I'm new to docker and I'm using a compose file to build from a Dockerfile and run and image for me I have the following yml file
version: '2' services: multichain: build: ./ image: ubuntu:15.04 read_only: false volumes: - .:/data:rw working_dir: /data #entrypoint: node server/index.js
docker-compose up --build produces
REPOSITORY TAG IMAGE ID CREATED SIZE <none> <none> 5c5580fb6ce4 2 minutes ago 175.1 MB ubuntu 15.04 d1b55fd07600 10 months ago 131.3 MB
Which is expected but can I replace the "" with something during the build in docker-compose?
Also when I run the file again it will create another : can't I just replace whats already there?
