multipass-compose

Compose multipass™ virtual machines like a ... charm!

Deprecation warning

Multipass is a buggy and inconvenient project to manage virtual machines with Ubuntu. So this project is now deprecated. Think about using lima/colima instead which is more powerful and truly supported by community.

Install

go install github.com/petr-korobeinikov/multipass-compose/cmd/multipass-compose@latest

2. Start machines up:

3. Check the status:
