NAME

       buildah-mount - Mount a working container's root filesystem.

SYNOPSIS

       buildah mount [container ...]

DESCRIPTION

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

       If the mount command is invoked without any arguments, the tool will list all of  the  currently  mounted
       containers.

       When  running  in rootless mode, mount runs in a different namespace so that the mounted volume might not
       be accessible from the host when using a driver different than vfs.  To be able to access the file system
       mounted, you might need to create the mount namespace separately as part  of  buildah  unshare.   In  the
       environment  created  with  buildah unshare you can then use buildah mount and have access to the mounted
       file system.

RETURN VALUE

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

OPTIONS

       --json

       Output in JSON format.

EXAMPLE

       buildah mount working-container
       /var/lib/containers/storage/overlay2/f3ac502d97b5681989dff84dfedc8354239bcecbdc2692f9a639f4e080a02364/merged

       buildah mount
       working-container /var/lib/containers/storage/overlay2/f3ac502d97b5681989dff84dfedc8354239bcecbdc2692f9a639f4e080a02364/merged

       If running in rootless mode, you need to do a buildah unshare first to use the mount point.

       $ buildah unshare
       # buildah mount working-container
       /var/lib/containers/storage/overlay/f8cac5cce73e5102ab321cc5b57c0824035b5cb82b6822e3c86ebaff69fefa9c/merged
       # cp foobar  /var/lib/containers/storage/overlay/f8cac5cce73e5102ab321cc5b57c0824035b5cb82b6822e3c86ebaff69fefa9c/merged
       # buildah unmount working-container
       # exit
       $ buildah commit  working-container newimage
