La Suite numérique is a open source WIP office suite developped by french and german governments to replace proprietary office suite. Theyre self-hosteable but i found the official install instructions unclear to follow, and they have only instructions to install one app at a time. So i've used helmfile and did a one-command install myself.

Have fun

Update : now supports https://dekube.io/ to deploy with docker compose ( https://github.com/baptisterajaut/lasuite-platform/blob/main/docs/compose-deployment.md )
