How to change the context path of bitbucket-server in docker mode

[Mohamed MOUFAHIM]

I am looking a way to change the context path of bitbucket-server in docker mode, because I am trying to run it behind a traefik reverse proxy:

I want my bitbucket-server to be served over my.domain.name/bitbucket, and my jira over my.domain.name/jira... etc

I already found a solution for other Atlassian products (jira, servicedesk and confluence) using the reverse proxy setting ATL_TOMCAT_CONTEXTPATH, that environment param is not described in the bitbucket-server docker hub page.
