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.

Not immediately obvious to me what this means. Are upper-case characters forbidden?

Indeed, seems to be the case: https://github.com/google/go-containerregistry/blob/main/pkg/name/repository.go#L26

I personally find it non-trivial to understand the different cases here.
Can we maybe keep .KonfluxImagesEnabled() out of the flow (seems like another indirection on instance configs to me).
In the end we need to decide the necessity of pull secrets based on the .BundleImage(), which contains registry+repository, together with the configuration of the cluster (NeedsDefaultRegistryPullSecrets())?

Not really, the bundle image is coming from a different repository than the operator, and is pulled only by roxie. The operator image instead is pulled only on the cluster.
We could have something like:
func (d *Deployer) needsOperatorPullSecrets(ctx context.Context, instance OperatorInstanceConfig) bool {
if !d.repoRequiresAuth(ctx, instance.OperatorImage()) {
return false // public repo, no pull secret needed regardless of cluster
}
// Repo is private, does the cluster already have credentials?
if !d.config.Roxie.UsesCustomRegistry() {
return d.config.Roxie.ClusterType.NeedsDefaultRegistryPullSecrets()
}
return true // cluster never has pre-configured creds for custom registries
}I think this is easier to understand, but has the disadvantage that we're checking if the operator is public or not, even for the default registry. Maybe it's not even a disadvantage: it would be less fragile to check if the repo public, instead of simply assuming.
The check used to be (if you look at line 207 on the original file):
d.useOperatorPullSecrets = instance.KonfluxImagesEnabled() && d.config.Roxie.ClusterType.NeedsPullSecrets()
This was here because quay.io/rhacs-eng/stackrox-operator is public, but quay.io/rhacs-eng/release-operator (Konflux operator) is not.
So the check used to mean: the default Operator image is public, doesn't need pull secrets.

Version based on your latest comment above:
func (d *Deployer) needsOperatorPullSecrets(ctx context.Context, instance OperatorInstanceConfig) bool {
if !d.repoRequiresAuth(ctx, instance.OperatorImage()) {
// Repo is public.
return false
}
// Repo is private.
if d.config.Roxie.UsesCustomRegistry() {
// Cluster never has pre-configured creds for custom registries.
return true
}
// Standard registry. Does the cluster already have credentials?
return d.config.Roxie.ClusterType.NeedsDefaultRegistryPullSecrets()

I actually like that! Putting less assumptions in the code.

Should I also change the similar func (d *Deployer) NeedsPullSecrets() to follow the same pattern? (deployer.go)

How is this supposed to work when different credentials are stored for different registries, e.g. for quay.io/org1 and quay.io/org2? In both cases we would only provide the host-part quay.iotogetCredentialFromHelper`?

I didn't know that was even possible.
My docker config.json and podman auth.json only contain registry entries, like quay.io.
I think Docker doesn't support per repo credentials, but seems that Podman does.
But it feels like an advanced feature, and my initial idea for this PR was to provide a minimal implementation that unblocks the CI migration tasks...

To reduce the noise in the actual t.Run() testing code, what about extracting this into a helper, something like startDummyRegistryServer() or something similar, providing the http status codes as parameters.

Maybe mention in the comment that even in error cases the boolean returend carries meaning (L223).

"reporting that auth is required, alongside an error" was supposed to convey that, should I rephrase it?

How about

Description
Adds 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
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.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.Testing
Confirmed that it deployed an upstream Stackrox image:
