如何使用分子而不是使用“组合”独立运行 docker 图像？

Question

I have got this docker-compose.yaml. It defines 1 service with the public API and 4 services (replicated) with another two microservices each one (one receives events and another one saves info to mongo). This works perfectly when i do "docker-compose up". But I want to run each images with "docker run".

version: "3.3"

services:

  api:
    build:
      context: .
    image: monitor-log-public
    #container_name: monitor-log-public
    env_file: docker-compose.env
    environment:
      SERVICES: api
      PORT: 3000
    #depends_on:
    #  - redis
    labels:
      - "traefik.enable=false"
      - "traefik.http.routers.api-gw.rule=PathPrefix(`/`)"
      - "traefik.http.services.api-gw.loadbalancer.server.port=3000"
    networks:
      - internal
    ports: 
      - 3000:3000

  monitor-1:
    build:
      context: .
    image: monitor-log-monitor-1
    #container_name: monitor-log-logger
    env_file: docker-compose.env
    environment:
      SERVICES: monitor,logs.db
    #depends_on:
    #  - redis
    networks:
      - internal   
      
  monitor-2:
    build:
      context: .
    image: monitor-log-monitor-2
    #container_name: monitor-log-logger
    env_file: docker-compose.env
    environment:
      SERVICES: monitor,logs.db
    #depends_on:
    #  - redis
    networks:
      - internal   

  monitor-3:
    build:
      context: .
    image: monitor-log-monitor-3
    #container_name: monitor-log-logger
    env_file: docker-compose.env
    environment:
      SERVICES: monitor,logs.db
    #depends_on:
    #  - redis
    networks:
      - internal   

  monitor-4:
    build:
      context: .
    image: monitor-log-monitor-4
    #container_name: monitor-log-logger
    env_file: docker-compose.env
    environment:
      SERVICES: monitor,logs.db
    #depends_on:
    #  - redis
    networks:
      - internal   

  #redis:
  #  image: redis:alpine
  #  networks:
  #    - internal

networks:
  internal:
    internal: false

volumes:

When I do "compose run monitor-log-public", the execution closes with any reason.

c:\temp\monitor-log-image>docker run monitor-log-monitor-1

I can see that this execution does not know that needs to load "api" service, but that is defined in the docker-compose.yaml, why the image does not read that??

Answer 1

Just set the env vars in docker run , as well

Eg

docker run -e SERVICES="monitor,logs.db" monitor-log-monitor-1

Answer 2

Just use docker-compose's options:

docker-compose up <your_service_name>

For example:

docker-compose up monitor-1
