I have Atlassian Jira and Confluence Docker server which are redelivered monthly with updated containers.
The home directory is retained through iterations, but I have recognized that the app-links need to be recreated on each iteration; So I speculate they are not retained in the home directory. They are also not found in volatile memory, as they are retained during an on/of cycle, so I speculate that they are retained in the installation directory?
In any case I need to retain these files to automate this and reduce my Docker server maintenance period after upgrades, and am looking for where they are located on Jira and Confluence servers.
