✨Add DeploymentConfig support to registry+v1 bundle renderer #2469

anik120 · 2026-01-29T21:44:25Z

Description

This PR implements Phase 2 of the Deployment Configuration RFC: extending the OLMv1 bundle renderer to apply DeploymentConfig customizations to operator deployments.

Building on the foundation from #2454, this PR enables the renderer to accept and apply deployment configuration when rendering registry+v1 bundles. The implementation follows OLMv0's behavior patterns to ensure compatibility and correctness.

The next PR will wire up the config in the ClusterExtension controller by parsing spec.install.config to convert to DeploymentConfig and thread DeploymentConfig through the controller's render call chain

+// DeploymentConfig is a type alias for v1alpha1.SubscriptionConfig
+// to maintain clear naming in the OLMv1 context while reusing the v0 type.
+type DeploymentConfig = v1alpha1.SubscriptionConfig


I thought we weren't going to use SubscriptionConfig because of the extra selector field?

From the RFC:

NOTE: The v0 SubscriptionConfig struct also has a [Selector](https://github.com/operator-framework/api/blob/master/pkg/operators/v1alpha1/subscription_types.go#L47) field, however it is completely ignored by the v0 controller. According to the comment in the code, it was meant to: Select which pods/ReplicaSets would receive the subscription’s configuration Match pod template labels(similar to Deployment selectors) However, the code that extracts subscription config overrides(pkg/controller/operators/olm/overrides/config.go) extracts all other fields like NodeSelector, Tolerations, Resources and are subsequently applied, but the Selector field is never extracted. OLMv1 will maintain the same behavior—accepting but ignoring this field.

Notice that there's no applySelectorConfig() function, so we're just ignoring that field.

With our wish to reuse v0 SubscriptionConfig for maintainability, we carry over nuance/s into v1. Silently ignoring the selector field being one of them.

We have to remember to document this explicitly for our users everywhere for added clarity.

Pull request overview

Implements Phase 2 of the Deployment Configuration RFC for registry+v1 bundles by threading a DeploymentConfig through the renderer and applying those customizations to CSV-generated Deployment resources (matching OLMv0 behavior), with extensive unit test coverage.

Changes:

Add DeploymentConfig support to render.Options and a new render.WithDeploymentConfig(...) option.
Apply deployment customizations (env/envFrom, volumes, mounts, tolerations, resources, node selector, affinity, annotations) during registry+v1 CSV Deployment generation.
Add/extend unit tests covering option propagation and deployment customization behavior.
