Documents changes from microsoft/aspire#19430

@mitchdenny

Targeting release/13.6 based on the source PR milestone 13.6.

Why

microsoft/aspire#19430 fixes Kubernetes hostname publishing and routing: WithHostname(...) on an AddIngress/AddGateway now applies to hostless WithPath/WithRoute calls instead of leaving them as catch-all rules, while WithDefaultBackend(endpoint) keeps generating a catch-all rule as before. The PR body's "User-facing usage" section shows this new scoping behavior in both C# and TypeScript AppHost samples, which triggered the pr_body_has_user_facing_section signal — the existing docs describe WithHostname/WithPath/WithDefaultBackend but didn't previously explain this inheritance rule.

What changed

  • src/frontend/src/content/docs/deployment/kubernetes-ingress.mdx: added a new "Hostname inheritance for paths and routes" section after the path-routing example, explaining that WithHostname(...) now scopes hostless paths/routes, that explicit per-path/route hostnames still take precedence, and that WithDefaultBackend(...) remains an unscoped catch-all (including its TLS compatibility rule). Includes a version note that this inheritance behavior applies from Aspire 13.6 onward.

No new pages were created; this is a targeted addition to the existing Ingress/Gateway walkthrough page since the behavior applies to both AddIngress and AddGateway (the Gateway-specific AKS walkthrough already links back to this page for the shared concepts).

🤖 Automated docs-accuracy review — PR #1574

Source of truth: microsoft/aspire@main @ 1cdf7d17248ae78ee018abbc314f772ace5e624d — contains source PR microsoft/aspire#19430 (merge 6785869656, "Fix Kubernetes hostname publishing and routing").

⚠️ Branch mismatch (non-blocking). This PR targets release/13.6, which does not exist in microsoft/aspire. Verified against main (milestone 13.6), which contains the change. The 13.6-onward version claim is corroborated below.

Phase A — claims: 7 non-narrative claims → 6 verified · 1 verified-with-nuance · 0 contradicted · 0 unverifiable.
Phase B — doc-tester: exercised /deployment/kubernetes-ingress/ → HTTP 200, 0 console errors/warnings; insertion region + reused components (Tabs, titled code, <Aside>) render; no new links/components. Knowledge gap: local build predates this PR.

Verdict: 🟡 COMMENT

The behavior — hostless-path/route hostname inheritance, explicit-hostname precedence, default-backend catch-all + TLS-compat rule, and the 13.6-onward attribution — is all verified against source. One minor nuance worth flagging (multi-hostname behavior); nothing blocking.


Phase A — Claim verification

✅ Version framing is accurate this time

Unlike the DevTunnel note (#1570), the 13.6-onward claim here checks out precisely:

  • The inheritance logic (AddPathForHost / ResolveHostnamesAsync in KubernetesEnvironmentResource.cs) is present on main only and is absent from release/13.5, which still uses pathsByHost = ingressResource.Paths.GroupBy(p => p.Host ?? string.Empty) — i.e., hostless paths → empty host → catch-all. That exactly matches the doc's "in earlier versions, hostless paths and routes were generated as catch-all rules."
  • upstream now carries GA tags v13.5.0–v13.5.3; there is still no v13.6 tag (13.6 is the current main milestone). Since 13.5.x GA lacks the change and it lives on the 13.6 milestone, "from Aspire 13.6 onward" is correct.

ℹ️ Nuance worth flagging (non-blocking) — multi-hostname fan-out & Gateway limit

WithHostname(...) can be called more than once. When it is, a single hostless path/route is emitted once per configured hostname, not merged into one rule. The source snapshot AddIngress_WithHostname_AppliesToHostlessPath sets two hostnames and produces the /api path under both api.example.com and www.example.com. Additionally, for Gateways, a hostless route inheriting more than 16 hostnames throws (HttpRouteHostnameLimit, pointing users to explicit WithRoute(hostname, path, endpoint)). The doc's singular "set the hostname once and reuse it" framing is correct for its single-hostname example, but a one-line note about the multi-hostname fan-out (and the Gateway 16-hostname cap) would make the section complete. Optional.

