J'ai créé un projet de chaudière à partir du Divio Django: ( Python 3.6, Django CMS, HTML 5 ) ==)
Vérifier le référentiel renvoie quelques fichiers parmi lesquels sont un docker-compose
et un dockerfile.
Docker-compose:
version: "2"
services:
web:
build: "."
links:
- "db:postgres"
ports:
- "8000:80"
volumes:
- ".:/app:rw"
- "./data:/data:rw"
command: python manage.py runserver 0.0.0.0:80
env_file: .env-local
db:
image: postgres:9.6-Alpine
environment:
POSTGRES_DB: "db"
volumes:
- ".:/app:rw"
Donc localement j'essaie de courir
docker-compose run web
pour démarrer un fichier local Django CMS instance. Cependant, je rencontre l'erreur suivante:

Des idées?
Je peux reproduire l'erreur lors du démarrage du conteneur de manière interactive:
mzh@ale $ docker run -it --rm divio/base:4.14-py3.6-slim-stretch /bin/bash
