Daniel J Walsh 6979d140f1 Add podman image mount
There are many use cases where you want to just mount an image
without creating a container on it. For example you might want
to just examine the content in an image after you pull it for
security analysys.  Or you might want to just use the executables
on the image without running it in a container.

The image is mounted readonly since we do not want people changing
images.

NAME

podman-image-mount - Mount an image's root filesystem

SYNOPSIS

podman image mount [options] [image ...]

DESCRIPTION

Mounts the specified images' root file system in a location which can be accessed from the host, and returns its location.

If you execute the command without any arguments, Podman will list all of the currently mounted images.

Rootless mode only supports mounting VFS driver, unless you enter the user namespace via the podman unshare command. All other storage drivers will fail to mount.

RETURN VALUE

The location of the mounted file system. On error an empty string and errno is returned.

OPTIONS

--all, -a

Mount all images.

--format=format

Print the mounted images in specified format (json).

EXAMPLE
