feat(ci): deploy the AWS control plane from GitHub Actions, with rollback - #1801
Conversation
A deploy has to move the image and put it back, so Terraform cannot own the deployed version: CONTROL_PLANE_IMAGE becomes its own parameter, created once and then left alone, the same inventory-not-values boundary the secrets use. After the first deploy, control_plane_image_tag no longer describes what is running -- deployed_image_parameter says where that lives. The deploy role authenticates over OIDC, so no AWS key is stored in the repository. Its trust policy pins the repository and the GitHub environment the job requested, which makes an environment's reviewers an AWS access gate rather than a UI convention. It can push to one ECR repository, move one SSM parameter, and run one document on one instance; it cannot read the secrets beside that parameter. The OIDC provider is an account-wide singleton, so the second environment in an account has to be handed the first's ARN. Adds the module's first plan-time tests. terraform validate does not evaluate locals, so nothing in CI planned this module at all.
open-inspect.service is Type=oneshot, so a systemctl restart runs ExecStop before ExecStartPre reaches S3, SSM and ECR -- the running stack is gone before the fallible part of the deploy begins, and a transient failure leaves nothing serving and nothing to roll back to (COL-138). open-inspect-deploy fetches, pulls and swaps instead, so anything that fails before the swap changes nothing. That is also what lets a rollback be the same command with the parameter put back. deploy-aws.sh owns the sequence because the value to restore has to be read before anything moves. Health is six consecutive checks: one 200 proves the port is open, not that the deployment works. A rollback that succeeds still fails the job. The tests run that path against a stubbed AWS CLI and a health check that can be made to fail or to flap, because otherwise nothing exercises it until the day it is needed.
Native arm64 runner rather than QEMU: the instance is Graviton and the image has no amd64 build. The environment is picked by a job that declares none, so a repository that has never configured one does not need it to exist for this workflow to pass. Deploying on push is opt-in through a repository variable; production is left to a manual dispatch behind the environment's reviewers. No Terraform runs here. An infrastructure change is still terraform apply, and the runbook now says so where it used to promise CI would take it over.

Summary
PR #1801, feat(ci): deploy the AWS control plane from GitHub Actions, with rollback, by @ColeMurray changes 21 files (+1,119/-21). It adds an OIDC-scoped AWS deployment workflow, SSM-based image activation, rollback health checks, Terraform IAM resources, tests, and runbook updates. The overall security shape and test harness are thoughtful, but the current upgrade and timeout behavior can prevent existing stacks from deploying or can undermine rollback.
Critical Issues
- [Correctness]
terraform/modules/aws-control-plane/config.tf:126- The existing SSM parameter changes Terraform addresses without amovedblock, risking a conflicting or destructive replacement instead of preserving the deployed value. - [Correctness]
terraform/modules/aws-control-plane/templates/user-data.sh.tftpl:221- Existing instances ignore user-data changes, so the remote helper required by every deployment is never installed by the documented enablement apply. - [Rollback]
.github/workflows/deploy-aws.yml:147- The workflow stores a mutable commit tag rather than the immutable digest the design and IAM comments describe, so a same-SHA rebuild cannot roll back. - [Concurrency]
scripts/deploy-aws.sh:63- The SSM delivery timeout does not stop an already-running shell command; the script can start rollback concurrently with the original activation. - [Reliability]
.github/workflows/deploy-aws.yml:100- The script's maximum deploy plus rollback budget consumes the entire job timeout before build and push time, allowing Actions to cancel rollback.
Suggestions
No additional non-blocking suggestions beyond adding regression coverage for the state-upgrade, same-SHA rebuild, and command-timeout paths while addressing the blockers.
Nitpicks
None.
Positive Feedback
- The OIDC trust policy pins both repository and environment, and the deploy permissions are narrowly scoped to the ECR repository, one SSM parameter, and one instance.
- The deploy test harness exercises rollback, sustained health, flapping health, and failed remote commands rather than only the happy path.
- The runbook clearly separates application deployment from infrastructure apply responsibilities.
Questions
None.
Verification
The focused deploy suite passes all 6 tests, the shell script parses cleanly, and all reported GitHub checks are green. Terraform was not available in the local review environment; the PR's remote Validate check passed.
Verdict
Request Changes - the blocking upgrade and rollback safety issues should be resolved before merge.
| # The consequence worth knowing: after the first deploy, `control_plane_image` | ||

Blocking - preserve existing Terraform state. Before this PR, this same physical parameter is managed as aws_ssm_parameter.config["CONTROL_PLANE_IMAGE"]. Changing it to a new resource address without a moved block makes an upgrade plan an unrelated destroy/create against the same SSM name; depending on ordering, that can conflict, delete the parameter temporarily, or reset the externally managed value to local.image. Can we add moved { from = aws_ssm_parameter.config["CONTROL_PLANE_IMAGE"] to = aws_ssm_parameter.deployed_image }? It is a no-op for fresh state and lets ignore_changes preserve the existing value.
There was a problem hiding this comment.
Done in 60558132e. The moved block is in the module, so it travels with it rather than needing to be written into each root:
moved {
from = aws_ssm_parameter.config["CONTROL_PLANE_IMAGE"]
to = aws_ssm_parameter.deployed_image
}| # nothing at all, which is what makes a failed deploy a no-op rather than an | ||
| # outage -- and what lets a rollback be the same command with the parameter put | ||
| # back. | ||
| cat >/usr/local/bin/open-inspect-deploy <<'SCRIPT' |
There was a problem hiding this comment.
Blocking - existing instances never receive this helper. aws_instance.this ignores user_data_base64, and cloud-init runs this template only on first boot. Enabling github_deploy with a normal terraform apply therefore creates the role but leaves /usr/local/bin/open-inspect-deploy absent on an existing I-2 host, so every send-command fails. Can we either distribute this helper through an artifact that current hosts fetch, or make CI enablement explicitly replace/install it before the workflow can run and cover that upgrade path?
There was a problem hiding this comment.
Right, and the general form is worse than this one helper: user_data_base64 is ignored, so anything a deploy assumes cloud-init installed is an assumption about how old the instance is.
Fixed in b4275678c by your first option. The activation is now a stack file, and open-inspect-fetch-config already syncs those from S3 before every start — so it reaches any instance on the next activation, and the sequence can change again later without replacing one. The remote command names the fetch and that script, both of which resolve on any host. A test asserts send-command never names open-inspect-deploy.

Blocking - this reference is not immutable. The module configures this ECR repository with image_tag_mutability = "MUTABLE", while the value emitted below is $REPOSITORY:$GITHUB_SHA. Re-running a SHA can overwrite the currently deployed tag before deploy-aws.sh snapshots previous; if that rebuild is unhealthy, previous and IMAGE_REF name the same bad manifest and rollback cannot restore the old image. Please resolve the pushed manifest and store $REPOSITORY@sha256:... in SSM, which also matches the digest-resolution comment in the IAM policy.
There was a problem hiding this comment.
Confirmed, and the IAM comment already claimed the deploy resolved a digest — it didn't. Fixed in 9dd8d71cb: the push resolves via aws ecr describe-images and stores REPOSITORY@sha256:…, with a guard that fails the step if the answer isn't a digest. :latest still moves, for a first boot before any deploy has run.

There was a problem hiding this comment.
Blocking - the original activation can keep running during rollback. SSM's send-command --timeout-seconds only bounds how long a command may wait to start; it does not bound an AWS-RunShellScript invocation after execution begins. When the local 600-second deadline expires, this script immediately writes the previous image and sends a second activation while the first command may still be pulling or updating the same Compose project, so the first command can race with or outlive rollback. Please pass the document's executionTimeout and cancel/wait for any locally timed-out command before rollback (with the corresponding ssm:CancelCommand permission), or otherwise serialize the remote operation.
There was a problem hiding this comment.
Confirmed. Fixed in b4275678c with executionTimeout in --parameters rather than cancel-and-wait: the document enforces its own bound, so the command is already terminal, and it needs no extra IAM. The local deadline now sits COMMAND_GRACE_SECONDS past it, to read the status SSM writes when it stops the command.
compose up also got --wait-timeout, since a bare --wait was the way to hang past any budget.

There was a problem hiding this comment.
Blocking - the job timeout cannot contain the rollback budget. The configured maxima are 10 minutes for activation plus 5 minutes for health, then another 10 plus 5 for rollback: the full 30-minute job timeout, before checkout, image build/push, polling overhead, or curl overruns. In the slow failure case Actions will forcibly cancel the job before rollback verification completes. Please leave explicit margin by raising the job timeout above the end-to-end worst case or shortening the script budgets.
There was a problem hiding this comment.
Confirmed: 600+300+600+300 was exactly the 30 minutes, before checkout and the build. Raised to 50 in 9dd8d71cb — the script's budgets are what they are because the instance pulls the image over its own link, so the margin belongs on the job.

