Pull request overview
Adds configurable image-registry support to Roxie deployments, allowing users to deploy from an alternate registry namespace (e.g. quay.io/stackrox-io) while preserving the existing default (quay.io/rhacs-eng). This includes updating operator/bundle image resolution, pull-secret behavior, and registry authentication probing.
Changes:
- Introduces
roxie.imageRegistryconfiguration with validation and defaulting behavior. - Reworks registry credential verification and “registry requires auth” detection to be OCI-distribution compatible (via
go-containerregistrytransport). - Adds bundle-image fallback logic (custom registry → default registry) and expands unit/integration/e2e test coverage around registry overrides.

Wondering if it should also cover sensor. WDYT, could there realistically be any surprises?
In any case, would suggest to have the naming so that it describes what is being deployed. So, either let this function deploy the whole stack or rename to TestCentralDeployWithStackroxIORegistry or something.

I didn't want to increase the duration of the test suite by too much, and I don't really see how we could pull the right images for Central, and the wrong ones for the Secured Cluster. What would your preference be?

Assert the Central image registry.
verifyCentralInstalled only checks that the Central deployment exists. This test can pass if Central still uses the default registry. Assert the Central workload image reference uses quay.io/stackrox-io before completing the test.

That would be unlikely, considering that the operator is from the the right registry, but might be worth checking.

@vladbologa, I checked the propagation path.
Roxie rewrites the operator manager image to quay.io/stackrox-io. It does not set Central image references in the Central custom resource. It also does not inject RELATED_IMAGE_* values in this standard registry path.
The Central image registry is therefore derived by the selected operator image or its embedded configuration. The operator image assertion makes an incorrect Central registry unlikely, but it does not verify the resulting Central workload. The Central image assertion remains useful for this end-to-end test.

Description
Minimal support for deploying from a custom image registry (e.g.
quay.io/stackrox-io) instead of the hardcoded default (quay.io/rhacs-eng).Usage: Via new config field
roxie.imageRegistry, settable via--set roxie.imageRegistry=quay.io/stackrox-io. Not providing this fields results in the previous default (quay.io/rhacs-eng) being used.Notable changes
Operator bundle fallback: When the bundle image doesn't exist on the configured registry (which is the case for upstream
stackrox-iobuilds, and unlikely to be fixed soon),resolveBundleImagefalls back toquay.io/rhacs-eng. This means that roxie will use the CRDs and other info that it reads from the operator CSV fromrhacs-engif it cannot find a bundle in the specified registry.Docker authentication changes: Credential verification rewritten to use
go-containerregistry's transport layer instead of curlingquay.io's proprietary/v2/authendpoint, so it works against any OCI-compliant registry. This is useful because the pre-existing code was hardcoding the quay.io auth URL, but that wouldn't have worked with e.g. Docker Hub.-Pull secrets needed: Had to rewrite the logic around determining whether pull secrets are needed, to properly support both public and private custom registries.
Testing
Confirmed that it deployed an upstream Stackrox image:
