  • Nothing you show here tries to run migrations. What's the actual command you're running, and where are you running it from? Also see [How do you perform Django database migrations when using Docker-Compose?](https://stackoverflow.com/questions/33992867/how-do-you-perform-django-database-migrations-when-using-docker-compose) – David Maze Jul 20 '22 at 10:17
