如何使用分子而不是使用“組合”獨立運行 docker 圖像？

Question

我有這個 docker-compose.yaml。 它定義了 1 個公共服務 API 和 4 個服務（復制），每個服務有另外兩個微服務（一個接收事件，另一個將信息保存到 mongo）。 當我執行“docker-compose up”時，這非常有效。 但我想用“docker run”運行每個圖像。

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

    internal: false

當我執行“撰寫運行監視器日志公共”時，執行會因任何原因而關閉。

我可以看到這個執行不知道需要加載“api”服務，但是在 docker-compose.yaml 中定義的，為什么圖像沒有讀取？

Answer 1

只需在docker run中設置環境變量

例如

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

Answer 2

只需使用 docker-compose 的選項：

docker-compose up <your_service_name>

例如：

docker-compose up monitor-1