- Around line 140-149: Update the deployment workflow to resolve the digest of
the pushed immutable image after pushing REPOSITORY:$GITHUB_SHA, then store and
use the REPOSITORY@sha256:... reference for deployment and rollback instead of
the mutable tag. Keep the latest tag push for first-boot behavior, but ensure
the persisted SSM image reference is digest-pinned.

existing dedicated CONTROL_PLANE_IMAGE resource.
- Around line 126-129: In the Terraform module, add a moved block mapping
aws_ssm_parameter.config["CONTROL_PLANE_IMAGE"] to
aws_ssm_parameter.deployed_image so Terraform preserves the existing SSM
parameter state during the resource rename and avoids replacing its CI-owned

…ary honest Review findings on the AWS deploy module. - The deployed-image parameter changes Terraform address in this branch, from one entry of aws_ssm_parameter.config to its own resource. Without a moved block that is a destroy and a create against one SSM name, and whichever order Terraform picks either conflicts or resets the value CI last deployed. - Nothing stopped a caller setting CONTROL_PLANE_IMAGE through var.config, which would be a second resource writing that same name. It is now rejected with a message naming what to use instead. - GitHub percent-encodes a colon inside a claim's context value, so an environment named "aws:staging" arrives as "aws%3Astaging" and the trust policy pinned a subject no token carries. The subject is now a named local, which is also what makes it assertable: the policy document is mocked away under terraform test, and the subject is the part of it worth holding still. - ssm:ListCommandInvocations was granted and never called. It takes no resource-level scope, so it read the output of commands this role did not send. Three new runs cover the escaped subject, the immutable subject format a repository created after 2026-07-15 gets, and the reserved config key.
aws_instance.this ignores user_data_base64, and cloud-init runs once, so whatever a host was given at its first boot is what it has for its lifetime. The activation helper this branch added went into user data, which meant enabling CI deploys on an existing instance created the role and then sent it a command naming a file that was never installed. The activation now ships as a stack file. open-inspect-fetch-config already syncs those from S3 before every start, so it arrives on the next activation of any instance, and the sequence can change again later without replacing one. The remote command names that fetch and that script -- both of which resolve on any host -- rather than the helper, which stays as the convenience it always was. Two bounds go with it: - executionTimeout on the document. --timeout-seconds bounds delivery only: once AWS-RunShellScript starts, it runs to completion whatever this script does, so a hung activation could still be pulling and recreating containers while the rollback wrote the old image and sent a second one. The local deadline now sits past the document's, to see the status SSM writes when it stops the command. - --wait-timeout on compose up. Bare --wait waits indefinitely for a health check a broken image never passes, and the deploy cannot start its rollback until the command returns.
The ECR repository is MUTABLE and the workflow stored REPOSITORY:$GITHUB_SHA. Re-running the workflow on a commit that is already deployed repoints that tag at the new build, so the string a rollback restores names the image it is rolling back from. The push now resolves what it pushed to a digest and deploys that; the IAM policy already allowed the lookup, and its comment already claimed the deploy did it. Also from review: - id-token: write was granted workflow-wide, so the job that only picks an environment name could mint an OIDC token too. Permissions are now per job. - The environment name is a repository variable somebody typed, and it went on to name a job, a concurrency group and -- interpolated as a GitHub expression into a run block -- a shell command. It is validated before any of that, and the one remaining use reads it from env. - The job timeout was exactly the sum of the script's own worst case, leaving nothing for the build and push in front of it. Actions would have cancelled the job mid-rollback.

