Docker（3） —— docker-compose

1、安装docker-compose

yum -y install epel-release
yum -y install python-pip
pip install docker-compose
#待安装完成后，执行查询版本的命令
docker-compose version

docker-compose编排容器时会读取yaml文件的配置，以下是一个以hello-service工程为例的配置文件，并使用了eureka和feign：

version: "3"

services:
  eureka-server1:
    image: cmpaas/eureka-server:1.0.0
    networks:
      - cmpaas_net
    ports:
      - "8361:8361"
    environment:
      - spring.profiles.active=peer1
  eureka-server2:
    image: cmpaas/eureka-server:1.0.0
    networks:
      - cmpaas_net
    ports:
      - "8362:8362"
    environment:
      - spring.profiles.active=peer2
  hello-feign-service:
    image: cmpaas/hello-feign-service:1.0.0
    networks:
      - cmpaas_net
    ports:
      - "9881:8080"
    depends_on:
      - eureka-server1
      - eureka-server2
      - hello-service
    links:
      - eureka-server1
      - eureka-server2
      - hello-service
  hello-service:
    image: cmpaas/hello-service:1.0.0
    networks:
      - cmpaas_net
    ports:
      - "8083:8080"
    depends_on:
      - eureka-server1
      - eureka-server2
    links:
      - eureka-server1
      - eureka-server2
      
networks:
  cmpaas_net:

如果该配置文件的文件名是docker-compose.yml，可以到yaml文件所在目录下使用以下命令执行：

docker-compose up -d

否则需要指定yaml的文件名：

docker-compose -f spring-cloud-compose.yml up -d
