Shipyard（github）是建立在docker集群管理工具Citadel之上的可以管理容器、主机等资源的web图形化工具。包括core和extension两个版本，core即shipyard主要是把多个 Docker host上的 containers 统一管理（支持跨越多个host），extension即shipyard-extensions添加了应用路由和负载均衡、集中化日志、部署等
1.几个概念
engine
一个shipyard管理的docker集群可以包含一个或多个engine（引擎），一个engine就是监听tcp端口的docker daemon。shipyard管理docker daemon、images、containers完全基于Docker API，不需要做其他的修改。另外，shipyard可以对每个engine做资源限制，包括CPU和内存；因为TCP监听相比Unix socket方式会有一定的安全隐患，所以shipyard还支持通过SSL证书与docker后台进程安全通信。
rethinkdb
RethinkDB是一个shipyard项目的一个docker镜像，用来存放账号（account）、引擎（engine）、服务密钥（service key）、扩展元数据（extension metadata）等信息，但不会存储任何有关容器或镜像的内容。一般会启动一个shipyard/rethinkdb容器shipyard-rethinkdb-data来使用它的/data作为数据卷供另外rethinkdb一个挂载，专门用于数据存储。
2.启动Swarm Manager
docker run -tid \
-p 3375:3375 \
--restart=always \
--name shipyard-swarm-manager \
swarm:latest \
manage --host tcp://0.0.0.0:3375 consul://[consul server ip]:8500
3.启动Swarm Agent
docker run -tid \
--restart=always \
--name shipyard-swarm-agent \
swarm:latest \
join --addr [local ip]:2375 consul://[consul server ip]:8500
4.查看集群状态

5.启动Datastore(rethinkdb)
https://hub.tenxcloud.com/repos/docker_library/rethinkdb
https://hub.alauda.cn/repos/library/rethinkdb
提示:可以使用国内源index.tenxcloud.com/docker_library/rethinkdb
docker run -tid \
--restart=always \
--name shipyard-rethinkdb \
-p 28015:28015 \
-p 29015:29015 \
-v /data/rethinkdb:/data \
index.tenxcloud.com/docker_library/rethinkdb
6.部署shipyard镜像
docker run -tid \
--restart=always \
--name shipyard-controller \
--link shipyard-rethinkdb:rethinkdb \
--link shipyard-swarm-manager:swarm \
-p 80:8080 \
shipyard/shipyard:latest \
server \
-d tcp://swarm:3375
提示：
shipyard这里使用了--link和别名
rethinkdb默认监听28015,29015,8080，支持集群

这个就是web GUI控制台 http://localhost
可以实现容器，镜像，集群节点，registry,账号,事件的管理，非常简洁
注意:shipyard控制台默认的用户名和密码为admin/shipyard
