2 showing `queue depth` climbing (e.g., 50 → 200 → 500) with pod count stuck at `1` demonstrates the baseline failure. -- Terminal output of `observe` task during Exercise 3 showing pod count eventually increasing but queue depth still spiking before scale-out demonstrates the HPA lag. - ---- - -### Unit 3: KEDA ScaledObject — Queue-Depth-Based Scaling - -**Purpose:** Students install KEDA, write a `ScaledObject` themselves using the KEDA docs, apply it, and re-run the load test. The queue stays shallow and orders process without degradation. - -**Functional Requirements:** -- A `k8s/base/redis-secret.yaml` manifest shall provide the Redis connection string as a Kubernetes Secret that the KEDA `TriggerAuthentication` resource references; no credentials shall be hardcoded in the `ScaledObject` or application manifests. -- A `k8s/base/keda-trigger-auth.yaml` manifest shall define a `TriggerAuthentication` resource that reads Redis credentials from the Secret above. -- The `ScaledObject` targeting `order-processor` shall **not** be provided in the repo — students write it themselves, referencing the KEDA docs for the `redis-lists` scaler. -- The docs page shall include a description of every required field a valid `ScaledObject` must have for this setup (target deployment, scaler type, Redis list key, threshold, min/max replicas), without providing the YAML directly. -- The `deploy:all` task shall **not** apply the ScaledObject; students apply it manually as part of Exercise 5. -- After applying the student-written ScaledObject, `kubectl get scaledobject -n keda-demo` shall show `READY: True`. - -**Proof Artifacts:** -- `kubectl get scaledobject -n keda-demo` showing `READY: True` demonstrates KEDA accepted the student's ScaledObject. -- Terminal output of `observe` task during Exercise 6 showing queue depth staying below the scaling threshold (e.g., ≤ 5) while pod count grows demonstrates proactive scaling. -- Comparison of queue depth peaks across all three load test runs (Exercise 2: no autoscaling, Exercise 3: CPU HPA, Exercise 6: KEDA) makes the KEDA advantage visible. - ---- - -### Unit 4: Bootcamp Docs Page `9.6-keda.md` - -**Purpose:** A complete, publishable exercise page in the bootcamp's existing format that walks students through all six exercises using the example repo. Includes front-matter, intro, exercise sections, and deliverable questions. - -**Functional Requirements:** -- The docs page shall include YAML front-matter with `category: Container Orchestration`, `estReadingMinutes`, and an `exercises` array with six entries matching the structure of `9.5-hpas.md` (name, description, estMinutes, technologies). -- The page shall open with a 2–3 paragraph introduction explaining what KEDA is, why event-driven autoscaling matters, and how it differs from the HPA covered in the previous section. -- Each of the six exercises shall be an H2 section (`##`) with numbered steps, inline code blocks for all commands, and an observation prompt telling students what to look for. -- The page shall reference `examples/ch9/keda/` as the companion repo location, consistent with how `9.5-hpas.md` references `examples/ch9/hpas/`. -- The page shall close with a `### Deliverables` section containing the three reflection questions from Josh's spec. -- All existing docs pages currently at `9.6` and above shall be renumbered `+1` (filenames, front-matter, H1 titles, and sidebar entries). -- A forward-reference note shall be added at the bottom of `9.5-hpas.md` pointing to the new `9.6-keda.md` page. -- `docs/_sidebar.md` shall be updated to include `9.6-keda.md` and all renumbered entries. - -**Proof Artifacts:** -- `npm start` renders the new page at `/9-kubernetes-container-orchestration/9.6-keda` without 404 or broken sidebar links demonstrates the page is wired into the site. -- Front-matter validation passes (`npm run refresh-front-matter` exits 0) demonstrates metadata is well-formed. - ---- - -## Non-Goals (Out of Scope) - -1. **Cloud deployment or public exposure**: The example targets local k3d only. No Ingress, LoadBalancer services, DNS, or TLS. -2. **Persistent storage**: Orders are ephemeral. Redis runs without a PersistentVolume; data is lost on pod restart. This is intentional and acceptable for a demo. -3. **Service-to-service authentication**: No mTLS, API keys, or auth tokens between `checkout-service`, Redis, and `order-processor`. -4. **Monitoring dashboards**: No Prometheus, Grafana, or Loki. Observability is kubectl-native (`logs`, `get pods --watch`, `redis-cli llen`). -5. **Reference ScaledObject solution**: Students write the ScaledObject from scratch using KEDA docs. No solution file is provided. -6. **Production security hardening**: No Pod Security Standards enforcement, NetworkPolicies, or non-root user enforcement beyond what's trivially easy to include. -7. **Multiple Kustomize overlays beyond `local`**: Only a `base` and a `local` overlay. No `staging` or `prod`. - ---- - -## Design Considerations - -No UI. The "interface" students interact with is: -- `task ` invocations from the terminal -- `kubectl` commands for observation -- A text editor for writing the `ScaledObject` YAML -- k6 terminal output for load test results - -The docs page should use the same visual conventions as `9.5-hpas.md`: fenced code blocks for all commands, inline `code` spans for file paths and resource names, no diagrams required (but a simple ASCII flow diagram of `checkout-service → Redis list → order-processor` would be a nice addition if it fits naturally). - ---- - -## Repository Standards - -- **Exercise front-matter**: Must follow the YAML template established in `docs/README.md`. Reuse existing categories (`Container Orchestration`) and technologies (`Docker`, `Kubernetes`) rather than introducing new ones. Add `KEDA`, `Redis`, and `k6` only if they do not already exist in the master record; check `docs/README.md` before adding. -- **Example directory layout**: Follow the pattern of `examples/ch9/hpas/` — flat structure, no nested sub-repos, manifests in a dedicated subdirectory. -- **Commit hygiene**: Pre-commit hooks run `front-matter-condenser.js`. After adding the new page, run `npm run refresh-front-matter` before committing to avoid hook failures. -- **Markdown style**: H3 (`###`) as default within pages; H2 (`##`) for top-level exercise sections (these appear in the Docsify table of contents). Images in `/img/`, referenced with HTML `` tags. -- **Taskfile**: Use `task` (Taskfile v3 schema). Task names should use the `namespace:verb` convention (e.g., `cluster:create`, `images:build`). - ---- - -## Technical Considerations - -- **Redis scaler**: KEDA's `redis-lists` scaler uses `LLEN` on the target list key. The `ScaledObject` threshold represents the target number of messages per replica. With `PROCESS_DELAY_MS=500` (2 orders/sec/replica) and a threshold of `10`, KEDA will scale up when there are more than 10 unprocessed orders waiting. -- **k3d image loading**: Because k3d runs nodes inside Docker containers, images built locally must be loaded with `k3d image import` (wrapped in the `images:load` task). The `imagePullPolicy` in the Deployment manifests must be `Never` or `IfNotPresent` — set this in the `local` Kustomize overlay patch. -- **Checkout service exposure**: The `checkout-service` only needs to be reachable by k6 running on the host. Use `kubectl port-forward` (wrapped in a Taskfile task or documented as a prerequisite step) rather than a NodePort or LoadBalancer service. -- **KEDA installation**: Students install KEDA via Helm in Exercise 4. The docs page should pin a specific KEDA version (e.g., `2.16`) to avoid version drift between bootcamp cohorts. -- **HPA + KEDA conflict**: KEDA creates and manages its own HPA under the hood. If the student-created CPU HPA from Exercise 3 is not deleted before applying the ScaledObject, Kubernetes will have two HPAs targeting the same deployment. Exercise 4 must explicitly instruct students to delete the manual HPA before proceeding. -- **Processing delay tuning**: The default `PROCESS_DELAY_MS=500` combined with the default k6 load (e.g., 50 VUs for 60 seconds) should produce a peak queue depth of several hundred messages with one replica, making degradation unmistakable. This should be validated during development and the k6 defaults adjusted if needed. -- **Go modules**: Each service lives in its own subdirectory with its own `go.mod`. No shared module or workspace needed at this scope. - ---- - -## Security Considerations - -- **Redis credentials**: Redis will run without a password in the local k3d environment. The `REDIS_ADDR` env var (e.g., `redis:6379`) is not sensitive. A Kubernetes Secret is still used to source it (to teach the pattern), but the value itself is not secret. No password auth is configured on the Redis instance. -- **No hardcoded credentials**: Neither service's source code nor Dockerfile shall contain connection strings, passwords, or tokens. All configuration is injected via environment variables from Kubernetes Secrets or ConfigMaps. -- **Proof artifacts**: No sensitive data should appear in proof artifact screenshots or terminal dumps. Redis list contents may contain fake order payloads — these are not sensitive. - ---- - -## Success Metrics - -1. **End-to-end demo reproducibility**: A student following the exercise instructions on a clean macOS or Linux machine with k3d, Docker, Go, and k6 installed can complete all six exercises without undocumented steps. -2. **Visible failure mode**: During Exercise 2, `LLEN orders:queue` must reach at least `50` within 30 seconds of starting the load test with default parameters, making degradation unambiguous. -3. **Visible KEDA recovery**: During Exercise 6, `LLEN orders:queue` must stay below `20` throughout the same load test after a valid student-written ScaledObject is applied. -4. **Docs page integration**: `npm run refresh-front-matter` and `npm run lint` both exit `0` after adding the new page and renumbering existing ones. -5. **Student self-sufficiency on ScaledObject**: The docs page description of the required ScaledObject fields is complete enough that a student can write a valid one from the KEDA docs alone, without needing to ask for help. - ---- - -## Open Questions - -No open questions at this time. - ---- - -## Resolved Decisions - -1. **`deps:check` task**: Yes — the Taskfile shall include a `deps:check` task that verifies k3d, Docker, Go, k6, and `watch` are installed and prints installation hints for any that are missing. -2. **`observe` task implementation**: Use `watch -n2`.

