Unable to Access GCR Private Registry Using Service Account Credentials #1189

Description

@cwillhelm-mirantis

What steps did you take and what happened:

I'm trying to get starboard to scan images in a private GCR registry, and I've successfully created the secrets and service account associations with the credentials.

To confirm my credentials work, I used:

cat gcp-starboard-key.json | docker login -u _json_key --password-stdin https://gcr.io/

With gcp-starboard-key.json being GCP service account credentials.

I then created the docker-registry secret in kubernetes using this command:

kubectl create secret docker-registry starboard-gcp-access --namespace default --docker-server=gcr.io --docker-username=_json_key --docker-password="$(cat ~/Downloads/gcp-starboard-key.json)" --docker-email="gcr-starboard-access@project.iam.gserviceaccount.com"

I associated the secret with the service accounts by adding the imagePullSecret: starboard-gcp-access.

In the starboard-operator logs, I see this:

"error":"reading .dockerconfigjson field of \"default/starboard-gcp-access\" secret: expected username and password concatenated with a colon (:)","stacktrace":"sigs.k8s.io/controller-runtime/pkg/internal/controller.(*Controller).processNextWorkItem\n\t/home/runner/go/pkg/mod/sigs.k8s.io/controller-runtime@v0.11.2/pkg/internal/controller/controller.go:266\nsigs.k8s.io/controller-runtime/pkg/internal/controller.(*Controller).Start.func2.2\n\t/home/runner/go/pkg/mod/sigs.k8s.io/controller-runtime@v0.11.2/pkg/internal/controller/controller.go:227"}

What did you expect to happen:

Starboard to pull the image and scan for VulnerabilityReport

Anything else you would like to add:

The cluster is running the latest version of GKE Autopilot (1.22.6).
