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

Question

I am looking for 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 and want to use my domain for multiple applications (one for each path):

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

My docker swarm stack looks like this:

version: '3'

services:

  bitbucket-server:
    image: atlassian/bitbucket-server:6.7
    deploy:
      labels:
        - "traefik.enable=true"
        - "traefik.http.routers.bitbucket-server.entryPoints=websecure"
        - "traefik.http.routers.bitbucket-server.rule=Host(`my.domain.name`) && PathPrefix(`/bitbucket`)"
        - "traefik.http.services.bitbucket-server.loadbalancer.server.port=7990"
        - "traefik.http.routers.bitbucket-server.tls=true"
        - "traefik.http.routers.bitbucket-server.tls.certresolver=letsencrypt"
        - "traefik.http.routers.bitbucket-server.tls.domains=my.domain.name"
    environment:
      - ATL_PROXY_NAME=traefik.my.domain.name
      - ATL_PROXY_PORT=443
      # next line didn't work ! 
      # - ATL_TOMCAT_CONTEXTPATH=/bitbucket
    volumes:
      - bitbucket_data:/var/atlassian/application-data/bitbucket
    networks:
      - local
      - public-proxy
    labels:

Context path can be configured from bitbucket.properties by adding this line

server.context-path=/bitbucket

In a docker environment, you can mount your bitbucket properties file to your container so it replaces the default one

volumes:
  - YOUR_BITBUCKET_PROPERTIES:<Bitbucket home directory>/shared/bitbucket.properties