Terraform Validation Results
Pushed by: @ColeMurray, Action: |
terraform.yml's path filter is the union of every service's, so a change to the web app was running the whole AWS suite -- about 40s of a 57s job, on a PR that could not affect any of it. The three AWS steps move to their own workflow with a filter that names what actually feeds them: the module, the two environments, the compose files and the Caddy/Litestream configs the module uploads verbatim, and the two shell scripts. `terraform fmt` and the production environment's own tests stay put, since `terraform/**` already covers those. Their step ids went with them. Nothing referenced aws_stack, validate_aws or test_aws -- the Validation Results comment only reports fmt, init, validate and test -- so the AWS steps were never in that table, and are not missing from it now. deploy-aws.yml gets the same treatment from the other side. It ran a job on every push to main touching the control plane, to print a notice saying no environment was configured. `vars` is readable in a job-level `if`, so an installation that has set none now skips every job instead. The empty-name branches inside the step go with it: the job cannot start without a target any more. Measured on the previous run: static checks 1.4s, environments validate 23s, module test 12s.

…in relies on Second review round. The polling loop checked SECONDS but the calls inside it were unbounded: the CLI waits 60s to connect and 60s to read, three attempts over, so one poll started near the deadline could run minutes past it. Both reads now carry connect and read timeouts. This does not change whether a rollback can overlap the command it is rolling back -- `executionTimeout` had already ended that -- only how promptly the loop notices. The trust policy pins the repository and the environment, and names no branch. GitHub creates a referenced environment with no protection rules if it does not exist, so without a deployment-branch rule on the environment a workflow dispatched from any branch presents the same subject and assumes the same role. That rule is not something Terraform here can set, so the runbook now makes it a step with the reason attached, rather than "add reviewers if it is production", and the workflow header says the same. The send-command assertions parsed a substring, which would have passed with the second command missing or the parameters malformed. They now parse the recorded document and compare the command list and executionTimeout outright. Both breakages are caught; the first is the one the substring check let through.

Third review round. The SSM payload sent the fetch and the activation as two commands. AWS-RunShellScript reports the exit status of the last command it ran, so a fetch that failed ahead of an activation that succeeded was reported as a success -- and that activation brought up the `.env` already on the instance, naming the previous image. `compose pull` and `up` are no-ops, the health check passes because the previous image is the one that was working, and the deploy reports an image the instance never fetched. Nothing rolls back, because nothing looks wrong. They now go as one `&&` command, which is what the instance's own `open-inspect-deploy` does under `set -e`; inlining the steps had dropped it. The new test runs the payload's command with its two absolute paths stubbed, so it proves the shell between them rather than asserting a string. Reverting the `&&` fails it, and fails the payload assertion too. `check-aws-stack.sh` had a comment starting with the word "shellcheck", which shellcheck reads as a directive: SC1072/SC1073, an error that stops the rest of the file being checked. CI never saw it because the script lints the rendered template and the two deploy scripts but not itself. It now lints itself as well. Both checkouts drop the git token they do not use. `aws-stack.yml` runs pull-request code, and the deploy job already holds AWS credentials; six other workflows here already set this.

