Now do LXC 😉
Discussion
I think Proxmox uses LXC right? But yeah I have not gone down that rabbit hole
Yes but Proxmox is not required. LXC will install on whatever Linux distribution you run on your laptop. Much like Docker actually.
I'm a big fan of docker compose for easy portability and config. Is there a similar flow with LXC?
No it's really more like running multiple systems in parallel sharing the same kernel and hardware resources. Docker is the best tool for application distribution in reproducible environments.
