Multipass is a cross-platform tool for launching Ubuntu VMs across Linux, Windows, and macOS.

When launching a Multipass VM, user-data can be passed by adding the--cloud-init flag and an appropriate YAML file containing the user-data. For more information about the file and how to construct it, seeour explanatory guide about the user-data cloud-config format.

Create your configuration¶

In this example we will create empty network-config and meta-datafiles, and create a user-data file with a basic cloud-init configuration.

If you have network configuration or metadata to provide, edit thenetwork-config and meta-data files accordingly.

To create the files, run the following commands:

$ touch network-config $ touch meta-data $ cat >user-data <<EOF #cloud-config password: password chpasswd: expire: False ssh_pwauth: True EOF

Launch your instance¶

You can pass the user-data file to Multipass and launch a Bionic instance named test-vm with the following command:

$ multipass launch bionic --name test-vm --cloud-init user-data

Multipass will validate the user-data configuration file before starting the VM. This breaks all cloud-init configuration formats except the user-data cloud-config.
