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.

dhcp-agent have some issues so will be switched in follow up.

📝 Summary

Summary by CodeRabbit

  • New Features

    • Added Neutron WSGI configuration support through OpenStack version service defaults.
    • Neutron deployments now apply WSGI settings automatically when configured.
    • Added readiness counts for Neutron RPC and worker processes.
    • Added support for managing minor updates through defined target stages.
  • Updates

    • Updated default Neutron-related container images.
    • Refreshed the Neutron operator image.
    • Excluded a known router rescheduling test from the automated test suite.

Walkthrough

The change adds Neutron WSGI configuration to the OpenStackVersion API, enables it by default, and applies it during Neutron reconciliation. It also adds minor-update stage helpers, readiness fields, updated images, a dependency update, and a Tempest exclusion.

Changes

Neutron operator updates

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
The ServiceDefaults API and CRD schemas include NeutronWsgi. Deep-copy logic preserves the pointer field. The default sets Neutron WSGI to enabled.
Minor-update stage contracts and resolution
api/core/v1beta1/openstackversion_types.go
The API defines ordered minor-update stages, validates target annotations, limits reconciliation stages, and resolves completed stages from status conditions.
Neutron WSGI reconciliation
internal/openstack/neutron.go, bindata/crds/neutron.openstack.org_neutronapis.yaml
Neutron reconciliation sets the NeutronWSGILabel annotation from the service default. The NeutronAPI status schema adds RPC and worker readiness counts.
Dependency and image wiring
api/go.mod, go.mod, config/operator/default_images.yaml, config/operator/manager_operator_images.yaml, hack/export_related_images.sh, hack/export_operator_related_images.sh
The Neutron API dependency and manager image digest are updated. Neutron-related default and exported images now use the specified master-latest images.
Tempest exclusion configuration
zuul.d/jobs.yaml
The multinode Tempest job excludes the router rescheduling test.

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

Merge Risk: ⚪ Minimal · up to 827c4

This change enables Neutron WSGI defaults for applicable OpenStack versions while preserving existing deployments’ prior setting until version transition. No concrete unresolved correctness, deployment, or data-safety risk is identified.
