Add ServiceDefaults.NeutronWsgi, default it to "true" for the currently available OpenStackVersion, and translate it into the neutron.openstack.org/wsgi annotation on the NeutronAPI CR every reconcile. Since AvailableServiceDefaults is keyed by version and only the targeted version's value is applied, existing deployments keep whatever value was computed when they were first initialized until the control plane is moved to a version where this operator sets it to true, so upgrading openstack-operator alone does not flip an existing NeutronAPI from Eventlet to WSGI.

Temporarily points the neutron-operator/api dependency at github.com/karelyatin/neutron-operator@OSPRH-33113-default-master (which adds the NeutronWSGILabel annotation and the WSGI deployment strategy) until that branch merges upstream and this becomes a normal dependency bump.

Review Change Stack

📝 Walkthrough

Summary by CodeRabbit

  • New Features
    • Added support for Neutron WSGI deployments, enabled by default.
    • Added Neutron WSGI service-default configuration to OpenStack version status.
    • Added readiness counts for Neutron RPC and worker processes.
  • Updates
    • Updated default Neutron-related container images to current development images.
    • Added support for selecting WSGI mode during Neutron reconciliation.

Walkthrough

Changes

Neutron WSGI support

Layer / File(s) Summary
Service-default API and initialization
api/core/v1beta1/openstackversion_types.go, api/core/v1beta1/zz_generated.deepcopy.go, api/bases/..., config/crd/bases/..., bindata/crds/crds.yaml, internal/openstack/version.go, api/go.mod
The ServiceDefaults API and CRD schemas add neutronWsgi. Deep-copy logic handles the pointer field. The default initializer sets it to true.
Neutron WSGI reconciliation
internal/openstack/neutron.go, bindata/crds/neutron.openstack.org_neutronapis.yaml
Neutron reconciliation sets NeutronWSGILabel from the service default. NeutronAPIStatus adds RPC and worker readiness counts.
Dependency and image wiring
go.mod, config/operator/*, hack/export_*, zuul.d/projects.yaml
Development dependencies, Neutron-related images, exported image variables, and CI image overrides use the updated development sources.

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

Merge Risk: 🟡 Moderate · up to badad

This PR enables WSGI deployment by default, but the current dependency declarations are rejected by required merge checks and the image defaults include a mutable manager image and an incorrect metadata-service image. The PR is not merge-ready until these references are corrected.

Use the metadata-agent image for the metadata-agent default. The default environment variable passes openstack-neutron-server:master-latest to edpm_neutron_metadata_agent_image, while the export script and dataplane samples use openstack-neutron-metadata-agent-ovn. Align both paths.

Use one immutable, approved Neutron operator manager image. Both changed paths now use the mutable quay.io/ykarel/neutron-operator:v0.0.2 fork tag.

  • config/operator/manager_operator_images.yaml#L39-L39: replace the tag with the approved image digest.
  • hack/export_operator_related_images.sh#L14-L14: export the same approved digest and regenerate the generated manifest.

Remove the forbidden fork replacement before merging. The dependency replacement in go.mod and api/go.mod points to a temporary fork and is rejected by required merge checks. Remove both replacements and pin the approved upstream neutron-operator revision that provides the WSGI API.
