help="Usage: $(basename $0) [-fch] [-l label] [-e options] image [container]
|
|
Create and start a container from a local image, and assign it the given name.
|
|
|
|
If second argument is omitted, defaults to assigning the container the same name
|
|
as the image.
|
|
|
|
Options:
|
|
-f Force overwrite if a container with the given name already exists
|
|
-c Configure the container with deploy options stored in the image
|
|
metadata. By default, uses the metadata tag labeled 'config_default'
|
|
-l [label] Label from which to get the deploy options. Automatically sets -c
|
|
-e [options] Extra deploy options to assign to the container. If -e and -c are
|
|
both used, options from image metadata and command line are combined
|
|
-h Display this help and exit"
