Docker Portainer Build Invalid Reference Format
Docker error on portainer Build invalid reference format#
I got this error when trying to deploy a stack. I set the
docker-compose.yml file to use and link to the git repo I get this error:
Build invalid reference format
So my first thought was that the
docker-compose version was too high
3.7, but that wasn’t the problem.
The problem was that this docker compose was structured for development - ie. it relied on the code being local and building the image.
When you deploy to production there is not a bound mount volume to build. There shoould only be an image that is already in your registry to pull and set commands or env variables.
So I change the
web: build: . command: python manage.py runserver 0.0.0.0:8000 volumes: - .:/code ports: - "8000:8000" env_file: - ./env.dev depends_on: - db
and added a
web: command: /bin/bash run.sh image: registry.example.com:5000/my_image:0.1 ports: - "8000:8000" env_file: - ./env.dev depends_on: - db
So it is now pulling the image from the repo and running the command to set it up
