Configuring the registry for GCP user-provisioned infrastructure

Configuring a secret for the Image Registry Operator

In addition to the configs.imageregistry.operator.openshift.io and ConfigMap resources, configuration is provided to the Operator by a separate secret resource located within the openshift-image-registry namespace.

The image-registry-private-configuration-user secret provides credentials needed for storage access and management. It overrides the default credentials used by the Operator, if default credentials were found.

For GCS on GCP storage, the secret is expected to contain one key whose value is the contents of a credentials file provided by GCP:

• REGISTRY_STORAGE_GCS_KEYFILE

Procedure

• Create an OKD secret that contains the required keys.

  $ oc create secret generic image-registry-private-configuration-user --from-file=REGISTRY_STORAGE_GCS_KEYFILE=<path_to_keyfile> --namespace openshift-image-registry

Registry storage for GCP with user-provisioned infrastructure

You must set up the storage medium manually and configure the settings in the registry custom resource (CR).

Prerequisites

• To configure registry storage for GCP, you need to provide Registry Operator cloud credentials.

• For GCS on GCP storage, the secret is expected to contain one key whose value is the contents of a credentials file provided by GCP:

  • REGISTRY_STORAGE_GCS_KEYFILE
