NAME

6       buildah-mount - Mount a working container's root filesystem.
7
8

SYNOPSIS

10       buildah mount [container ...]
11
12

DESCRIPTION

14       Mounts  the  specified container's root file system in a location which
15       can be accessed from the host, and returns its location.
16
17
18       If the mount command is invoked without any arguments,  the  tool  will
19       list all of the currently mounted containers.
20
21
22       When  running  in rootless mode, mount runs in a different namespace so
23       that the mounted volume might not be  accessible  from  the  host  when
24       using  a driver different than vfs.  To be able to access the file sys‐
25       tem mounted, you might need to create the mount namespace separately as
26       part  of  buildah  unshare.   In  the  environment created with buildah
27       unshare you can then use buildah mount and have access to  the  mounted
28       file system.

RETURN VALUE

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

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