   -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
+  -d            Dry-run
   -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
