Summary

Adds Helm values for API service selection and core controller selection so deployments no longer need to rely on hard-coded default flags or duplicate selection flags in extraArgs. Explicit service/controller selections are list-only, legacy selection flags in extraArgs still suppress generated defaults, and the chart keeps the controller group default at all so plugin controllers remain active by default.

Changes

  • Added API and controller Helm helper logic that emits group defaults, joins explicit list values, and rejects non-list explicit selections before defaults can mask invalid falsy values.
  • Aligned helper include indentation in the API and controller deployments with the chart's existing nindent ... | trim pattern so generated args render without an extra blank line.
  • Updated chart defaults and generated README entries for list-only api.services and core.controller.controllers, with core.controller.controllerGroup defaulting to all.
  • Rephrased the Helm values comments so helm-docs parses the new rows instead of treating embedded CLI flags as comment delimiters, and kept the README template compatible with current main.
  • Updated Helm rendering tests for default/configured group behavior, list-only validation, invalid falsy selections, and legacy extraArgs suppression.
  • Updated the Authentik umbrella values assertion to use the new selection values instead of API extraArgs.
  • Merged current origin/main into the branch so the PR is no longer dirty; head is ded4dffc1 with 8 commits over origin/main.

📝 Walkthrough

Walkthrough

The Helm chart now uses declarative API service and core controller selection. Explicit lists take precedence over groups. Legacy selection flags remain supported. Invalid or missing selections fail template rendering.

Changes

Service and controller selection

Layer / File(s) Summary
Selection values and configuration contracts
k8s/helm/values.yaml, k8s/helm/README.md, contrib/auth/authentik/helm/values.yaml, tests/auth_idp/static/test_authentik_kubernetes_demo.py
Declarative service and controller groups now use explicit defaults. API services and core controllers require lists. Authentik uses declarative serviceGroup and controllerGroup fields.
API service argument rendering
k8s/helm/templates/api/_helpers.tpl, k8s/helm/templates/api/api-deployment.yaml, tests/unit/test_helm_clickhouse.py
The API renders configured services or service groups. It rejects invalid or missing selections. Legacy selection arguments take precedence.
Core controller argument rendering
k8s/helm/templates/core/_helpers.tpl, k8s/helm/templates/core/controller-deployment.yaml, tests/unit/test_helm_clickhouse.py
The controller renders configured controllers or controller groups. It rejects invalid or missing selections. Legacy controller arguments take precedence.

Overall, looks good! Added some nits in places that don't cover the entire thing...please generalize for my lazy commenting.

I cannot say if it is truly necessary to support the legacy args or not, so I have to assume it's a good and generous idea.

106-135: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Cover both legacy flag families.

The tests cover --service-group and --controller-group, but the helpers also support --services and --controllers. Add one suppression test for each explicit-list flag, including its assigned-value form.

Also applies to: 138-165, 202-210
