`multipass launch` command
multipass launch command without any argument will create and start a new instance based on the default image, using a random generated name:
$ multipass launch … Launched: relishing-lionfish
You can then shell into that instance by its name:
$ multipass shell relishing-lionfish … multipass@relishing-lionfish:~$
multipass help launch output explains the available options:
$ multipass help launch Usage: multipass launch [options] [[<remote:>]<image> | <url>] Create and start a new instance. Options: -h, --help Display this help -v, --verbose Increase logging verbosity. Repeat the 'v' in the short option for more detail. Maximum verbosity is obtained with 4 (or more) v's, i.e. -vvvv. -c, --cpus <cpus> Number of CPUs to allocate. Minimum: 1, default: 1. -d, --disk <disk> Disk space to allocate. Positive integers, in bytes, or with K, M, G suffix. Minimum: 512M, default: 5G. -m, --mem <mem> Amount of memory to allocate. Positive integers, in bytes, or with K, M, G suffix. Minimum: 128M, default: 1G. -n, --name <name> Name for the instance. If it is 'primary' (the configured primary instance name), the user's home directory is mounted inside the newly launched instance, in 'Home'. --cloud-init <file> Path to a user-data cloud-init configuration, or '-' for stdin --network <spec> Add a network interface to the instance, where <spec> is in the "key=value,key=value" format, with the following keys available: name: the network to connect to (required), use the networks command for a list of possible values mode: auto|manual (default: auto) mac: hardware address (default: random). You can also use a shortcut of "<name>" to mean "name=<name>". Arguments: image Optional image to launch. If omitted, then the default Ubuntu LTS will be used. <remote> can be either ‘release’ or ‘daily‘. If <remote> is omitted, ‘release’ will be used. <image> can be a partial image hash or an Ubuntu release version, codename or alias. <url> is a custom image URL that is in http://, https://, or file:// format.
The only, optional, positional argument is the image to launch an instance from. See the
multipass find documentation for information on what images are available. It’s also possible to provide a full URL to the image (use
file:// for an image available on the host running
You can change the resources made available to the instance by passing any of
--mem options, allowing for more CPU cores, disk space or RAM, respectively.
If you want your instance to have a name of your choice, use
--name. It has to be unique, two instances can’t share the same name.
--network option allows launching instances with additional network interfaces [since version 1.6.0].
