Shipyard 是一个管理容器、主机等资源的web图形化工具，它建立在docker集群管理工具Citadel之上。有core和extension两个版本：

engine

一个shipyard管理的docker集群可以包含一个或多个engine，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。

搭建

修改配置文件

vim /etc/sysconfig/docker

#修改other_args值
other_args="-H tcp://0.0.0.0:4243 -H unix:///var/run/docker.sock"

#重启docker后查看端口
netstat -plt | grep 4243

启动rethinkdb

docker pull shipyard/shipyard


docker run -it -d --name shipyard-rethinkdb-data \
--entrypoint /bin/bash shipyard/rethinkdb -l

docker run -it -P -d --name shipyard-rethinkdb \
--volumes-from shipyard-rethinkdb-data shipyard/rethinkdb

docker run -it -p 8080:8080 -d --name shipyard \
--link shipyard-rethinkdb:rethinkdb shipyard/shipyard

shipyard-cli

图形界面没有提供修改密码的功能，不过可以通过shipyard-cli来修改。

docker run -ti --rm shipyard/shipyard-cli

docker run -it shipyard/shipyard-cli

#执行shipyard-cli后，通过下面的命令查看更多功能
shipyard cli> shipyard help
