自我提示示例：

services: 
  web1: 
    container_name: web1
    image: "centos:jdk"
    healthcheck:
      test: ["CMD", "curl","-s","-f", "http://localhost:80"]
      interval: 5s
      timeout: 5s
      retries: 3
    ports: 
      - "8080:80"
    privileged: true
    volumes: 
      - "/home/shenyi/nginx/web1/:/var/www/html/"
    networks:
      mynginx-net:
        ipv4_address: ${web1_addr}

  web2: 
    container_name: web2
    image: "centos:jdk"
    ports: 
      - "8081:80"
    privileged: true
    volumes: 
      - "/home/shenyi/nginx/web2/:/var/www/html/"
    networks:
      mynginx-net:
        ipv4_address: 192.156.0.3
    healthcheck:
      test: ["CMD", "curl","-s","-f", "http://localhost:80"]
      interval: 5s
      timeout: 5s
      retries: 3


  nginx:
    container_name: mynginx
    image: "centos:nginx"
    healthcheck:
      test: ["CMD", "curl","-s","-f", "http://localhost:80"]

      - "9090:80"
    privileged: true
    volumes:
      - "/home/shenyi/nginx/conf/nginx.conf:/etc/nginx/nginx.conf"
    networks:
      mynginx-net:
        ipv4_address: 192.156.0.2
networks:
  mynginx-net:
    driver: bridge
    ipam:
