Summary

Force ArgoCD to replace the readiness-gate Job on upgrade, without deleting/recreating it on every no-op sync.

Motivation / Context

The readiness-gate Job's spec.selector/spec.template.metadata.labels are server-generated and immutable, so a plain Replace=true sync-option (kubectl replace) is rejected by the API server on any spec change (e.g. an image tag bump), leaving the Application permanently OutOfSync while still showing Healthy.

Fixes: #2367
Related: N/A

Type of Change

  • Bug fix (non-breaking change that fixes an issue)
  • New feature (non-breaking change that adds functionality)
  • Breaking change (fix or feature that would cause existing functionality to change)
  • Documentation update
  • Refactoring (no functional changes)
  • Build/CI/tooling

Component(s) Affected

  • Bundlers (pkg/bundler, pkg/component/*)
  • CLI (cmd/aicr, pkg/cli)
  • API server (cmd/aicrd, pkg/server)
  • Recipe engine / data (pkg/recipe)
  • Collectors / snapshotter (pkg/collector, pkg/snapshotter)
  • Validator (pkg/validator)
  • Core libraries (pkg/errors, pkg/k8s)
  • Docs/examples (docs/, examples/)
  • Other: ____________

Implementation Notes

Two-part fix, added in two commits:

  1. Job-level: argocd.argoproj.io/sync-options: Replace=true,Force=true on the readiness-gate Job's own annotations. Force=true is ArgoCD's documented delete-and-recreate fallback when a replace fails on immutable fields. Deliberately not a Helm-style sync hook — those are excluded from ArgoCD's normal drift detection, which would let an image-tag-only bump go undetected.
  2. Application-level (added after CodeRabbit review on the first commit): Force=true alone causes ArgoCD to delete-and-recreate the Job on every sync, not just genuine spec diffs, needlessly rerunning readiness checks. Empirically confirmed (real ArgoCD v3.5.1 on kind) that ApplyOutOfSyncOnly only works as an Application-level spec.syncPolicy.syncOptions setting — as a per-resource annotation token it's silently accepted but has zero effect. Added ApplicationData.ApplyOutOfSyncOnly, scoped to just the -readiness folder's Application (not applied globally) via a shared isReadinessFolder helper, rendered conditionally in application.yaml.tmpl.

Any operator who has already deployed a pre-fix bundle should expect one additional syncOptions line on their next aicr bundle regeneration — not spec drift.

Testing

go test -race ./pkg/bundler/...
golangci-lint run -c .golangci.yaml ./pkg/bundler/...
  • pkg/bundler/deployer/argocd: 87.1% coverage (+3.1% vs. main)
  • pkg/bundler/deployer/argocdhelm: 89.3% coverage (+5.4% vs. main)
  • pkg/bundler/gatemanifest: 92.7% coverage (+7.7% vs. main)
  • Golden fixtures regenerated for both deployers; diffs confirmed to touch only the new syncOptions/annotation lines
  • make qualify blocked at make test on 3 pre-existing, unrelated failures — pkg/bundler/attestation and pkg/trust (sandbox network egress blocked to tuf-repo-cdn.sigstore.dev), pkg/oci (local Helm CLI version drift). Verified identical on origin/main via git stash; none import or are imported by the changed packages.

Verified against real ArgoCD (v3.5.1) on kind, twice — once with hand-patched YAML to validate the approach, once against the actual aicr bundle output from this code:

  • No-op resync: Job UID/creationTimestamp unchanged across repeated syncs (previously changed on every sync)
  • Genuine diff (image tag bump): Job correctly deleted and replaced, new UID, new image live, Application Synced
  • No warnings/errors logged about the new ApplyOutOfSyncOnly syncOptions token

Risk Assessment

  • Low — Isolated change, well-tested, easy to revert

Rollout notes: N/A — only changes annotations AICR itself renders on the readiness-gate Job/Application; no user-facing flag, config, or API surface changes. Existing ArgoCD-deployed bundles pick up the fix on their next aicr bundle regeneration.

Checklist

  • Tests pass locally (make test with -race, scoped to touched + adjacent packages; 3 unrelated pre-existing/environment failures documented above)
  • Linter passes (make lint)
  • I did not skip/disable tests to make CI green
  • I added/updated tests for new functionality
  • I updated docs if user-facing behavior changed
  • Changes follow existing patterns in the codebase
  • Commits are cryptographically signed (git commit -S) — GPG signing info

📝 Walkthrough

Walkthrough

Argo CD readiness-gate Jobs now use Replace=true,Force=true. Readiness Applications use ApplyOutOfSyncOnly=true. The manifest generator, deployers, fixtures, and tests reflect these changes.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: ⚪ Minimal · up to aa8db

This change adjusts readiness-gate synchronization so Jobs are replaced only when their rendered specification changes; no actionable merge-blocking risk remains.

Explanation

The changes satisfy issue #2367 by adding Replace=true,Force=true for readiness-gate Jobs, enabling deletion and recreation when immutable Job fields change. The Application-level ApplyOutOfSyncOnly setting prevents unnecessary reruns while preserving drift detection.

Explanation

The code, tests, and golden fixture updates remain within the linked issue scope. The ApplyOutOfSyncOnly changes directly support the required upgrade behavior by preventing forced recreation on unchanged syncs.

Force=true alone deletes and recreates the readiness-gate Job on every
ArgoCD sync, not just genuine spec diffs, needlessly rerunning readiness
checks (CodeRabbit finding on PR #2408).

ApplyOutOfSyncOnly only works as an Application-level
spec.syncPolicy.syncOptions setting, not a per-resource annotation
(silently ignored there). Add ApplicationData.ApplyOutOfSyncOnly, scoped
to -readiness folders via a shared isReadinessFolder helper, rendered
conditionally in application.yaml.tmpl.

Verified on kind + real ArgoCD v3.5.1: no-op syncs now leave the Job's
UID unchanged; a genuine diff still correctly replaces it.

The readiness-gate Job's argocd.argoproj.io/sync-options annotation used
Replace=true alone, which maps to kubectl replace. That fails against a
live Job on any upgrade that changes the Job spec (e.g. an image tag
bump), because spec.selector and spec.template.metadata.labels are
server-generated and immutable, and the rendered manifest correctly
omits them. The Application is left permanently OutOfSync while still
showing Healthy.

Add Force=true so ArgoCD deletes and recreates the Job when a replace
fails, instead of a Helm-style sync hook: hook-annotated resources are
excluded from ArgoCD's normal drift detection, so an image-tag-only
bump could silently go undetected.

Verified against a real ArgoCD control plane in a Kind cluster: the
unpatched Replace=true annotation reproduces the exact sync failure
from the issue on an image-tag bump, and Replace=true,Force=true
resolves it (Job deleted and recreated with the new image, Application
reports Synced).

Fixes #2367