Claim verdicts (7) with evidence, against microsoft/aspire@1cdf7d17
# Type Claim Verdict & evidence
C1 api-shape WithHostname(...) exists on Ingress & Gateway (incl. string overload) verified — api/Aspire.Hosting.Kubernetes.cs: Ingress L150/L153, Gateway L99/L102.
C2 api-shape WithPath/WithRoute exist, incl. host-scoped WithPath(host, path, endpoint) / WithRoute(host, path, endpoint) verified — WithPath L168 & L171; WithRoute L105 & L108.
C3 api-behavior WithHostname(...) applies to hostless WithPath/WithRoute (they inherit the hostname) verified-with-nuance — hostless path → foreach (hostname in resolvedHostnames) AddPathForHost(hostname, path); Gateway → httpRoute.Spec.Hostnames.AddRange(resolvedHostnames). Snapshots AddIngress_WithHostname_AppliesToHostlessPath, AddGateway_WithHostname_AppliesToHostlessRoute. Nuance: multi-hostname fan-out (one rule per hostname) + Gateway HttpRouteHostnameLimit (16) not mentioned.
C4 api-behavior An explicit per-path/route hostname takes precedence over WithHostname(...) verified — if (path.Host is { } explicitHost) AddPathForHost(explicitHost, path); (explicit branch first). Test AddIngress_WithHostAndPath_GeneratesHostRule.
C5 api-behavior WithDefaultBackend(endpoint) stays a catch-all (no host) incl. the TLS compatibility rule verified — comment "A default backend remains catch-all even when hostnames are configured. Only synthesize host rules for TLS…"; guard DefaultBackend is not null && Tls.Count > 0. Tests AddIngress_HostnameWithDefaultBackendWithoutTls_DoesNotGenerateHostRule + AddIngress_TlsWithDefaultBackend_AutoGeneratesHostRule.
C6 api-shape WithTls() (parameterless) exists on Ingress verified — api/...cs L180 (parameterless; string/Parameter overloads L174/L177).
C7 version / api-behavior Inheritance applies "from Aspire 13.6 onward"; earlier versions were catch-all verified — logic on main only; absent from release/13.5 (retains GroupBy(p => p.Host ?? string.Empty)). No v13.6 tag yet; change on main milestone 13.6; 13.5.x GA lacks it.

Phase B — doc-tester report

Focus: new "Hostname inheritance for paths and routes" section · Route: http://localhost:51482/deployment/kubernetes-ingress/ · Tester: doc-tester skill (blind-user; no source reading).

Category Passed Failed Warnings
Content accuracy (rendered) n/a 0 0
Components / rendering 3 0 0
Links 0 new 0 0

Critical issues: none. Warnings: none.

Passed checks

  • Page health: GET /deployment/kubernetes-ingress/ → 200, title "Expose services with Ingress and Gateway API | Aspire". 0 console errors, 0 warnings.
  • Insertion region intact: new H2 sits between "Routing paths to services" and "## TLS and certificates" (#tls-and-certificates, renders). The preceding paragraph already documents the host-scoped WithPath("api.example.com", "/", endpoint) overload and WithDefaultBackend(endpoint) — the exact APIs the new section elaborates.
  • Code shape already renders: the page already shows .WithHostname("app.example.com").WithTls(); and ingress.WithPath("/api", …) / ingress.WithPath("/", …) in titled Tabs — identical to the new example ⇒ zero render risk.
  • Components reused, none new: the new <Aside type="note"> maps to the already-rendering "Note" complementary; Tabs + titled code figures already render.
  • Links: added prose has no new links.

