docker(4) swarm shipyard web集群管理工具
shipyard 同etcd进行服务发现，docker-machine 使用swarm自带管理，目前两者集群不能一起使用。1，设置下载源
#docker默认下载源，下了一整天都没下载下来，改成国内源 分分钟搞定
test@ubuntu:~$ curl -sSL https://get.daocloud.io/daotools/set_mirror.sh |sudosh -s http://abcd1234.m.daocloud.io
docker version >= 1.12
{"registry-mirrors": ["http://abcd1234.m.daocloud.io"]}
Success.
You need to restart docker to take effect: sudo systemctl restart docker.service
test@ubuntu:~$ sudo systemctl restart docker.service
2、安装shipyard
#现在软件安装方式越来越安逸了，一条命令就完成，最后还提示登陆或者发开放式
test@ubuntu:~$ curl -s https://shipyard-project.com/deploy | sudo bash -s

4 搭建 swarm集群
主控节点
test@swarm-master:~$ docker swarminit
Swarm initialized: current node (ly3wrhojt6ekl7gni6m5akdag) is now a manager.
To add a worker to this swarm, run the following command:
docker swarm join --token SWMTKN-1-5aqwhpkhcdunwdijo7v1vo320fllw6obnitpsj7ao9gtlirli5-42aqjvopqiftcggjsgk7m6122 192.168.1.80:2377
To add a manager to this swarm, run 'docker swarm join-token manager' and follow the instructions.
节点
test@swarm-node1:~$ docker swarm join --token SWMTKN-1-5aqwhpkhcdunwdijo7v1vo320fllw6obnitpsj7ao9gtlirli5-42aqjvopqiftcggjsgk7m6122 192.168.1.80:2377
This node joined a swarm as a worker.
5 测试
5.1 主控节点执行添加service
test@swarm-master:~$ docker service create --replicas 2 --name myhelloworld alpine ping docker.com
6vwul8y2c16a9kyt13zof2cvb
Since --detach=false was not specified, tasks will be created in the background.
In a future release, --detach=false will become the default.
#web界面查询一下2个新增容器
5.2 扩展容器
test@swarm-master:~$ docker service scale myhelloworld=10
myhelloworld scaled to 10
#web页面看一下，10个容器
