NAME

6       ch-pull2tar - Pull image from a Docker Hub and flatten into tarball
7

SYNOPSIS

9          $ ch-pull2tar IMAGE[:TAG] OUTDIR
10

DESCRIPTION

12       Pull  a  Docker  image named IMAGE[:TAG] from Docker Hub and flatten it
13       into a Charliecloud tarball in directory OUTDIR.
14
15       This runs the following command sequence: docker  pull,  ch-builder2tar
16       but provides less flexibility than the individual commands.
17
18       Sudo privileges are required for docker pull.
19
20       Additional arguments:
21
22          --help print help and exit
23
24          --version
25                 print version and exit
26
