Skopeo

Skopeo is a command-line utility designed for managing container images and repositories. Unlike some other tools, Skopeo operates without needing root privileges or a running daemon. It supports both OCI and Docker v2 images, and can interact with various storage mechanisms including registries, local directories, and OCI-layout directories.

Skopeo facilitates operations like copying images between registries, inspecting remote images, deleting images, and syncing repositories for air-gapped deployments. It can handle authentication when necessary, making it a versatile and efficient tool for container image management tasks.
