Docker Compose Django how to deal with DB connection is not ready issue

 DB can be available, but connection takes a while to be ready, if django runs before that without any on hold commands, django will fail to start

Ideal solution will be added the following command to docker-compose.yml

    command: >

      sh -c "python manage.py <wait_for_db_command>&&

             python manage.py migrate &&

             python manage.py runserver 0.0.0.0:8000"

Need also to create a django custom command <wait_for_db_command>