Knowledge gap — running build predates PR #1574

  • The local frontend doesn't contain this change, so the literal new section couldn't be rendered. I validated page health, the insertion anchors, that the new section's code shape + Aside/Tabs already render on this page, and that no new links/components are introduced. Reused-pattern, no-link addition ⇒ render failure effectively impossible.

Automated review · Phase A read microsoft/aspire@main 1cdf7d17 (source of truth = upstream) · Phase B via doc-tester (blind-user, Playwright).

`WithHostname(...)` on the Ingress or Gateway sets the hostname that applies
to any path (`WithPath`) or route (`WithRoute`) you add **without** an
explicit hostname of its own. This lets you set the hostname once and reuse it
across every hostless path or route:

If a path or route specifies its own hostname — via the host-scoped
`WithPath("api.example.com", "/", endpoint)` overload, or the equivalent on
`WithRoute` — that explicit hostname takes precedence over the one from
`WithHostname(...)`.

`WithDefaultBackend(endpoint)` is unaffected by `WithHostname(...)`: the
default backend always generates a catch-all rule (no `host` restriction) so
it keeps accepting any traffic that doesn't match a more specific path or
route, including the TLS compatibility rule Aspire generates for it.

## Summary

<!-- Describe what this pull request changes and why. -->

Reconcile the 13.6 wiki audit and **all 25 open `docs-from-code`
proposals targeting `release/13.6`** against the actual release source.
Add missing canonical guidance rather than putting all coverage in
What's new. This is a new, isolated feature PR into `release/13.6`; it
does not update the release rollup #1599, merge or close another
proposal, or push directly to a release branch.

**Draft with explicit remaining packaging/validation gates:** the six
REPL walkthroughs are source-verified, but current publicly available
13.6 packages do not contain the late `WithRepl` exports. Generated API
catalogs have deliberately not been fabricated or refreshed from 14.x.
See the open checklist below.

### Evidence baseline

- Documentation base: `717442f6666948bcf77f3d704dc2dadf7c080ec2`.
- Product source of truth:
[`microsoft/aspire@e8fd6fbb954f50ccd2e66479538392f65e13e71d`](https://github.com/microsoft/aspire/tree/e8fd6fbb954f50ccd2e66479538392f65e13e71d),
current `release/13.6` at audit time. Source was read from that Git
object, not the stale source working directory.
- [13.6 wiki](https://github.com/microsoft/aspire/wiki/13.6-Change-log)
snapshot `8e01a371d4f16a1306e48174d4cf1fdeca714348`, whose cutoff is
product PR 20511. Later backports 20541/20546/20548 are included here.
- Proposal base branches alone were **not** used as proof of release
membership. Direct ancestry and known release backports were checked.
Four fallback-targeted proposals are excluded below.
- Wiki link corrections: its REPL link #1752 actually covers Sandboxes;
the REPL proposal is #1740. Its AOT link #1714 covers PFX certificates,
not AOT.

### Complete audit-gap checklist

Checked items mean documentation coverage is implemented, not that cloud
deployment or every product runtime scenario was executed.

- [x] **1. Dotnet API graduation:** correct removal to **13.6**, not
14.0, in What's new, both Dotnet guides, and the diagnostic page;
preserve the prerelease package caveat. This applies to core
`AddDotnetProject`, `DotnetProjectResource`, and related
`WithBuildEnvironment` overloads, not all uses of the diagnostic.
Source: microsoft/aspire#20496.
- [x] **2. Sandboxes:** remove obsolete API suppressions in the article
and deployment guide while preserving Azure service preview/access and
prerelease package limitations. Source: microsoft/aspire#20483.
- [x] **3. Docked REPL documentation:** all six
PostgreSQL/MySQL/MongoDB/SQL Server/Redis/Valkey guides plus the article
now cover opt-in `WithRepl`/`withRepl`, run-only availability, actual
client privileges, credential handling, and explicit exit versus closing
a viewer. Source: microsoft/aspire#20419, backport of
microsoft/aspire#20231. Package-backed checks remain open below.
- [x] **4. Terminal CLI flag:** update current 13.6 article,
`with-terminal`, and all three terminal command references. Preserve
`terminals.v1` and experimental hosting API distinctions. Current
configuration/schema data had no flag entry to remove; historical 13.5
notes remain historical. Source: microsoft/aspire#20548.
- [x] **5. First-party Rust:** rewrite both canonical Rust guides around
`Aspire.Hosting.Rust`; document Cargo versus application arguments,
typed targets, debugging, generated Dockerfiles, workspace context, ABI
constraints, and Toolkit migration. Bacon remains explicitly
Toolkit-only. Add exact first-party package mapping. Source:
microsoft/aspire#18906 and current Rust README.
- [x] **6. Agent setup:** align command reference, skills guide,
AI-agent guide, and article on MCP opt-in, `--mcp`,
chained/non-interactive behavior, seven-skill catalog, Project v2
migration, and Copilot app detection. Also fix stale default-selection
text: all applicable bundle skills are preselected; companion tools
remain opt-in. Sources: microsoft/aspire#19893, microsoft/aspire#20405,
microsoft/aspire#19820.
- [x] **7. Deno AppHost runtime:** document Deno 2+ detection, commands,
permissions, native watch/type checking, doctor, and `DENO_CERT`,
separately from Deno guest hosting. Source: microsoft/aspire#18627,
distinct from microsoft/aspire#18628.
- [x] **8. Native AOT / Fluent UI v5:** concise article, dashboard
exploration, and standalone guidance; automatic packaged-dashboard
selection, no invented performance figures. Source:
microsoft/aspire#19565 and release packaging sources.
- [x] **9. NuGet:** document bundled in-process operations, credential
providers, non-interactive authentication, and realistic
troubleshooting. Correct the proposal's `dotnet nuget locals`
authentication advice: cache commands do not authenticate a feed.
Source: microsoft/aspire#20391.
- [x] **10. Multithreaded builds:** article and coordinated-build guide
explain `-mt`, SDK detection, distinct project/file-based SDK floors,
and fallback. Source: microsoft/aspire#20441.
- [x] **11. Radius:** add a real deployment guide with C#/TypeScript
setup, recipe-backed connections versus local endpoints, per-resource
credential behavior, unauthenticated Redis limitation, secret exposure
boundaries, and actionable runtime diagnostics 070–091. Wire navigation
and exact package mapping. Source: microsoft/aspire#19555 and release
README.
- [x] **12. Connection aliases:** replace contradictory no-encoding
guidance, retain composed logical-key-first lookup and portable-target
behavior, explain collision detection and custom-publisher metadata.
Source: microsoft/aspire#19729.
- [x] **13. Connector Namespace / Toolbox / provisioning:** add
Connector Namespace walkthrough, security/consent/revocation limits and
mapping/sidebar; add Foundry Toolbox walkthrough, connection properties,
roles, index prerequisites, approval enforcement boundaries, immutable
versions, and existing-resource behavior. Extend existing Azure
provisioning guide without a duplicate page. Sources:
microsoft/aspire#19024, microsoft/aspire#17742, microsoft/aspire#20131.
- [x] **14. Remaining high-impact items:** article covers opt-in
manifest-aware DNX and new-template CLI bundling (existing SDK guides
retained), migration skill and Copilot app detection; canonical inline
`CsiVolumeSourceV1`/`VolumeV1.Csi` example, management links, Cosmos
vNext telemetry, and AI Inference `GetModelInfoAsync`/`/info` health
checks with `DisableHealthChecks`. No Azure OpenAI health-check claim.
Sources: microsoft/aspire#19310, microsoft/aspire#19076,
microsoft/aspire#19826, microsoft/aspire#20070, microsoft/aspire#15671,
microsoft/aspire#15969.
- [x] **15. All 25 proposal dispositions:** listed below, including
newer dashboard backports and four exclusions. Existing Sandbox
inference coverage is retained rather than copied from a stale draft.
- [ ] **16. Refresh generated API/catalog/Twoslash data from an official
post-backport 13.6 build.** Existing `26473.12`/`a11eca96` data remains
untouched. The newest public `dotnet9` feed package checked,
`13.6.0-preview.1.26474.10` at
`43496a2a306c81c862c947b11b4f4e5494b6fe08`, still has no Redis
`WithRepl` in its actual package XML. Do not use 14.x, hand-edit
declarations, or attribute source changes to older binaries.
- [ ] **Validate the six REPL examples against that actual post-backport
SDK and running clients.** Their new TypeScript fences are plain
TypeScript, not annotated with unsupported Twoslash data. No existing
diagnostics are allowlisted or suppressed; no generated API exports are
fabricated. Enable Twoslash when the genuine catalog catches up.

