I don't have many machines but about 40 containers. I used docker compose. Then I've found Trillium Notes for the documenting part. I have the client on my mac that syncs to the trillium container on my server that way I can always have access if something happens and the server is down or I need it offline. One thing I love about it is that I've set it so all pages are read only by default. This makes it work for me more like a wiki and I don't accidentally overwrite something. The discipline to keep it updated?..... biggest challenge.
