Which step must you perform before copying an OCI layout to a private registry using skopeo, according to the material?

• A. Login to the private registry using Podman
• B. Login to the private registry using Docker
• C. Install skopeo on the registry host
• D. Authenticate with Kubernetes service account

Answer: (A)

Before copying an OCI layout to a private registry with skopeo, you must authenticate to that registry. The material specifies logging in to the private registry using Podman, because Podman stores the credentials in the registry’s authentication store that skopeo uses when pushing. Without this login, skopeo would receive an authentication error and the push would fail. Installing skopeo on the registry host isn’t required since the operation can be performed from a client machine, and while Docker login can also provide credentials in some setups, the material highlights Podman as the needed step. Authenticating with a Kubernetes service account isn’t related to registry push credentials and wouldn’t enable the push to a private registry.
