Closes #1992

Summary by CodeRabbit

  • New Features
    • Added optional OIDC authentication configuration for Dawarich deployments, including provider details, redirect settings, identity-field mappings, and login presentation options. OIDC remains disabled by default.
    • Supports supplying client credentials directly or referencing an existing Kubernetes Secret; when credentials are supplied directly, the chart creates a Secret.
    • OIDC settings are applied to web and worker workloads when enabled.
  • Documentation
    • Deployment notes now show the configured OIDC issuer, client ID, and client-secret reference when OIDC is enabled.

Walkthrough

The Dawarich Helm chart adds configurable OIDC values, validation, environment variables, and client-secret handling. Helm tests cover rendered OIDC settings, secret configurations, and invalid values. Chart metadata records the OIDC addition and updates the chart version.

Full details: Title check

Explanation

The title "feat(dawarich): add OIDC authentication configuration support" matches the main change in the changeset. The PR adds OIDC values, schema entries, helper validation, environment variable rendering, a conditional Secret template, NOTES output, and tests for the Dawarich chart. The linked objectives (issue #1992) also ask for a way to configure Dawarich OIDC authentication in the chart, so the title reflects the primary intent.

Full details: Linked Issues check

Explanation

Directly linked issue #1992 requests a chart-supported way to configure Dawarich OIDC user authentication. The issue states that the required OIDC environment variables are blocked by the chart validation helper and that no alternative configuration exists.

Evidence at the reviewed head (whole-PR diff from merge base 6b9aab9):

  • _helpers.tpl adds dawarich.oidcSecretName. It returns oidc.existingSecret or a fullname-derived name ending in -oidc.
  • _helpers.tpl validation requires oidc.issuer and oidc.clientId when oidc.enabled is true. It requires exactly one of oidc.clientSecret or oidc.existingSecret. It rejects OIDC settings when oidc.enabled is false.
  • _helpers.tpl dawarich.environment always renders OIDC_ENABLED. When enabled, it renders OIDC_ISSUER, OIDC_CLIENT_ID, and OIDC_CLIENT_SECRET (secretKeyRef to the selected Secret and oidc.clientSecretKey). It conditionally renders OIDC_REDIRECT_URI, OIDC_SCOPE, OIDC_RESPONSE_TYPE, OIDC_UID_FIELD, OIDC_NAME_FIELD, OIDC_EMAIL_FIELD, OIDC_ICON_URL, OIDC_BUTTON_TITLE, OIDC_PROMPT, and OIDC_AUTO_LOGIN.
  • The prior review reports values.yaml, values.schema.json, templates/oidc-secret.yaml, NOTES.txt, and automated Helm tests (tests/oidc_test.yaml, tests/validation_test.yaml). I confirmed the helper changes in the diff. I did not run helm template or the Helm unit tests.

The extraEnv rule that rejects PG-prefixed and other managed names is unchanged. The new oidc values replace the need to pass OIDC_* variables through extraEnv, so this rule does not block the requested capability.

Unresolved uncertainty: the raw summary states that buttonTitle, prompt, and autoLogin are each declared twice in values.schema.json. The file read was truncated at 16000 bytes, so I could not verify this. Duplicate JSON keys do not remove the configuration path, so this does not change the coding-requirement result. It is a schema-quality concern to check.

Full details: Out of Scope Changes check

Explanation

Each changed area supports the OIDC objective of issue #1992:

  • values.yaml and values.schema.json: new oidc section, disabled by default, with schema validation.
  • _helpers.tpl: OIDC secret name helper, OIDC validation, and OIDC environment rendering. The diff confirms these changes.
  • templates/oidc-secret.yaml: release Secret for an inline clientSecret.
  • templates/NOTES.txt: OIDC usage notes, rendered only when enabled.
  • ci/oidc-values.yaml and ci/external-secrets-values.yaml: CI values for the new paths.
  • tests/oidc_test.yaml and tests/validation_test.yaml: tests for the new behavior.
  • Chart.yaml: version bump from 1.0.10 to 1.0.11 and an Artifact Hub entry. This is release metadata for the chart change.

I found no change without a connection to OIDC configuration. The unverified duplicate schema keys noted in the linked-issue assessment sit inside the OIDC schema block, so they do not indicate an unrelated change.

Full details: Docstring Coverage

Explanation

No eligible functions found in the changed files. Skipping docstring coverage check. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 0 functions across 0 files.

Allow the OIDC routes through the proxy when OIDC is enabled.

The proxy returns 403 for both /users/auth/openid_connect and its configured callback, so OIDC login cannot complete. Allow only these OIDC routes while preserving the other authentication and registration denials.

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.

Move the OIDC validation into the schema.

The oidc schema types each property, but the template fail guards in _helpers.tpl enforce the conditional rules. These rules can be written as JSON Schema if/then constraints. Schema validation runs before rendering and gives earlier errors. Consider these constraints for the rules below:

  • When enabled is true, require a non-empty issuer and clientId.
  • When enabled is false, require empty issuer, clientId, clientSecret and existingSecret.

Keep the template guard for the mutual-exclusion and the "at least one secret" rules if the schema cannot express the whitespace trim behavior.

entry that creates the Secret named dawarich-eso-oidc with a clientSecret key,
matching the existing admin and identity entry format. Keep oidc.existingSecret
aligned with that Secret name.

Review comments at @charts/dawarich/templates/_helpers.tpl:
- Around line 52-53: Align OIDC secret handling across the validation checks,
`oidc-secret.yaml`, and `dawarich.oidcSecretName`: treat whitespace-only
`existingSecret` and `clientSecret` values as absent by using trimmed values
consistently. Ensure the helper’s Secret name fallback and the template creation
condition use the same trimmed-value semantics, preventing a pod from
referencing a whitespace-named Secret that was not created.

Add OIDC assertions for the worker.

This test checks only the web container. A worker-only omission could pass the current tests.

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.

Remove the duplicate buttonTitle, prompt, and autoLogin keys.

Lines 1056-1064 repeat keys already declared at lines 1047-1055. Duplicate JSON object keys are invalid under strict linting (Biome noDuplicateObjectKeys reports them). Parsers keep the last value, so behavior is unchanged today. Remove the second set.
