Hi community,
I have a problem after my Confluence Server upgrade from v6.10.0 to v6.15.7.
The update process was ok but the problem is when I restart the Docker stack which contains the running Confluence Server v6.15.7 server then the same server is always showing me the installation page again an again.
I have noted that confluence.cfg.xml file is always updated after any restart.
Docker image:
atlassian/confluence-server:latest@sha256:3ace62fbe3316a8fe1c0114805b11eb4f5f91013d9ec6ce108c6e538cc3978d3
Docker stack file:

Confluence confluence.cfg.xml file:

Your help on this will be very appreciated.
Thanks in advance!
Jose
