How to inject custom web.xml into the Confluence Docker image

[Jacques Clément]

Hi,

I am running Confluence 7.0.X in Docker using the official image

I want to configure <session-timeout> in web.xml with a different value than the default one but I am not sure how to do it. 

I know how to inject a custom server.xml by copying a server.xml.j2 file in /opt/atlassian/etc but the same approach does not seem to work with web.xml.

• If I copy a web.xml.j2 in this directory, the file is ignored;
• If I copy a custom web.xml directly into /opt/atlassian/confluence/confluence/WEB-INF then I get a whole bunch of different errors and Confluence does not even start properly

The latter approach did work until very recently so I suspect something has changed with the way the container starts.

Any thoughts?
