Another suggestion for you, I highly recommend specifying a version for the docker image you are using for a container, in the compose file. For example, nextcloud:29.0.1. If you just use :latest, it will pull a new version whenever you redeploy which you may not have tested against your setup, and the version upgrade may even be irreversible, as in the case of nextcloud. This will give you a lot more control over your setup. Just don’t forget to update images at reasonable intervals.
