Display status information on services.
If no services are provided, all services in the root compose file
will be displayed. Use the --all option to display status of all
services (including dependencies).
$exname offers a few possible columns that can be complete on a charm
level by implementing an \`actions/get-COLNAME\` script.
These are the compose's columns: ${state_inner_cols[@]}.
Usage: status [options] [SERVICE...]
Options:
-h, --help Print this message and quit
-a, --all Display status of all services
(removes all filter, and will add a
'root' first column by default)
-c, --column Column to display, can provide several
separated by commas, or option can be repeated.
(default: ${state_columns_default_msg})
-f, --filter Filter services by a key=value pair,
separated by commas or can be repeated.
(default: --filter root=yes)
