   - Change the environment variables `TA_USERNAME` and `TA_PASSWORD` to create the initial credentials. 
   - `ELASTIC_PASSWORD` is for the password for Elasticsearch. The environment variable `ELASTIC_USER` is optional, should you want to change the username from the default *elastic*.
 
+### Port collisions
+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.

 ### Elasticsearch

   - Needs to be accessible over the default port `9200`
