is a directory with a specification file named "` + specConfig + `" and a root

filesystem.

|
|
The specification file includes an args parameter. The args parameter is used
|
|
to specify command(s) that get run when the container is started. To change the
|
|
command(s) that get executed on start, edit the args parameter of the spec.`,
