Summary

  • adopt existing GitHub repositories with an explicit external name
  • support token-backed Argo CD repository credentials through External Secrets
  • derive aggregate XR readiness from enabled components
  • retain already-rendered dependent resources during transient readiness changes
  • preserve explicit false values for default-true settings

Validation

  • git diff --check
  • local Hops source builds and installs succeeded; latest build is dev-1a3522fa5519
  • live GitopsStack/default/gitops reached Synced=True, Ready=True
  • adopted gitkb/harmony-gitops without creating a duplicate repository
  • Argo CD 9.7.1 and token-backed repository credentials are healthy
  • verified applications.apps.enabled: false removes the root Application and repository.autoInit: false is preserved

No new unit tests were added; validation used the existing build path and live bootstrap control plane.

Summary by CodeRabbit

  • New Features

    • Added optional ArgoCD exposure through an existing Gateway.
    • Added native Zitadel-backed OIDC authentication with RBAC and client ID status reporting.
    • Added support for importing existing GitHub repositories.
    • Added GitHub token-based repository credentials alongside GitHub App credentials.
    • Added a complete Zitadel OIDC configuration example.
  • Documentation

    • Expanded setup guidance, prerequisites, configuration reference, and repository status details.
    • Updated ArgoCD Helm chart version documentation.
  • Bug Fixes

    • Improved reconciliation when applications or repository credentials already exist.

Review Change Stack

📝 Walkthrough

Walkthrough

The GitopsStack now supports Gateway exposure, Zitadel-backed ArgoCD OIDC, imported GitHub repositories, GitHub token credentials, conditional readiness, status client IDs, and expanded examples and validation.

Changes

GitopsStack Integrations

Layer / File(s) Summary
Configuration contracts and state initialization
README.md, apis/gitopsstacks/definition.yaml, functions/render/000-state-init.yaml.gotmpl, functions/render/210-github-repository.yaml.gotmpl
The API, documentation, and state initialize Gateway exposure, Zitadel OIDC, repository import, and GitHub token settings with validation and defaults.
Repository credentials and application readiness
functions/render/220-argocd-projects-app.yaml.gotmpl, functions/render/230-argocd-crossplane-apps.yaml.gotmpl, functions/render/240-external-secret-argocd-repo.yaml.gotmpl, functions/render/010-state-status.yaml.gotmpl
Repository credentials support GitHub tokens or GitHub Apps. Existing applications and credentials can satisfy readiness gates.
ArgoCD exposure and Zitadel resource composition
functions/render/200-helm-release-argocd.yaml.gotmpl, functions/render/400-zitadel-credentials.yaml.gotmpl, functions/render/410-zitadel-provider-config.yaml.gotmpl, functions/render/420-zitadel-project.yaml.gotmpl, functions/render/430-zitadel-oidc-client.yaml.gotmpl, functions/render/440-zitadel-client-secret.yaml.gotmpl
ArgoCD values now include Gateway and OIDC settings. New templates provision Zitadel credentials, provider configuration, project, OIDC client, client Secret labeling, and deletion ordering.
Status reporting and integration validation
functions/render/010-state-status.yaml.gotmpl, functions/render/999-status.yaml.gotmpl, examples/gitopsstacks/zitadel-oidc.yaml, examples/test/mocks/observed-resources/zitadel-oidc/steps/1/zitadel-oidc-client.yaml, tests/test-render/main.k, Makefile, .github/workflows/*
Status publishes the decoded OIDC client ID and includes Zitadel readiness. Examples, mocks, render tests, and CI validation cover the new flow.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🔵 Low · up to ea0d5

Token-backed repository configuration can select the wrong credential type when githubToken.secretPath is empty, causing authentication failures for affected repositories. The change is otherwise mergeable with explicit owner awareness or follow-up to reject empty values.

294-308: 🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick win

Reject an empty githubToken.secretPath.

Lines 294-308 require the field to be present but allow secretPath: "". The ExternalSecret template then takes the GitHub App fallback because it tests this value for truthiness. This can emit empty App references or ignore the token configuration. Add minLength: 1 to githubToken.secretPath.

Evidence: functions/render/240-external-secret-argocd-repo.yaml.gotmpl selects the credential branch from secretPath.

Proposed schema fix
                       secretPath:
                         description: AWS Secrets Manager secret name containing the GitHub token.
                         type: string
+                        minLength: 1
