Summary

This pull request introduces comprehensive support for orchestrating OpenStack Designate DNS Zones via a new custom resource controller (DNSZone) in the OpenStack Resource Controller (ORC) project. By enabling declarative lifecycle management of PRIMARY and SECONDARY DNS zones directly from Kubernetes, this change streamlines cloud infrastructure automation, ensuring consistent DNS provisioning and secure importing of pre-existing external DNS zones.

Changes

API Definitions & Schema Validation

  • Defined the DNSZone Custom Resource Definition (CRD) in api/v1alpha1/dnszone_types.go, covering spec, filter, and status definitions for primary and secondary zones, with the Type field restricted to PRIMARY and SECONDARY via enum validation.
  • Enforced strict schema-level, CEL, and immutability validations (e.g., verifying zone names end with a period, TTL range constraints, Email field presence verification for PRIMARY type zones and rejection for SECONDARY type zones, verifying PRIMARY type with masters specified is rejected, and immutability of Name and Type fields).
  • Integrated the masters field for secondary zones, including validation rules and a MaxItems: 32 constraint on status tracking to prevent kubeapilinter warnings.
  • Regenerated CRD schemas, deepcopy files, and OpenAPI definitions (make generate and make manifests).

OpenStack Client & Scope Integration

  • Created the OpenStack Designate DNS client interface and implementation in internal/osclients/dnszone.go mapped directly to Gophercloud's v2 zones package.
  • Integrated NewDNSZoneClient into the global Scope interface, providing provider logic and generated Mock clients for testing.

Controller & Actuator Implementation

  • Developed the dnsZoneActuator under internal/controllers/dnszone/actuator.go to support generic controller actions for managed creation, updates, deletes, and unmanaged zone adoptions/imports.
  • Created dnsZoneStatusWriter to reconcile observed Designate statuses (e.g. mapping ACTIVE to Available, PENDING to progress polling, and ERROR to terminal failures).
  • Registered the controller in cmd/manager/main.go and implemented standard secret credentials watches.

Verification & Testing

  • Added unit tests for the actuator and status writer using GoMock in actuator_test.go and status_test.go.
  • Implemented API validation integration tests under test/apivalidations/dnszone_test.go.
  • Enabled the Designate plugin in DevStack within the GitHub Actions E2E workflow (.github/workflows/e2e.yaml).
  • Developed E2E KUTTL test suites for full primary zone lifecycles, unmanaged imports, and invalid input terminal errors.

Documentation & Examples

  • Provided declarative manifest examples for primary and imported DNS zones under examples/dnszone/.
  • Written a detailed user guide in website/docs/user-guide/dnszone.md and integrated it into the website's mkdocs.yml navigation.
  • Regenerated the website CRD API reference docs using make -C website crd_ref_docs.

Implementation Notes

  • Designate Client Adaptations: Directly mapped the Gophercloud package zones.Zone resource to match Designate APIs. Implemented ToZoneUpdateMap() directly to map flat updates, omitting the read-only Name field in updates.
  • Asynchronous Requeueing: Leveraged progress.WaitingOnOpenStack in the status writer to support seamless async polling when zones reside in a PENDING state on the openstack side.
  • CEL Typo & Escaping Fixes: Solved syntax issues where certain editor auto-formatting converted regular CEL quotes into smart quotes, causing EnvTest startup validation failures.
  • Conflict Handling: Handled duplicate creation conflicts (HTTP 409) during creation by returning a terminal error with the UnrecoverableError reason code.

Testing

  • Unit Testing: Ran local controller tests via go test ./internal/controllers/dnszone/... and verified 100% of the tests passed with zero linter errors.
  • API Validation: Verified schema-level checks and immutability CEL rules through go test ./test/apivalidations/....
  • E2E Testing: Executed the complete KUTTL test suites locally and in GitHub Actions CI against active DevStack instances with the Designate services enabled.

- Updated internal/controllers/dnszone/actuator.go to utilize the renamed DNSZoneClient interface methods.
- Resolved a CEL validation rule typo in api/v1alpha1/dnszone_types.go where a curly smart double-quote character was incorrectly used instead of single quotes, which prevented Kubernetes control plane from loading the CustomResourceDefinition during local EnvTest runs.
- Regenerated mock files and client implementations using make generate.
- Verified that all unit tests, linters, and EnvTest suites run and pass cleanly.

Detailed description:
- Overwrote the scaffolded 'dnszone-import' E2E KUTTL test suite to implement the unmanaged DNSZone import scenario by ID.
- Added a script in step 00 of 'dnszone-import' to pre-create a zone in Designate using the 'openstack' CLI and dynamically write the unmanaged DNSZone CR configured with the pre-created zone's ID in '01-import-resource.yaml'.
- Implemented step 01 to assert successful import and observed state population on status.resource.
- Implemented step 02 to delete the CR and assert that the Kubernetes object is deleted, while verifying with the 'openstack' CLI that the actual zone still exists in Designate, and finally cleaning it up to prevent resource leaks.
- Created 'internal/controllers/dnszone/tests/dnszone-errors/' KUTTL test suite to verify importing a non-existent zone ID.
- Implemented assertion in 'dnszone-errors' verifying the CR transitions to a terminal error state with 'UnrecoverableError' reason and 'referenced resource does not exist in OpenStack' message.
