This is just changing the variable used in defaulting logic to the new consolidated container image from s2i.

So far, this is just to test the approach. We may want to move all defaults to s2i in openstack-operator.

Depends-On: openstack-k8s-operators/watcher-operator#437

📝 Walkthrough

Summary by CodeRabbit

  • Chores
    • Consolidated Watcher image configuration into a single base image setting.
    • Simplified image configuration by replacing separate API, Applier, and Decision Engine image variables with one shared value.
    • Updated Watcher deployments and status reporting to consistently use the unified base image across all components.
    • Aligned functional validation with the consolidated image configuration.

Walkthrough

The Watcher API, Applier, and Decision Engine now use one Watcher base-image variable. Version initialization maps this value to all three service image defaults. Functional tests expect the unified image.

Changes

Watcher image configuration

Layer / File(s) Summary
Watcher base-image configuration
config/operator/default_images.yaml, hack/export_related_images.sh
The three Watcher image settings and exported variables are replaced by RELATED_IMAGE_WATCHER_BASE_IMAGE_URL_DEFAULT, which points to openstack-watcher-base:master-latest.
Watcher image default mapping
internal/openstack/version.go
RELATED_IMAGE_WATCHER_BASE_IMAGE_URL_DEFAULT is assigned to the Watcher API, Applier, and Decision Engine image defaults when present.
Watcher image test expectations
test/functional/ctlplane/openstackoperator_controller_test.go
Functional-test expectations use the unified Watcher base image for the Decision Engine, API, Applier, and container-image status fields.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to 6d448

The PR changes Watcher services to use the shared s2i container image. Tests could assert the API and Applier image values more precisely, but no actionable merge-blocking risk remains.

Comment thread config/operator/default_images.yaml
Watcher is moving to a single container image to all the services. This
patch is modifying the defaulting logic and environment variable used to
set the default images in OpenStackVersion for the Watcher services.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Assert the shared image for all Watcher services.

At Line 2128 and Line 2314, the tests compare the shared value only for Watcher.Spec.DecisionEngineContainerImageURL. They check Watcher.Spec.APIContainerImageURL and Watcher.Spec.ApplierContainerImageURL only for non-nil values. Add equality assertions for all three fields in both tests. Otherwise, an incorrect API or Applier image can pass.

Based on the unified Watcher image objective and the internal/openstack/version.go mapping.

Also applies to: 2314-2314
