A new technology I found recently was Ubuntu Multipass. It allows you to spin up Ubuntu VMs on demand and is incredibly easy to use. This post will be about installing and basic usage of Ubuntu Multipass.
Multipass can be installed using snap.
sudo snap install multipass
Creating a multipass Ubuntu instance is a single command.
dan@ubuntu-test:~$ multipass launch --name firstinstance
To run a command on an instance you can use the following command.
multipass run vm_name -- command here
So for example you can run bash to get an interactive shell in the instance.
multipass run firstinstance -- bash
An awesome part about multipass is the ability to use cloudinit configurations with these instances. It’s incredibly easy too. The
--cloud-init argument will use your cloud-init configuration during the startup.
multipass launch --name numbertwo --cloud-init clout-init.yml
multipass stop instance_name
multipass start instance_name
multipass delete instance name
To find other images use the following command.
xadlien@swift3x:~$ multipass find

To user one of the other images specify the image name at the end of the launch command.
multipass launch --name dev 21.10
Some great sources for this info can be found here:
I’ve had a lot of issues with multipass recently where it won’t start instances or would just hang. When I CTRL+C out of the delete command and list again it shows the instance as deleted and I was able to launch another instance.
