Improving LXC resource distribution #6

fnetX commented 2023年02月19日 21:53:46 +01:00

Currently, our LXC config uses hard upper limits for each container, which might not be very efficient, and indeed, there are currently unused resources in our systems.

A more efficient approach could be to do minimum guarantees (for example as suggested here), and use some spare resources for everyone to take.

Any opinions on that?

In my daily job I use LXCs by Proxmox VE. May be I can help on that topic.

Do we have some sort of controller? Or we have our own framework to handle LXCs?

We have wrapper scripts about plain LXC commands in https://codeberg.org/Codeberg-Infrastructure/scripted-configuration/src/branch/main

But we basically just use plain lxc-create with a custom config file.