### Important source-verified corrections to proposals / earlier audit
assumptions

-
[`BlazorGatewayExtensions.cs`](https://github.com/microsoft/aspire/blob/e8fd6fbb954f50ccd2e66479538392f65e13e71d/src/Aspire.Hosting.Blazor/BlazorGatewayExtensions.cs):
`AddDotnetProjectBlazorGateway` and the Dotnet `WithBlazorClientApp`
overload still carry `ASPIREDOTNETPROJECT001`; the class carries
`ASPIREBLAZOR001`. They share `WithBlazorClientAppCore`/`WithBlazorApp`
and the publish-companion path. Thus neither blanket diagnostic
retirement nor the proposal's old run-only claim is correct.
-
[`SkillDefinition.cs`](https://github.com/microsoft/aspire/blob/e8fd6fbb954f50ccd2e66479538392f65e13e71d/src/Aspire.Cli/Agents/SkillDefinition.cs)

selects the applicable catalog defaults for both flows. MCP has its own
standalone-only binding.

supplies the resource-specific credential rules and publish diagnostics,
not assumptions about local endpoints.

stand-ins; no claim of running those apps or provisioning cloud
resources.
- **10 TypeScript samples pass `tsc`** under `strict`, `NodeNext`, and
`ES2022` against three **unmodified actual SDK files**, not just the
site's declaration bundle. The fixture uses the exact `e8fd6fbb` release
`AtsCapabilityScanner` and genuine `26473.12`
TypeSystem/code-generator/integration binaries, whose informational
source is `a11eca96`. This is an isolated local generation fixture,
**not** a claim that official CLI generation or a new packaged release
was tested. An attempted restore with the older handed-off local CLI
could not discover an AppHost server; the bounded direct generator
fixture was used instead.
- The SDK scan is **not globally warning-free**: it reports a Radius
`withContainerImage` collision on `CSharpAppResource` and an App
Configuration `createRoleAssignment` overload collision. None of the
compiled examples calls those colliding methods; the warnings are
retained in evidence, not suppressed, and no generated declarations were
edited.
- Browser: Connector Namespace, Radius, both Rust pages, Foundry
hosting, and What's new return **HTTP 200**, correct headings, and no
rendered Twoslash errors. New guide/article page-local anchors and the
cross-page Blazor anchor resolve. Connector/Radius mobile layouts have
no horizontal overflow; Connector language-tab interaction works.
Standalone Astro preview emits expected `/api/live` 404s because
StaticHost is not running.
- `git diff --check` passes. No production `pnpm build`, cloud
deployment, REPL runtime session, full product suite, or blanket
validation of every pre-existing example was performed.
- Generated C#/TypeScript API data, declaration bundles, integration
catalogs, image catalogs, and contributor data are unchanged. Only the
authored package-to-guide mapping is updated.

**Before merging:** complete the two packaging/REPL checkboxes above,
inspect CI, and obtain human review. This PR intentionally does not
close or merge the source documentation proposals.
