Change

Reconciliation Improvements:

We have added support for direct reconciliation to more resources, with opt-in behavior. The API is unchanged. To use the direct reconciler, add the cnrm.cloud.google.com/reconciler: direct annotation to the corresponding Config Connector object.

Fixed

Bug Fixes:

  • ComposerEnvironment

    • Improved reconciliation, diffing, and update logic for ComposerEnvironment in the direct reconciler. (GitHub PR #12364)
    • Skip the update of a ComposerEnvironment when the state of the underlying Google Cloud Composer environment is not RUNNING. (GitHub PR #12365)
  • ComputeReservation

    • Ignore diff for specificReservation.inUseCount to prevent infinite/unwanted reconciliations.
  • RedisInstance

    • Marked MaintenanceSchedule field as output only to align with GCP's behavior.
  • SQLInstance

    • Fixed legacy fuzzer roundtrip mismatch for PscAutoConnectionPolicyEnabled.
  • CloudFunctions2Function

    • Declared source fields mutable-but-unreadable to avoid spurious diffs.
