I have been able to move my Jira/Bitbucket/Confluence from LXC containers into the prebuilt docker containers and have scripts that handle the upgrades for Jira and Confluence. Bitbucket seems to have issues with consuming an external volume. I've tried using both podman and docker to run the containers but have not been successful. There is a crash that occurs when launching the springboot application. I use an external database and have been able to prove that this occurs when setting up a new installation with a dedicated volume as specified in the documentation. This has made it very challenging to handle upgrades as I have to copy the data to each new container volume as a container is created.
