使用 Docker Toolbox 自动创建 Swarm 集群+Portainer 图形化管理的脚本
说明：
昨天，写了一篇《Docker Swarm 集群创建+Portainer 图形化管理实验》博客，地址为：http://blog.csdn.net/csdn_duomaomao/article/details/73381277 主要是通过手工实现的，解决 了Docker 初学者创建Swarm遇到的麻烦问题，但毕竟是手工的方式，今天父亲节，刚好在家有空，整了一篇自动创建的脚本，希望对大家学习Docker有帮助。
脚本：
# 初始设置M台管理节点,W台工作节点,其中manager1是leader节点.
M=3
W=2
# 创建M台Docker虚拟机,作为管理节点
for i in $(seq 1 $M)
do
docker-machine create \
--driver virtualbox \
--engine-registry-mirror=https://registry.docker-cn.com \
manager$i
done
#创建W台Docker虚拟机,作为工作节点
for j in $(seq 1 $W)
do
docker-machine create \
--driver virtualbox \
--engine-registry-mirror=https://registry.docker-cn.com \
worker$j
done
#切换 manager1 上,创建 Swarm 集群
eval $(docker-machine env manager1)
docker swarm init --advertise-addr $(docker-machine ip manager1):2377
# 获取两个令牌变量
# 切换到主控节点
eval $(docker-machine env manager1)
#显示管理节点加入集群的信息,截取其中的令牌作为变量,便于后面使用
T1=`docker swarm join-token manager|grep token`
TM=${T1:12:85}
#显示工作节点加入集群的信息,截取其中的令牌作为变量,便于后面使用
T2=`docker swarm join-token worker|grep token`
TW=${T2:12:85}
# 两个令牌TM、TW变量获取完毕
# 通过循环命令,把其他的控制节点都加入到集群中
for i in $(seq 2 $M)
do
eval $(docker-machine env manager$i)
docker swarm join \
--token $TM \
$(docker-machine ip manager1):2377
done
# 通过循环命令,把其他的工作节点都加入到集群中
for i in $(seq 1 $W)
do
eval $(docker-machine env worker$i)
docker swarm join \
--token $TW \
$(docker-machine ip manager1):2377
done
# 在主控节点上部署 Portainer 服务,图形化的 Docker 管理平台
eval $(docker-machine env manager1)
docker service create \
--name portainer \
--publish 9000:9000 \
--constraint 'node.role == manager' \
--mount type=bind,src=//var/run/docker.sock,dst=/var/run/docker.sock \
portainer/portainer \
-H unix:///var/run/docker.sock
# 在主控节点上部署 visualizer 服务,图形化的方式查看集群运行情况
eval $(docker-machine env manager1)
docker service create \
--name=viz \
--publish=8088:8080/tcp \
--constraint=node.role==manager \
--mount=type=bind,src=/var/run/docker.sock,dst=/var/run/docker.sock \
manomarks/visualizer
# 尝试在机器中部署一个测试服务 httpd ,检查集群是否能正常使用.
# 因为要从网络上下载httpd 镜像,可能要等1-几分钟,有加速器会很快,5分钟
eval $(docker-machine env manager1)
docker service create --name httpd --publish 80:80 --replicas=6 httpd
echo 访问 Portainer 的方法: http://$(docker-machine ip manager1):9000
echo 访问 Visualizer 的方法: http://$(docker-machine ip manager1):8088
echo 访问 测试网站 的方法: http://$(docker-machine ip manager1) 或者集群中的任何节点的IP地址

Swarm initialized: current node (pc80navfg4xpz231611tlerqo) is now a manager.
To add a worker to this swarm, run the following command:
docker swarm join \
--token SWMTKN-1-4y3b6md725lsk4udkme70rrj64q1hn9uc9249lwzct2ltvq22w-bmreaixp

To add a manager to this swarm, run 'docker swarm join-token manager' and follow
the instructions.
