Docker, Docker-Compose, Django, Postgres
После выполнения команды docker-compose up с нуля ситуация такая:
- Строится контейнер из Dockerfile, тут всё норм.
- Потом, когда строится БД, то postgres пытается слушать по адресу 0.0.0.0.
- БД падает, на половине запуска сервера всё заканчивается и сервер не поднимается.
Помогите пожалуйста, я не понимаю в чём проблема.
