17.4. Copying container images to or from the host

Procedure

1. Copy the registry.access.redhat.com/ubi10/ubi image into your local container storage:

   $ podman run --privileged --rm -v $HOME/.local/share/containers/storage:/var/lib/containers/storage \
   registry.redhat.io/rhel10/skopeo skopeo copy \
   docker://registry.access.redhat.com/ubi10/ubi containers-storage:registry.access.redhat.com/ubi10/ubi

   • The --privileged option disables all security mechanisms. Red Hat recommends only using this option in trusted environments.

   • To avoid disabling security mechanisms, export the images to a tarball or any other path-based image transport and mount them in the Skopeo container:

     • $ podman save --format oci-archive -o oci.tar $IMAGE
     • $ podman run --rm -v oci.tar:/oci.tar registry.redhat.io/rhel10/skopeo copy oci-archive:/oci.tar $DESTINATION

2. Optional: List images in local storage:

   $ podman images