-## Non-Goals (Out of Scope) - -1. **Code Implementation**: This section focuses on analysis and understanding, not building new services or modifying existing code. Implementation comes in later chapters. - -2. **Deep Observability Instrumentation**: While students will work with the OTel Demo Application, this section does not cover implementing observability. That is covered in 11.7 (Debugging & Observability). - -3. **Performance Analysis or Optimization**: Students will trace transactions to understand architecture, not to identify or fix performance bottlenecks. - -4. **Deployment or Infrastructure**: Setting up the OTel Demo Application is included, but deep dives into Kubernetes, cloud platforms, or infrastructure concerns are out of scope. - -5. **Specific Diagramming Tool Training**: Content introduces available tools but does not provide comprehensive tutorials for specific tools. Students choose and learn tools independently. - -6. **Front-End Architecture Deep Dive**: Analysis focuses on service-to-service interactions and system-level architecture, not front-end component design or state management patterns. - -## Design Considerations - -**Learning Materials Format:** -- Main content in `docs/11-application-development/11.3-system-thinking.md` following established chapter structure -- Use H2 headers for navigation (table of contents), H3 headers for content sections -- Include visual examples of all three diagram types using images in `docs/11-application-development/img11/` -- Use multi-column layouts (`grid2`, `grid3`) where appropriate for comparing diagram types or showing before/after examples - -**Example Application (Unit 1):** -- Create a simple 2-3 service application in `examples/ch11/simple-system/` -- Use Python (Flask) for consistency with previous chapter examples -- Include clear README, docker-compose.yml for easy setup -- Provide example diagrams in multiple formats (PlantUML source + rendered images) - -**OTel Demo Integration:** -- Link to official OTel Demo repository rather than duplicating code -- Provide bootcamp-specific setup guide in `examples/ch11/otel-demo-setup/` -- Create worked example diagrams and traces for the bootcamp repository -- Ensure version pinning for reproducibility - -**Templates and Rubrics:** -- Provide downloadable templates (ADR, README structure, presentation outline) in `examples/ch11/templates/` -- Include rubrics for self-assessment and instructor evaluation - -## Repository Standards - -**Content Organization:** -- Main documentation: `docs/11-application-development/11.3-system-thinking.md` -- Code examples: `examples/ch11/simple-system/`, `examples/ch11/otel-demo-setup/` -- Images: `docs/11-application-development/img11/` -- Templates: `examples/ch11/templates/` -

-**Example Standards:** -- All examples must be self-contained with README -- Use docker-compose for multi-service examples -- Pin all dependency versions -- Test on ARM-based macOS (M1/M2/M3) - -**Existing Patterns to Follow:** -- Hands-on, practical focus (like 11.1-layers.md exercises) -- Progressive complexity (like SOLID exercises in 11.2.1) -- Clear learning objectives and deliverables -- Interactive elements where appropriate (quizzes if beneficial) - -## Technical Considerations - -**OpenTelemetry Demo Application:** -- Use the official OTel Demo App (https://github.com/open-telemetry/opentelemetry-demo) -- Verify compatibility with ARM-based macOS -- Provide alternative setup methods (Docker Compose, Kubernetes) with Docker Compose as default -- Document minimum system requirements (RAM, CPU, disk) -- Pin to a specific release version for stability - -**Simple Example Application:** -- Keep it minimal: 2-3 services maximum -- Use familiar technologies: Python (Flask), SQLite -- Ensure it runs without external dependencies (no cloud APIs, no paid services) -- Make the architecture clear and easy to understand (intentionally simple, not production-realistic) - -**Diagramming Tools:** -- Recommend both code-based (PlantUML, Mermaid) and visual (Draw.io, Lucidchart) options -- Provide example diagrams in PlantUML format (can be rendered by Docsify plugins) -- Ensure students on free tiers can complete all exercises (no paid tool requirements) - -**Video Recording (for presentations):** -- Support multiple recording methods: Zoom, Loom, OBS, native OS tools -- Provide guidance on screen recording best practices -- Allow live presentations as alternative to recorded - -**Prerequisites:** -- Requires completion of 11.0-11.2 (layered architecture, design patterns, SOLID principles) -- Assumes Docker and container knowledge from earlier bootcamp chapters -- Assumes HTTP/REST API understanding from earlier chapters -- If gaps exist, provide quick refresher links - -## Security Considerations - -**OTel Demo Application:** -- The OTel Demo Application is designed for demonstration purposes and should only be run locally -- Students should not expose OTel Demo services to the public internet -- No real payment processing or sensitive data should be used with the demo application - -**Presentation Recordings:** -- Students should be informed if presentations will be shared publicly or kept private -- Ensure students do not accidentally share personal information (file paths with usernames, API keys in environment variables) when recording screens -- Provide guidance on sanitizing recordings before submission - -**Documentation and Diagrams:** -- Diagrams and documentation are safe to commit to repositories -- No secrets, credentials, or sensitive configuration should appear in documentation - -**No specific security implementations required in this section** - focus is on analysis, not building secure systems. - -## Success Metrics - -1. **Diagram Quality**: Students create accurate, clear diagrams that correctly represent system architecture. Diagrams are validated against actual code behavior and communication patterns. - -2. **Transaction Tracing Accuracy**: Students successfully trace complete transactions through multi-service architectures without missing service hops or misunderstanding communication patterns. - -3. **Documentation Clarity**: ADRs and README files are well-structured, clearly written, and provide useful architectural insights. Technical reviewers can understand the system from student documentation. - -4. **Presentation Effectiveness**: Student walkthroughs clearly explain architecture using diagrams, demonstrate