As far as networking, from what I could see the only real change casaos was doing was mapping its dashboard to port 80, but not much more. Is there anything more I should be aware in general?
It depends on how you have things set up. If you’re just doing normal docker compose networking with port forwards then there shouldn’t be much to change, but if you’re doing anything more advanced like macvlan then you might have to set up taps on the host to be able to communicate with the container (not sure if CasaOS handles that automatically).
Same, I don’t let Docker manage volumes for anything. If I need it to be persistent I bind mount it to a subdirectory of the container itself. It makes backups so much easier as well since you can just stop all containers, backup everything in ~/docker or wherever you put all of your compose files and volumes, and then restart them all.
It also means you can go hog wild with
docker system prune -af --volumes
and there’s no risk of losing any of your data.
