how to build docker image by docker-compose.yml

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?

YAML files works on indentation and an indentation error marks the yaml as invalid. Always validate your yaml in appropriate linting tool for e.g. https://www.yamllint.com/

version: '3.7'
services:
  web:
    image: my-web-service
    build:
      dockerfile: Dockerfile
      context: .
    ports:
      - '9080:8080'

context value is . because my Dockerfile and docker-compose.yaml files exists at the same location

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.

You need to respect the indentations , here is an example for building Nginx docker image https://github.com/wshihadeh/three_methods_to_share_assets/blob/master/precompile_during_docker_build/docker-compose.yml 

version: '3.7'
services:
  web:
    build:
      context: nginx
      dockerfile: Dockerfile
    command: server
    ports:
      - 80:80
