If you have a collision on port 8000, best solution is to use dockers HOST_PORT and CONTAINER_PORT distinction: To for example change the interface to port 9000 use 9000:8000 in your docker-compose file.

Should that not be an option, the Tube Archivist container takes these two additional environment variables:

• TA_PORT: To actually change the port where nginx listens, make sure to also change the ports value in your docker-compose file.
• TA_UWSGI_PORT: To change the default uwsgi port 8080 used for container internal networking between uwsgi serving the django application and nginx.

Changing any of these two environment variables will change the files nginx.conf and uwsgi.ini at startup using sed in your container.
