feat: expose System API keys and observed Zitadel instance ID - #29
Conversation
Opt-in inputs keep AuthStack environment-neutral; only public keys mount into Zitadel. Read-only discovery publishes metadata for provider-managed domains. [[tasks/harmony-1847]]

It also supports optional instance discovery, which records the discovered instance ID in status and makes readiness depend on that ID when discovery is enabled.

Merge Risk: ⚪ Minimal · up to The discovery deadline no longer cuts off slow first installs, and the supported instance-recreation procedure replaces the metadata ConfigMap. No actionable merge-blocking risk remains after normal checks. Security Architecture ReviewSecurity architecture risk: 🟡 Moderate · up to Discovery is optional and has controls that limit where it sends the administrator credential. However, after an identity-service instance is recreated, a previously published instance ID can remain visible as current until the discovery resources are recreated. The documentation calls for that manual step, making the operational dependency important to review. Retained concerns

In `@apis/authstacks/definition.yaml`:
- Line 79: Update the origin validation pattern in the auth stack definition to
accept only HTTPS URLs, so the IAM admin PAT is never sent over an unencrypted
connection.
- Around line 76-79: Restrict `internalURL` to the expected in-cluster Zitadel
service, rather than accepting any HTTP(S) destination; validate the service
host before discovery can send the IAM admin PAT.
In `@functions/render/210-instance-discovery.yaml.gotmpl`:
- Around line 57-58: Update the comment above the Job name template to state
that endpoint, image, domain, or admin username changes produce a new Job; do
not claim that PAT changes trigger one.
- Around line 61-62: Update the discovery Job’s activeDeadlineSeconds to exceed
the in-script retry budget and allow time for the admin-pat Secret to become
available during first install; keep the existing backoffLimit unchanged.

Published Crossplane PackageThe following Crossplane package was published as part of this PR: Package: ghcr.io/hops-ops/auth-stack:pr-29-fa865a32a02f6f88167968a658fd560a9e06c88d |
Bind discovery to the rendered Zitadel Service, verify HTTPS certificates, disable redirects and proxy inheritance, and support explicit CA bundles. Remove the startup wall-clock deadline while retaining API retry and Job backoff limits. Correct PAT rotation documentation. BREAKING CHANGE: the opt-in discovery feature requires HTTPS by default; trusted plaintext local clusters must explicitly set allowInsecureHTTP. Harmony PR #135 includes this local-only setting. [[tasks/harmony-1847]]

AuthStack cannot currently mount System API public keys or expose the observed Zitadel instance ID needed to manage custom domains declaratively.
Adds opt-in
systemAPIUserspublic-key Secret references, opt-ininstanceDiscovery, and typedstatus.instanceId. Discovery reads the admin API and writes a narrowly scoped ConfigMap; private keys never enter Helm values or XR status. Existing cloud and local consumers retain their defaults.Validation: 16 render tests passed, four examples passed server-side schema dry-run, and the built package reconciled successfully on kind-hops. Custom-domain login was exercised through Harmony. No cloud deployment was performed. README documents discovery lifecycle when recreating a Zitadel instance.

Summary by CodeRabbit
SYSTEM_OWNERmembership when none are specified.Review fixes: discovery destinations must exactly match the rendered Zitadel Service name, namespace and port. Redirects and environment proxies are disabled; HTTPS verifies both the certificate chain and Service hostname, with an optional CA Secret. The Job no longer expires while waiting for its chart-generated PAT; execution retries and backoff remain bounded. Documentation now accurately describes Job revision triggers.
Breaking change to this PR's new opt-in API: discovery requires HTTPS by default. Trusted plaintext local clusters must explicitly set
instanceDiscovery.allowInsecureHTTP: true; this remains cleartext inside that cluster, even if ingress uses HTTPS. Harmony #135 carries the explicit local exception. AuthStack does not install or default any localhost identity. Configuring this feature (including image and chart overrides) requires administrator trust.Review validation: 17 render tests, four security tests (including eight rejected-origin cases), and XRD/generated-CRD server-side dry runs passed. The security tests exercise the actual rendered transport setup for TLS verification, redirect rejection and ignoring proxy environment variables. Run
make test-securityfor the additional rejection tests. These review changes have not been deployed to the local or cloud AuthStack.
