I am not terribly familiar with Linux or Docker but I was able to follow this guide to get NextCloud working on Docker running on Open Media Vault.
I didn’t use it at first and when I came back to it the login name that I had written down no longer worked. So I deleted the docker and ran it again. I get through everything with no errors (I selected MariaDB option under “storage”) but when I try to log in it does not accept my login. I know a login is created because if I try to use one of the ones from previous sessions it won’t let me. I’ve now done this 4 times with the same results. Any ideas? Thanks so much - I will try to pay it forward.
EDIT
I deleted MariaDB and Nextcloud dockers and ran again. Results are the same. I do see this in the Nextcloud docker when starting up. Later on it does go through the same cycle without errors, if that helps.
