Docker Compose not updating content
I have some containers running with docker compose but I just can’t find a way to properly update my containers without having to remove it and create it again. I have a Python app and I can successfully deploy code changes and those get applied, but if I add files like css, js or images those don’t get to the container.
I have tried with this command, even though in the console it logs the messages as expected (rebuild it with no cache) I had no no success:
docker-compose build --no-cache web && docker-compose up -d
The only command that works for me is to remove it like this:
docker stop $(docker ps -a -q) && docker rm $(docker ps -a -q) && docker rmi $(docker images -a -q)
And then build and deploy:
docker-compose build && docker-compose up -d
Here’s my docker-compose.yml:
web: restart: always build: ./web expose: - "8000" links: - postgres:postgres - redis volumes: - /usr/src/app/donare/static env_file: .env command: /usr/local/bin/gunicorn -w 2 -b :8000 --limit-request-line 16384 donare.app:app nginx: restart: always build: ./nginx/ ports: - "80:80" volumes: - /www/static volumes_from: - web links: - web:web data: restart: always image: postgres:latest volumes: - /var/lib/postgresql command: "true" postgres: restart: always build: . dockerfile: dockerfile-postgres volumes_from: - data ports: - "5432:5432" redis: image: redis celery: build: ./web command: celery worker --app=donare.tasks.tasks volumes: - .:/code links: - postgres - redis
One Solution collect form web for “Docker Compose not updating content”
Your Docker Compose file shows that you have a named volume in the
web container. Is
/usr/src/app/donare/static where your css, js, and images are supposed to come from on your Docker host? If so, perhaps you meant to mount
/usr/src/app/donare/static into your container, not create a volume with that name? Or, if the css, js, and images are built into your image, then you should probably just remove that named volume.
Assuming your css, js, and images are at the path
/usr/src/app/donare/static in the container, then what’s happening is that because you have a named volume there, the first time you run the
web service, a volume is being created and initialized with the contents at that path. Every time you do your
up, that same initial volume is being mounted at the path with your old files. When you
rm, the volume is implicitly being deleted too, causing it to be recreated and initialized with fresh files.
