112、如何使用stack （Swarm19）

参考https://www.cnblogs.com/CloudMan6/p/8135714.html

定义好了 stack YAML 文件，就可以通过 docker stack deploy 命令部署应用，命令最后面的wpstack 是自动创建各项资源的前缀，方便区分不同的环境

root@host03:~# docker stack deploy -c wp.yaml wpstack # 部署stack

Creating network wpstack_default

Creating secret wpstack_db_password

Creating secret wpstack_db_root_password

Creating service wpstack_db

Creating service wpstack_wordpress

root@host03:~# docker stack ls # 查看stack list

NAME SERVICES ORCHESTRATOR

wpstack 2 Swarm

root@host03:~# docker stack services wpstack # 查看某stack包含的service list

ID NAME MODE REPLICAS IMAGE PORTS

60gocweop7sy wpstack_wordpress replicated 1/1 wordpress:latest *:80->80/tcp

wpi8ieo8k89z wpstack_db replicated 0/1 mysql:5.7

root@host03:~# docker service ps wpstack_db # 查看 **_db service

ID NAME IMAGE NODE DESIRED STATE CURRENT STATE ERROR PORTS

root@host03:~# sed -i 's/80:80/81:80/' wp.yaml # 修改wordpress对外端口号

root@host03:~# docker stack deploy -c wp.yaml wpstack # 更新stack 配置

Updating service wpstack_db (id: wpi8ieo8k89z46ahxuwbnu357)

Updating service wpstack_wordpress (id: 60gocweop7sytwa5eab7zffkf)

访问 http://10.12.31.211 验证部署结果

root@host03:~# docker stack rm wpstack # 删除stack

Removing service wpstack_db

Removing service wpstack_wordpress

Removing secret wpstack_db_password

Removing secret wpstack_db_root_password

Removing network wpstack_default

如果想更新stack的某些属性，直接修改 YAML文件即可，然后再次执行上面的命令。
