Ensure osp-secret manifests include a per-cluster Fernet KEK before oc apply. Look up the live secret in the namespace declared on the manifest (for example openstack2 in multi-namespace scenarios), reuse an existing cluster key when present, and generate a new key when needed.

Review Change Stack

Warning

Review limit reached

@Deydra71, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 33 minutes

Limit details: You’ve used the included review currently available.

You've used all free OSS reviews for now. Wait for the free limit to reset to keep reviewing this public repository.

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits within each organization.

For paid Pro and Pro+ reviews, CodeRabbit uses a developer's included PR review attempts over the past 7 days to set the current hourly allowance. At typical activity levels, the full plan allowance applies. Higher sustained activity can lower the allowance until earlier attempts leave the 7-day window.

Please refer docs for additional details.

📝 Walkthrough

Summary by CodeRabbit

  • New Features

    • Deployment manifests now ensure the required BarbicanSimpleCryptoKEK key is present in osp-secret.
    • Existing cluster or manifest keys are preserved; a new secure key is generated only when needed.
    • Added tooling to inspect and update osp-secret values in YAML manifests.
  • Documentation

    • Added guidance describing secret key handling during control-plane deployments.
  • Tests

    • Added comprehensive coverage for secret discovery, decoding, updates, namespace handling, and command-line results.

Walkthrough

The role now manages BarbicanSimpleCryptoKEK in generated osp-secret manifests. It reuses a cluster or manifest key when available and generates a Fernet key otherwise. A Python helper provides manifest operations and CLI tests cover the behavior.

Changes

OSP Secret Key Management

Layer / File(s) Summary
Manifest helper and CLI
roles/kustomize_deploy/files/osp_secret_manifest.py, tests/unit/roles/test_osp_secret_manifest.py
The helper locates osp-secret, reads namespaces and decoded keys, updates changed values with base64 encoding, and exposes has, get, get-namespace, and set commands. Tests cover helper functions, CLI statuses, namespace output, and persisted updates.
Deployment key selection and injection
roles/kustomize_deploy/tasks/execute_step.yml, roles/kustomize_deploy/tasks/inject_osp_secret_keys.yml, roles/kustomize_deploy/README.md
The deployment tasks inspect the generated manifest, query the live secret, preserve an existing key, generate a Fernet key when no key exists, and inject the selected key before applying the manifest. Documentation describes this sequence.

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

Merge Risk: 🟠 High · up to 1e174

The deploy-time secret injection can expose Fernet keys, reuse a prior manifest’s key for another cluster, or replace a live cluster key after a lookup failure. These security and data-protection risks make the current head unsafe to merge until addressed.
