23 is a directory with a specification file named "` + specConfig + `" and a root
24 filesystem.
25
26 The specification file includes an args parameter. The args parameter is used
27 to specify command(s) that get run when the container is started. To change the
28 command(s) that get executed on start, edit the args parameter of the spec.`,