understanding of trade-offs, and effectively communicate technical concepts. Target: 10-15 minute presentations covering all required topics. - -5. **Preparation for Later Chapters**: Students demonstrate sufficient understanding of the OTel Demo Application to successfully complete debugging exercises (11.7) and production development work (11.8). Target: 80%+ of students feel confident proceeding to production exercises. - -6. **Time Calibration**: Exercises align with estimated times (4-8 hours total). Target: 80%+ of students complete core exercises within estimated time ranges. - -7. **Student Confidence**: Self-assessment surveys show students feel significantly more confident analyzing unfamiliar codebases after completing this section. Target: 4+ on 5-point confidence scale. - -## Open Questions - -1. **OTel Demo Version**: Which specific version/release of the OpenTelemetry Demo Application should be pinned for this bootcamp? Need to verify stability and ARM compatibility. - -2. **Grading and Feedback**: Will student presentations be graded by instructors, self-assessed, or peer-reviewed? This affects rubric design and submission process. - -3. **Tool Recommendations**: While students have tool choice, should the bootcamp officially recommend specific tools (e.g., "we recommend starting with Mermaid or Draw.io")? This could reduce tool-selection paralysis. - -4. **Quiz Integration**: Should this section include an interactive quiz (like 11.2.1-solid-principles.md)? If yes, what concepts should be tested? - -5. **OTel Demo Simplification**: Should the bootcamp provide a "simplified subset" configuration of the OTel Demo (e.g., only 4-5 services enabled) to reduce complexity and system requirements, or use the full demo? - -6. **Live Presentation Logistics**: If students deliver live presentations, what is the format? One-on-one with instructor? Small groups? Recorded for async review? - -7. **Example Selection for Unit 2**: Which specific transaction/feature in the OTel Demo should be used for the worked example? Should align with student interests and demonstrate key concepts effectively. - -8. **Integration with Spec 01**: Should this section explicitly reference or build on design patterns from 11.2.2-11.2.5, or remain independent? diff --git a/docs/specs/02-spec-system-thinking/02-tasks-system-thinking.md b/docs/specs/02-spec-system-thinking/02-tasks-system-thinking.md deleted file mode 100644 index c1c4bc81..00000000 --- a/docs/specs/02-spec-system-thinking/02-tasks-system-thinking.md +++ /dev/null @@ -1,220 +0,0 @@ -# 02 Tasks -

estMinutes: 180 - technologies: - - SQL - - SQLAlchemy - - Repository Pattern - - Query Optimization ---- -``` - -**Style Guidelines:** -- Follow Docsify markdown conventions -- Use HTML `` tags for images with proper alt text -- Include code blocks with language-specific syntax highlighting -- Use callout boxes for important notes (performance tips, common pitfalls) - -**Example Standards:** -- All examples must be self-contained with README -- Use docker-compose for databases (PostgreSQL, Redis, document store) -- Pin all dependency versions in requirements.txt and pyproject.toml -- Test on ARM-based macOS (M1/M2/M3) -- Include .gitignore for *.db files, __pycache__, .venv/ - -**Existing Patterns to Follow:** -- Hands-on, practical focus (like 11.1-layers.md exercises) -- Progressive complexity (like SOLID exercises in 11.2.1) -- Clear learning objectives and deliverables -- Starting point codebases (like existing chapter 11 examples) - -## Technical Considerations - -**Database Selection:** -- **SQLite**: Primary database for exercises (file-based, no server, perfect for learning) -- **PostgreSQL**: Mentioned in examples as production alternative, used in docker-compose setups -- All SQLAlchemy examples should work with both databases without code changes (use database-agnostic features) - -**ORM Framework:** -- **SQLAlchemy 2.x**: Use modern SQLAlchemy with new-style declarative syntax -- Document both synchronous (default) and async options (mention only, don't require) -- Pin to SQLAlchemy 2.x in requirements (SQLAlchemy>=2.0,<3.0) - -**NoSQL Databases:** -- **Redis**: Use redis-py client library, docker image redis:7-alpine -- **Document Store**: MongoDB (docker image mongo:7) or alternative if preferred -- Provide docker-compose.yml for each so students don't need to install locally - -**Flask Integration:** -- Use Flask-SQLAlchemy extension for easier integration -- Show proper application factory pattern with SQLAlchemy initialization -- Demonstrate request lifecycle: session management, commit/rollback - -**Development Environment:** -- Python 3.11+ required -- Docker and Docker Compose for databases -- Recommended: VS Code with SQLite extension for viewing databases -- All examples tested on ARM-based macOS - -**Prerequisites:** -- Requires completion of 11.2 (especially 11.2.2 Data Layer Patterns) -- Assumes basic Python knowledge from earlier chapters -- Assumes Docker knowledge from earlier bootcamp chapters -- SQL knowledge helpful but not required (will be taught) - -## Security Considerations - -**SQL Injection Prevention:** -- All examples MUST use parameterized queries or ORM (never string concatenation for SQL) -- Explicitly warn about SQL injection with bad examples (commented as "DON'T DO THIS") -- Show proper parameter binding in raw SQL examples -- SQLAlchemy ORM is safe by default when used properly - -**Database Credentials:** -- Never commit database credentials to repositories -- Use environment variables for connection strings -- Provide .env.example files showing format without real credentials -- For exercises, use simple local credentials (e.g., "postgres"/"password") clearly labeled as "development only" - -**Data Privacy:** -- Exercise data should be fictional (no real names, emails, addresses) -- Warn students not to use personal information in database exercises -- No sensitive data in example applications (no passwords, payment info, SSNs) - -**NoSQL Security:** -- Redis in exercises should bind to localhost only (not exposed to network) -- Document stores should use basic authentication even in development -- Provide secure default configurations in docker-compose files - -**No production deployment**: Exercises are for local development only. Production deployment considerations (SSL, connection pooling, secrets management) are deferred to later sections. - -## Success