Which Podman command loads an image from a tar file?

• A. sudo podman import FILE_NAME
• B. sudo podman load -i FILE_NAME
• C. sudo podman load FILE_NAME -i
• D. sudo podman pull FILE_NAME

Answer: (B)

Restoring a pre-built image from a tarball into your local Podman image store is done with the load command using the input option. The correct approach is to run the command that specifies the tar file to read with -i, which tells Podman to load the image contained in that tarball into the local image registry. In other words, podman load -i FILE_NAME reads the tar file FILE_NAME and reconstructs the image so you can use it locally. The other options don’t fit this purpose: import would create an image from a filesystem tar, not from a saved image tarball; pull expects to fetch an image from a registry rather than read a local tar; and the syntax in the incorrect variant isn’t how Podman expects to receive the tar input.
