Description: `The run command creates an instance of a container for a bundle. The bundle
|
||
|
|
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. See
|

|
|
"runc spec --help" for more explanation.`,
