Skopeo - Work with remote images registries - retrieving information, images, signing content

skopeo is a command line utility that performs various operations on container images and image repositories. skopeo can work with OCI images as well as the original Docker v2 images. Skopeo works with API V2 container image registries such as docker.io and quay.io registries, private registries, local directories and local OCI-layout directories.

skopeo can perform operations which consist of:

• Copying an image from and to various storage mechanisms. For example you can copy images from one registry to another, without requiring privilege.
• Inspecting a remote image showing its properties including its layers, without requiring you to pull the image to the host.
• Deleting an image from an image repository.
• Syncing an external image repository to an internal registry for air-gapped deployments.
• When required by the repository, skopeo can pass the appropriate credentials and certificates for authentication.
