Docker 容器编排的应用

案例一

提前安装好docker-compose
使用 mysql:5.6 镜像和 WordPress:latest镜像,在/root/wordpress目录下创建docker-compose.yaml文件，编排部署WordPress，并设置restart策略

[[e-mail] ~]# mkdir wordpress
[[e-mail] ~]# cd wordpress/
[[e-mail] wordpress]# vi docker-compose.yaml
注意每一行的缩进
mysql:
  image: mysql:5.6  
  restart: always
  ports:
    - "3306:3306"
  environment:
    MYSQL_ROOT_PASSWORD: 123456
    MYSQL_DATABASE: wordpress
    MYSQL_USER: wordpress
    MYSQL_PASSWORD: 123456

wordpress:
  image: wordpress:latest
  restart: always
  ports:
    - "80:80"
  links:
    - "mysql:mysql"
  environment:
    WORDPRESS_DB_NAME: wordpress
    WORDPRESS_DB_USER: wordpress
    WORDPRESS_DB_PASSWORD: 123456

启动测试
[[e-mail] wordpress]# docker-compose up -d 
Creating wordpress_mysql_1 ... done
Creating wordpress_wordpress_1 ... done

查看启动是否成功
[[e-mail] wordpress]# docker ps 
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                    NAMES

使用 mysql:5.6 镜像和 owncloud :latest镜像,在/root/owncloud目录下创建docker-compose.yaml文件，编排部署owncloud，并设置restart策略

[[e-mail] ~]# mkdir owncloud
[[e-mail] ~]# cd owncloud/
[[e-mail] owncloud]# vi docker-compose.yaml
mysql:
  image: mysql:5.6 
  restart: always

    - "mysql:mysql"
  environment:
    WONCLOUD_DB_NAME: owncloud
    WONCLOUD_DB_USER: owncloud
    WONCLOUD_DB_PASSWORD: 123456

启动测试
[[e-mail] owncloud]# docker-compose up -d 
Creating owncloud_mysql_1 ... done
Creating owncloud_owncloud_1 ... done

查看启动状态
[[e-mail] owncloud]# docker ps