Metrics - -1. **Schema Design Quality**: Students create properly normalized schemas (3NF) with appropriate relationships and constraints. Target: 80%+ of student schemas are normalized and use foreign keys correctly. - -2. **Repository Pattern Implementation**: Students successfully implement Repository pattern with SQLAlchemy, demonstrating clean separation between data access and business logic. Target: Working Repository implementations for all required entities. - -3. **Query Optimization Understanding**: Students can identify N+1 query problems, apply eager loading correctly, and add appropriate indexes. Target: 80%+ of students fix N+1 problems in provided codebase. - -4. **NoSQL Decision Making**: Students can articulate when to use SQL vs NoSQL and successfully implement caching with Redis. Target: 70%+ of students successfully add caching to application. - -5. **Working Applications**: All exercises result in working applications that can be run with `docker-compose up` and tested locally. Target: 90%+ success rate on running exercise codebases. - -6. **Time Calibration**: Exercises align with estimated times (11 hours total across 6 exercises). Target: 70%+ of students complete core exercises (Units 1-4) within estimated time. - -7. **Integration with Previous Sections**: Students explicitly connect this section to 11.2.2 Repository Pattern in their implementations. Target: Implementations reference pattern concepts from 11.2.2. - -8. **Student Confidence**: Post-section surveys show students feel confident designing schemas and implementing data access layers. Target: 4+ on 5-point confidence scale for "I can design a database schema" and "I can implement Repository pattern with an ORM." - -## Open Questions - -1. **Document Store Selection**: Should we use MongoDB (most popular, widely known) or alternative like CouchDB, RethinkDB, or even PostgreSQL's JSONB as a document store? MongoDB requires more resources but is industry standard. - -2. **SQLAlchemy Async**: Should we mention async SQLAlchemy patterns, or keep everything synchronous for simplicity? Async is increasingly common but adds complexity. - -3. **Database Migrations**: Should Unit 3 or 6 include basic Alembic usage for database migrations, or defer this entirely to later sections? Migrations are important but add scope. - -4. **Quiz Timing**: Should the interactive quiz come after Unit 4 (optimization) or at the end after Unit 6? Mid-chapter quizzes reinforce learning, end-of-chapter quizzes assess overall understanding. - -5. **PostgreSQL Depth**: How much should PostgreSQL-specific features be covered vs staying database-agnostic? Array types, JSONB, full-text search are powerful but not portable. - -6. **Unit 5 Second NoSQL Type**: For the document store example, should it be MongoDB (de facto standard), or leverage PostgreSQL JSONB (students already have PostgreSQL), or use a lighter option? - -7. **Integration Exercise Problem Domain**: What specific application domain for Unit 6 integration exercise? Blog platform, e-commerce, task management, social media clone? Should align with student interests and demonstrate realistic complexity. - -8. **Reference Material**: Should we provide links to external resources (SQLAlchemy docs, PostgreSQL tutorial, Redis guides) or keep everything self-contained in bootcamp? External links are valuable but can be overwhelming. diff --git a/docs/specs/98-spec-ai-engineering-modern-practices/98-proofs/98-task-01-proofs.md b/docs/specs/98-spec-ai-engineering-modern-practices/98-proofs/98-task-01-proofs.md deleted file mode 100644 index 457c931a..00000000 --- a/docs/specs/98-spec-ai-engineering-modern-practices/98-proofs/98-task-01-proofs.md +++ /dev/null @@ -1,145 +0,0 @@ -# Task 1.0 Proof Artifacts - Expand Context Engineering Coverage - -## Git Diff Summary - -The file `docs/3-AI-Engineering/3.1.4-ai-best-practices.md` has been significantly expanded with comprehensive context engineering coverage: - -- Updated front-matter: `estReadingMinutes` increased from 10 to 30 minutes -- Expanded "Don't depend on long lived chats" bullet into comprehensive explanation with WHY (context rot mechanism, 40%+ degradation zone) and HOW (intentional compaction techniques) -- Added 6 new H2 sections: - - Understanding Context Windows - - Context Rot and Performance Degradation - - Intentional Compaction Techniques - - Progressive Disclosure Patterns - - Tracking Context Utilization - - Resources and Further Reading -- Updated Deliverables section with 4 new context engineering questions - -## Documentation Review - New Sections Added - -### 1.

The update replaces the existing Harper Reed workflow with Liatrio's Spec-Driven Development (SDD) methodology (https://github.com/liatrio-labs/spec-driven-workflow) while integrating context engineering principles from HumanLayer's "No Vibes Allowed" methodology (https://www.youtube.com/watch?v=IS_y40zY-hc, https://www.youtube.com/watch?v=rmvDxxNubIg) and 12-Factor Agents framework. This modernization addresses critical gaps in the current documentation, including the absence of structured workflows, context management practices, and coverage of essential modern tools like Claude Code. The update transforms participants from "vibe-based" AI usage to disciplined, engineering-focused approaches that prevent common pitfalls like context rot and ensure reliable, maintainable AI-assisted development outcomes. - -## Goals - -1. **Replace informal workflows with SDD methodology** - Transform the existing Harper Reed workflow in 3.3.1-agentic-best-practices.md into a comprehensive, four-stage SDD workflow that guides beginners through structured AI-assisted development -2. **Establish context engineering as a core competency** - Significantly expand 3.1.4-ai-best-practices.md to include deep coverage of context windows, context rot, intentional compaction, and progressive disclosure techniques -3. **Modernize tool coverage with balanced AI assistant representation** - Maintain VSCode as the primary development environment while adding comprehensive Claude Code coverage alongside existing tools, giving equal attention to both VSCode-based AI capabilities and Claude Code -4. **Restructure exercises with SDD rigor** - Transform the "VSCode Vibing" exercise in 3.3.2-agentic-ide.md into an SDD-based exercise that guides participants through specification → task breakdown → implementation → validation -5. **Align documentation with