Docker-Compose使用例子

　　本实例，使用Docker-Compose根据已有tomcat镜像，批量创建5个容器

• 下载 docker-compose

curl -L https://get.daocloud.io/docker/compose/releases/download/1.24.0/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose

• 修改权限

chmod +x /usr/local/bin/docker-compose

• 验证是否安装成功

docker-compose --version

• 创建工作目录

mkdir -p  /opt/docker-ch3-boot-cluster

• 编辑yml文件

 vi docker-compose.yml

• 添加脚本

version: '3'
services:
  ch3-boot-9080:
    restart: always
    image: tomcat
    container_name: ch3-boot-9080
    ports:
      - "9080:8080"
  ch3-boot-9081:
    restart: always
    image: tomcat
    container_name: ch3-boot-9081
    ports:
      - "9081:8080"
  ch3-boot-9082:
    restart: always
    image: tomcat
    container_name: ch3-boot-9082
    ports:
      - "9082:8080"
  ch3-boot-9083:
    restart: always
    image: tomcat
    container_name: ch3-boot-9083
    ports:
      - "9083:8080"
  ch3-boot-9084:
    restart: always
    image: tomcat
    container_name: ch3-boot-9084
    ports:
      - "9084:8080"

• 执行后台运行命令

 docker-compose up -d
