SYNOPSIS
skopeo command [options]
DESCRIPTION
skopeo performs operations on container images and registries without requiring a container runtime. It can copy, inspect, delete, and sign images across registries.
The tool is useful for CI/CD pipelines, mirror management, and image inspection without pulling full images.
PARAMETERS
copy src dest
Copy image.inspect image
Show image metadata.list-tags repo
List available tags.delete image
Delete image from registry.sync args
Synchronize repositories.--src-creds user:pass
Source credentials.--dest-creds user:pass
Destination credentials.--authfile file
Authentication file.--override-os os
Override OS.--override-arch arch
Override architecture.
CAVEATS
Registry authentication may be needed. Some operations require write access. Large images take time. Delete may not reclaim space.
HISTORY
skopeo was developed by Red Hat as part of the container tools project alongside podman and buildah. It enables daemonless container image operations, fitting the podman philosophy.