beginner learning objectives** - Ensure all content serves developers new to AI-assisted development who need foundational knowledge and practical, structured workflows - -## User Stories - -**As a DevOps Bootcamp participant new to AI-assisted development**, I want to learn structured workflows for using AI tools so that I can avoid common pitfalls like context rot and produce reliable, maintainable code rather than experimenting with "vibe-based" approaches. - -**As a bootcamp instructor**, I want updated curriculum that reflects modern AI engineering practices so that I can teach students industry-relevant, professional workflows rather than outdated or informal methods. - -**As a developer using VSCode with AI assistants**, I want comprehensive documentation covering multiple AI tools (including Claude Code) with examples so that I can effectively leverage these tools using structured methodologies and understand how to manage context windows. - -**As a participant working through exercises**, I want clear guidance on the SDD workflow (spec → tasks → implementation → validation) so that I understand how to apply these practices to real-world development tasks. - -**As a beginner learning about AI limitations**, I want to understand context rot and how to prevent it so that I can maintain AI effectiveness throughout longer development sessions. - -## Demoable Units of Work -

-## Non-Goals (Out of Scope) - -1. **Creating entirely new chapter sections** - This update will not add new numbered sections (e.g., 3.4, 3.5) but will enhance and restructure existing content within the current chapter organization -2. **Coverage of advanced tools like CodeLayer or Cline** - Focus remains on Claude Code, Windsurf, and GitHub Copilot; advanced or emerging tools are excluded to maintain beginner-appropriate scope -3. **Dedicated 12-Factor Agents curriculum** - The 12-Factor Agents methodology will be mentioned in resources/further reading only, not taught comprehensively -4. **Requiring proof artifacts submission** - While proof artifacts will be introduced as best practices, participants will not be required to create or submit them for exercises -5. **Updating other bootcamp chapters** - Changes are strictly limited to Chapter 3 (AI Engineering); other chapters remain unchanged even if they could benefit from AI-related updates -6. **Creating entirely new quiz files** - While existing quiz content may be updated to reflect SDD and context management concepts, no entirely new quiz files will be created where none previously existed -7. **Changing repository documentation standards** - All updates must follow existing patterns; this is not an opportunity to evolve front-matter, exercise structure, or style guide conventions -8. **Creating new video tutorials or multimedia content** - No new videos or interactive media will be produced; however, existing YouTube videos (specifically https://www.youtube.com/watch?v=IS_y40zY-hc) will be embedded in the documentation -9. **Tool-specific installation guides** - Documentation will reference tools and their capabilities but will not provide detailed installation or setup instructions -10. **Integration with external SDD tooling** - While SDD methodology is taught, integration with external SDD tools or automation frameworks is out of scope - -## Design Considerations - -No specific design requirements identified. This update focuses on documentation content rather than visual design or UI elements. All visual components (images, diagrams) currently present in the chapter will be maintained unless they contradict updated methodologies. - -## Repository Standards - -All updates must follow the established repository patterns documented in CLAUDE.md and STYLE.md: - -**Content Standards:** -- Use H3 headers (`###`) as default within pages; H2 headers (`##`) for navigation/table of contents -- Images using HTML `` tags placed in `img/` or chapter-specific image directories (e.g., `img3/`) -- Front-matter YAML template with category, estReadingMinutes, and exercises metadata -- Deliverables sections at the end of each document with bulleted questions -- Quiz components embedded using `
` format -- YouTube videos embedded using Docsify video embedding plugin syntax (e.g., `[video](https://www.youtube.com/watch?v=VIDEO_ID)` or iframe embeds if supported) - -**Technical Standards:** -- Markdown files must pass `npm run lint` validation -- Front-matter must validate with `npm run refresh-front-matter` -- Exercise metadata must include name, description, estMinutes, and technologies array -- Multi-column layouts using `grid2`, `grid3`, `grid4` CSS classes where appropriate - -**Content Philosophy:** -- Minimize new categories and technologies in front-matter; reuse existing ones from master record (docs/README.md) -- Content should be accessible to bootcamp participants (clear, beginner-friendly language) -- Examples and exercises should be practical and directly applicable -- External links should be stable and authoritative sources - -**Version Control:** -- Changes will be committed following Docsify project conventions -- Pre-commit hooks (Husky) will validate front-matter automatically -- Commit messages should clearly describe what sections were updated and why - -## Technical Considerations - -**Markdown Processing:** -- All documentation uses Docsify for rendering; updates must be compatible with Docsify markdown parsing -- Code blocks should use appropriate syntax highlighting (e.g., ```text, ```yaml, ```markdown) -- Internal links use relative paths (e.g., `[3.3.1](3.3.1-agentic-best-practices.md)`) - -**Content Organization:** -- Updates span three primary documentation files: 3.1.4-ai-best-practices.md, 3.3.1-agentic-best-practices.md, 3.3.2-agentic-ide.md -- Updates include one quiz file: src/quizzes/chapter-3/3.3/agentic-best-practices-quiz.js (currently references Harper Reed workflow which will be replaced with SDD) -- Cross-references between sections must remain valid after updates -- Sidebar navigation (docs/_sidebar.md) remains unchanged as no new sections are added - -**Integration Points:** -- Context engineering concepts introduced in 3.1.4 must be referenced in 3.3.1 SDD workflow -- SDD workflow taught in 3.3.1 must be applied in 3.3.2 exercises -- Tool coverage (Claude Code) must be consistent across all mentions - -**Dependency Considerations:** -- No new npm dependencies or build tools required -- Existing