Create a Django admin account inside a Docker container

Assuming that your Django container is already running under Docker, find out what it’s ‘Container ID’ is.

$ docker ps
CONTAINER ID IMAGE ...
fb3aabc8e123 django-web ...

In the above example the Container ID is fb3aabc8e123.

Now you can easily execute commands inside that container.

$ docker exec -it fb3aabc8e123 sh

The ‘-it’ option executes the command in an Interactive Terminal.

The ‘sh’ at the end of the command is the program to run, in this case it the system shell program. You could use ‘bash’ on a Linux machine if that’s your preference.

Now that you have a shell running in the Django container, you can run the command to create the admin user account.

# python ./manage.py createsuperuser

Django migrations inside a Docker container

The easiest way to have Django run a migration inside a Docker container is to get Docker to run a new container to perform the task.

Using ‘run’ instead of ‘exec’ works if there is a start-up script like entrypoint.sh that prevents the container from starting until the migration has been completed (egg-chicken-egg).

E.g. I have a Django app called ‘web’ defined in docker-compose.yml , my terminal’s current working directory is the Django container folder where manage.py is resident.

$ docker compose run web ./manage.py migrate

This probably works similarly with Podman, I just haven’t tried it yet to verify.
