how to build docker image by docker-compose.yml

Question

Here is my docker-compose.yml:

version: '2'
services:
web:
  build: .
  context: ./
  dockerfile: Dockerfile
  ports:
    - "8080:8080"
  container_name: demo
  volumes:
    - .:/images

I got an error:

ERROR: The Compose file './docker-compose.yml' is invalid because: Unsupported config option for services.web: 'dockerfile'

So I would like to build the container and also run. I will have a few more containers to build and run. Is it possible by docker-compose?

Answer 1

If I'm not mistaken the issue is after build you have a dot, the dockerfile and context are not correct idented. And I think the bar in the context should not be there.

version: "3.7"
services:
  api:
    image: image-name
    build:
      context: .
      dockerfile: path/to/Dockerfile
    container_name: container-name

I think this resolves the issue you have, but couldn't test it.