linting and front-matter validation scripts must pass -- Changes should not affect webpack build process or Docsify serving - -## Security Considerations - -**Content Security:** -- Examples and exercises must avoid including actual API keys, credentials, or sensitive information -- Placeholders like `[YOUR_API_KEY_HERE]` or `[EXAMPLE_TOKEN]` should be used in all code examples -- Exercise instructions should remind participants not to commit real credentials - -**External Resources:** -- All linked resources (GitHub repositories, external documentation) should be from trusted sources -- Links to HumanLayer, Liatrio Labs, Anthropic, and other established organizations are appropriate -- Avoid linking to personal blogs or unverified sources for core methodology explanations - -**Tool Recommendations:** -- Recommended tools (VSCode with AI assistants, Claude Code, Windsurf, GitHub Copilot) should be mainstream, actively maintained projects -- Participants should be made aware of data privacy considerations when using AI tools -- Existing guidance on organizational policies regarding AI tool usage should be maintained and expanded - -**Proof Artifacts Guidance:** -- While proof artifacts are introduced as a concept, participants should be reminded to sanitize any screenshots or outputs that might contain sensitive information -- Exercise deliverables should emphasize learning outcomes over potentially sensitive proof evidence - -No specific security considerations identified beyond standard documentation best practices and maintaining existing bootcamp security guidance. - -## Success Metrics - -1. **Content Coverage Completeness** - All three primary files (3.1.4, 3.3.1, 3.3.2) and the quiz file (src/quizzes/chapter-3/3.3/agentic-best-practices-quiz.js) updated with SDD methodology, context engineering principles, and balanced tool coverage (VSCode as primary, Claude Code with equal attention) as specified in functional requirements -2. **Repository Standards Compliance** - All updated markdown files pass `npm run lint` validation and `npm run refresh-front-matter` succeeds without errors -3. **Learning Objective Alignment** - Updated content enables beginners to: understand fundamental AI concepts, apply structured workflows (SDD), manage context windows effectively, select appropriate tools, implement compaction/disclosure, build MCP servers, and work effectively with agentic IDEs -4. **Content Consistency** - Cross-references between sections remain valid, terminology is consistent, and content progression flows logically from foundations (3.1.4) through workflows (3.3.1) to application (3.3.2) -5. **Quiz Content Modernization** - Quiz questions updated to remove Harper Reed workflow references and include new questions on SDD methodology, context engineering, context rot, and intentional compaction -6. **Exercise Transformation** - "VSCode Vibing" exercise successfully restructured to follow complete SDD workflow (spec → tasks → implementation → validation) with context engineering practices integrated -7. **Outdated Content Removed** -

This rebranding reflects the expansion of content to include broader engineering topics while maintaining the core DevOps focus. The rename encompasses user-facing text, technical identifiers (package name, Docker images), and introductory content that frames the bootcamp in a broader engineering context. - -## Goals - -- Rebrand all user-facing elements from "DevOps Bootcamp" to "Liatrio Engineering Bootcamp" -- Update technical identifiers (package.json name, Docker image names) to reflect new branding -- Update introductory content to explain the broader "Engineering Bootcamp" concept while maintaining DevOps focus -- Create a GitHub issue documenting all repository URL references that need updating (after planned repository rename) -- Maintain content quality and accuracy - keep "DevOps" terminology where technically appropriate in chapter content - -## User Stories - -- **As a bootcamp user**, I want to see the updated "Liatrio Engineering Bootcamp" branding throughout the site so that I understand this is a comprehensive engineering resource, not just DevOps-specific. -- **As a developer**, I want consistent technical naming (package name, Docker images) so that I can easily identify and work with the updated project. -- **As a content maintainer**, I want clear documentation of all GitHub URL references that need updating so that I can coordinate the repository rename without missing any locations. -- **As a new user**, I want updated introductory content that explains the broader engineering scope so that I understand what topics are covered beyond traditional DevOps. - -## Demoable Units of Work - -### Unit 1: Update User-Facing Branding - -**Purpose:** Replace all visible "DevOps Bootcamp" text with "Liatrio Engineering Bootcamp" in user-facing elements (HTML, page titles, main navigation) while preserving "DevOps" where technically accurate in content. - -**Functional Requirements:** -- The system shall update the page title in index.html from "Liatrio's DevOps Bootcamp" to "Liatrio's Engineering Bootcamp" -- The system shall update the window.$docsify.name in index.html from "Liatrio's DevOps Bootcamp" to "Liatrio's Engineering Bootcamp" -- The system shall update the meta description in index.html to reference "Engineering Bootcamp" instead of "DevOps Bootcamp" -- The system shall preserve "DevOps" terminology in chapter content where it is technically accurate (e.g., "DevOps practices", "DevOps principles") -- The system shall update CLAUDE.md project overview from "Liatrio's DevOps Bootcamp" to "Liatrio's Engineering Bootcamp" - -**Proof Artifacts:** -- Screenshot: index.html rendered in browser showing "Liatrio's Engineering Bootcamp" in title and header demonstrates user-facing branding is updated -- Grep output: Search results showing remaining "DevOps" occurrences are only in appropriate technical contexts demonstrates selective replacement - -### Unit 2: Update Technical Identifiers - -**Purpose:** Update package.json name, description, and Docker-related naming from "devops-bootcamp" to "engineering-bootcamp" to align technical identifiers with the new branding. - -**Functional Requirements:** -- The system shall update package.json "name" field from "devops-bootcamp" to "engineering-bootcamp" -- The system shall update package.json "description" field to reference "Liatrio Engineering Bootcamp" -- The