See  Docker Environment Variables  for details on which settings can be configured. If you want to use a  .env  file, you can use the provided  .env.dist  file and copy it to  .env . That way it will be picked up by Docker-Compose automatically and not overwritten during updates. Zammad runs on port  8080  by default. If you want to use another port, you can set it via the variable  NGINX_EXPOSE_PORT .