Closes COL-112 (I-3).
The Cloudflare deploy is
terraform applyfromterraform.yml. This is the AWS equivalent, and deliberately a different shape: no Terraform runs here. The image is built and pushed, the deployed-version parameter is moved, and the instance activates it over SSM. Infrastructure changes stay aterraform apply, and the runbook now says so where it used to promise CI would take that over too.Three things the merged I-2 module changed about the plan
The issue was written before I-2 shipped, so its deploy step described editing
/opt/open-inspect/.envon the instance. That file is rewritten wholesale from SSM on every activation, so a hand-edit is erased by the next one. I updated the issue and built what the module actually supports.Terraform had to stop owning the deployed version.
CONTROL_PLANE_IMAGEwas a derived value in thefor_eachconfig map, so the nextterraform applywould revert whatever CI deployed — and a rollback needs to move it without an apply at all, since CI knows the digest it just pushed and Terraform does not. It is now its own resource, created once and then left alone: the same inventory-owned-values-not boundary the secrets already use. The consequence is worth knowing and is documented — after the first deploy,control_plane_image_tagno longer describes what is running.The OIDC role did not exist. The issue said "a role created in I-2"; I-2 shipped the instance role and the DLM role only. Creating it was in scope here.
COL-138 belonged in this PR rather than after it.
open-inspect.serviceisType=oneshot, sosystemctl restartrunsExecStopbeforeExecStartPrereaches S3, SSM and ECR — the running stack is gone before the fallible part of a deploy begins. That is not a defect you can build a rollback story on top of.open-inspect-deployfetches, pulls, and swaps, so anything failing before the swap changes nothing, and a rollback is the same command with the parameter put back.Security shape
Authentication is OIDC; there is no AWS key in this repository. The role's trust policy pins the repository and the GitHub environment the job requested, so an environment's reviewers gate AWS access rather than only the UI. The role can push to one ECR repository, read and write one SSM parameter, and run
AWS-RunShellScripton one instance. It cannot read the secrets sitting next to that parameter under the same prefix.The OIDC provider is an account-wide singleton, so the second environment in an account must be given the first's ARN. That is a real trap — a second apply would otherwise fail on
EntityAlreadyExists— so it is a documented input and one of the module tests.What is verified, and what is not
Verified.
npm run test:deploy-aws— 7 tests overscripts/deploy-aws.shagainst a stubbed AWS CLI and a health check that can be made to fail or to flap. It covers the rollback, which otherwise only ever runs when something has already gone wrong. Mutation-tested: 7 of 7 deliberate breakages caught, including "rollback writes nothing", "rollback is written but never activated", "a rolled-back deploy reports success", and "health accepts a single 200".terraform teston the module — 6 runs against mocked providers: the feature off, on-and-creating the provider, on-and-reusing one, an environment name that needs percent-encoding, an immutable-subject repository, and the reservedCONTROL_PLANE_IMAGEconfig key.terraform validatedoes not evaluate locals, so until this, nothing in CI planned this module at all.scripts/check-aws-stack.shnow shellchecks both deploy scripts alongside the rendered user-data.Not verified. No part of this has run against real AWS. The environment from I-2 is torn down, and the boot path it changed — volume discovery, the Compose install, systemd ordering, the
.envwriter — has still never run on hardware in its current form. The first green deploy from this workflow is what would prove both, which is an argument for standing staging up once before this is relied on.One thing I got wrong along the way, in case it matters to a reviewer reading the comments: I restructured the module's locals believing Terraform eagerly evaluates both branches of a conditional and would fail on a null
github_deploy. The mutation test says otherwise — reverting the guard does not fail. The restructure is still the clearer code, but the comment now describes what it does rather than claiming a bug that does not occur.Review round
Ten findings fixed across
60558132e,b4275678cand9dd8d71cb; two pushed back. The three worth reading:The deploy stored a mutable tag. The ECR repository is
MUTABLE, so re-running the workflow on a commit that is already deployed repoints:<sha>at the new build — and the rollback, which restores whatever string the parameter held, would put back the image it was rolling back from. It now resolves the push to a digest. The IAM policy already permitted the lookup and its comment already claimed the deploy did it; it didn't.The activation helper could never reach an existing instance.
aws_instance.thisignoresuser_data_base64and cloud-init runs once, so a host keeps whatever it was given at first boot. Enabling deploys on a running instance would have created the role and then sent it a command naming a file that was never installed. The activation is now a stack file —open-inspect-fetch-configalready syncs those from S3 before every start — so it arrives on the next activation of any instance, and the sequence can change again later without replacing one. A test assertssend-commandnever names something cloud-init installed.--timeout-secondsdoes not bound execution. It bounds delivery; onceAWS-RunShellScriptstarts it runs to completion regardless, so a hung activation could still be pulling and recreating containers while the rollback wrote the old image and sent a second one.executionTimeoutnow bounds the document itself, and the local deadline sits past it.compose upalso gained--wait-timeout, since a bare--waitwas the way to hang past any budget.Pushed back on blue-green with a traffic switch (a different deployment architecture, and one that wants hardware before it is worth reviewing —
--wait-timeouttakes the part that sets the outage's length) and on pinning actions to commit SHAs (all eight workflows here use tags; that is a repo-wide policy change with a Dependabot config attached).CI cost
Worth stating, since most installations will never deploy to AWS. These checks need no credentials and no AWS account, so they run for everyone — but
terraform.yml's path filter is the union of every service's, which meant a web-only PR was paying ~40s of AWS Terraform work. They now live inaws-stack.ymlbehind a filter that names what actually feeds them. Anddeploy-aws.ymlused to run a job on every push tomaintouching the control plane, to print a notice that no environment was configured;varsis readable in a job-levelif, so an installation that has configured none now skips every job.Not in scope
terraform applyfrom CI. Deploys are automated; infrastructure is not, and a change to the compose files or toconfigstill needs a laptop apply before a deploy picks it up. That gap is now stated in the runbook's "Not here yet".Summary by CodeRabbit