system shall update CLAUDE.md Docker commands from "devops-bootcamp" to "engineering-bootcamp" in all examples -- The system shall update CLAUDE.md development commands documentation to reference "Engineering Bootcamp" where appropriate -- The user shall be able to run `npm install` and `npm start` successfully after changes - -**Proof Artifacts:** -- CLI output: `cat package.json | grep -E '(name|description)'` shows updated fields demonstrates package metadata is updated -- CLI output: `npm install && npm start` runs successfully demonstrates package changes don't break functionality -- File content: CLAUDE.md showing updated Docker commands demonstrates documentation reflects new naming - -### Unit 3: Update Introductory Content - -**Purpose:** Revise introductory sections to explain the broader "Engineering Bootcamp" concept, framing DevOps content within a larger engineering context and acknowledging the expansion into software development topics. - -**Functional Requirements:** -- The system shall update the main docs/README.md or docs/1-introduction section to introduce "Liatrio Engineering Bootcamp" -- The content shall explain that the bootcamp covers engineering fundamentals with a focus on DevOps practices -- The content shall acknowledge the expansion into software development topics -- The content shall maintain existing learning paths and chapter structure -- The updated content shall be clear to both new users and existing users familiar with the previous "DevOps Bootcamp" branding - -**Proof Artifacts:** -- File content: Updated introduction section demonstrates new framing and explanation -- Review: Content review confirms messaging is clear and accurately represents the bootcamp scope - -### Unit 4: Document GitHub URL References - -**Purpose:** Create a comprehensive GitHub issue documenting all locations where `github.com/liatrio/devops-bootcamp` URLs appear, to be updated after the repository rename to `liatrio/engineering-bootcamp`. - -**Functional Requirements:** -- The system shall use a sub-agent to search the entire codebase for all occurrences of `github.com/liatrio/devops-bootcamp` -- The system shall enumerate all file paths and line numbers where repository URLs appear -- The system shall categorize findings by file type (e.g., configuration files, documentation, code examples, package.json) -- The system shall create a GitHub issue using `gh` CLI with a complete list of locations to update -- The issue shall include context that these URLs will be updated after the repository is renamed to `liatrio/engineering-bootcamp` -- The issue shall provide clear action items for updating each reference - -**Proof Artifacts:** -- GitHub issue: Created issue shows comprehensive list of all repository URL references with file paths and context demonstrates complete enumeration -- CLI output: `gh issue view ` displays the created issue demonstrates issue was successfully created - -## Non-Goals (Out of Scope) - -1. **GitHub repository rename**: The actual GitHub repository rename from `liatrio/devops-bootcamp` to `liatrio/engineering-bootcamp` is handled separately by the user -2. **Domain cutover**: The domain change from devops-bootcamp.liatr.io to engineering-bootcamp.liatr.io is handled separately by the user -3. **Updating GitHub URLs in code**: Repository URL references will be documented in a GitHub issue but not updated in this spec (deferred until after repository rename) -4. **Content restructuring**: No changes to chapter organization, learning paths, or content structure beyond introductory sections -5. **Comprehensive DevOps terminology replacement**: "DevOps" remains in chapter content where technically appropriate; only branding/title references are changed -6. **README.md updates**: The root README.md file changes are minimal/not in scope for user-facing branding (primarily development docs) - -## Design Considerations - -No specific design requirements identified. The changes are primarily textual updates to existing UI elements and documentation. The visual design, layout, and styling remain unchanged. - -## Repository Standards - -Follow established repository patterns and conventions: -- **Content Guidelines**: Use existing markdown formatting and structure (H2/H3 headers, image placement in img/ folder) -- **Documentation Patterns**: Maintain consistency with CLAUDE.md and STYLE.md formatting -- **Commit Conventions**: Follow existing commit message patterns observed in git history -- **Pre-commit Hooks**: Ensure changes pass front-matter validation and markdown linting (`npm run lint`) -- **Testing**: Verify that `npm start` and Docker commands work after changes - -## Technical Considerations - -**Node.js Package Changes:** -- Changing the package.json "name" field does not affect local development but should be validated with `npm install` -- No dependency changes are required; only metadata updates - -**Docker Naming:** -- Docker image name changes only affect local builds and documentation; no changes to Dockerfile itself -- Updated commands in CLAUDE.md should be tested to ensure accuracy - -**Docsify Configuration:** -- Changes to window.$docsify.name in index.html affect the displayed site name -- No changes to Docsify plugins or configuration structure - -**Search/Replace Strategy:** -- Use case-sensitive search for exact "DevOps Bootcamp" matches to avoid inadvertently changing technical content -- Manual review of context is required to determine if "DevOps" should be retained in each location - -## Security Considerations - -No specific security considerations identified. This is a text-based rename with no impact on authentication, authorization, data handling, or sensitive information. - -## Success Metrics - -1. **Branding consistency**: 100% of user-facing "DevOps Bootcamp" references updated to "Engineering Bootcamp" (excluding intentional "DevOps" in technical content) -2. **Technical functionality**: All npm and Docker commands work successfully with updated naming -3. **GitHub URL documentation**: GitHub issue created with complete enumeration of all repository URL references (33+ locations) -4. **Content clarity**: Introductory content clearly explains the broader Engineering Bootcamp concept and expansion into software development topics -5. **Quality assurance**: All changes pass markdown linting (`npm run lint`) and front-matter validation - -## Open Questions - -No open questions at this time.
