Normally we use LXC/LXD, KVM, QEMU, Docker, Vagrant, VirtualBox, VMWare or any other virtualization and containerization software to spawn a VM-like instance locally. Today we’re gonna try multipass, a tool to spawn and orchestrate ubuntu VM. To install multipass, it’s as easy as running these commands:
snap install multipass
ls -al /var/snap/multipass/common/multipass_socket
snap info multipass
To spawn a VM on Ubuntu (for other OSes, see the link above), we can run:
multipass find

To run shell inside newly spawned VM, we can run:
multipass shell groovy-lagomorph
multipass exec groovy-lagomorph — bash
If you need to simulate ssh, according to this issue you can either:
sudo ssh -i /var/snap/multipass/common/data/multipassd/ssh-keys/id_rsa ubuntu@10.204.28.99
# or add ssh key before launch on cloud-init.yaml
ssh_authorized_keys:
— <your_ssh_key># or copy ssh key manually after launch
sudo ssh-copy-id -f -o ‘IdentityFile=/var/snap/multipass/common/data/multipassd/ssh-keys/id_rsa’ -i ~/.ssh/id_rsa.pub ubuntu@10.204.28.99
If to stop/start/delete the VM:
multipass stop groovy-lagomorph
multipass start groovy-lagomorph
multipass delete groovy-lagomorph
multipass purge
What technology used by multipass? it’s QEMU, but maybe it’s different on another platform (it can run on Windows and MacOSX too).
