Docker-compose实战案例

 

• 查看系统镜像，将lesson01镜像，使用Docker-compose管理，创建6个容器

docker images

• 创建/opt/lesson01-cluster集群目录，并在里面创建docker-compose.yml集群文件

 

version: '3.1'
services:
  lesson01-8080:
    restart: always
    image: lesson01
    container_name: lesson01-8080
    ports:
     - 8080:8080
  lesson01-8081:
    restart: always
    image: lesson01
    container_name: lesson01-8081
    ports:
     - 8081:8080    
  lesson01-8082:
    restart: always
    image: lesson01
    container_name: lesson01-8082
    ports:
     - 8082:8080     
  lesson01-8083:
    restart: always
    image: lesson01
    container_name: lesson01-8083
    ports:
     - 8083:8080     
  lesson01-8084:
    restart: always
    image: lesson01
    container_name: lesson01-8084
    ports:
     - 8084:8080
  lesson01-8085:
    restart: always
    image: lesson01
    container_name: lesson01-8085
    ports:
     - 8085:8080

　注意：以下几个命令，需要在docker-compose.yml同级目录中执行，否则无法启动，配置的端口，无需单独开放端口映射，docker-proxy会帮我们创建，容器销毁后，端口关闭

• 启动容器,-d以守护进程方式

 docker-compose  up -d

• 停止容器

docker-compose stop

• 启动容器

 docker-compose start

• 删除容器

 docker-compose down

• 部署后，成功访问
