Shipyard是在Docker Swarm实现对容器、镜像、docker集群、仓库、节点进行管理的web系统。
1.Shipyard功能
1
|
Shipyard是一个集成管理docker容器、镜像、Registries的系统,它可以简化对横跨多个主机的Docker容器集群进行管理. 通过Web用户界面,你可以大致浏览相关信息,比如你的容器在使用多少处理器和内存资源、在运行哪些容器,还可以检查所有集群上的事件日志。 |
2.Shipyard特点:

|
支持多节点的集成管理; 支持镜像、容器、节点管理等功能; 可视化的容器管理和监控管理; 可动态加载节点。 |
3.Shipyard几个概念
1)engine
1
|
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dockerdaemon。shipyard管理docker daemon、images、containers完全基于<br>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<br>SSL证书与docker后台进程安全通信。 |
2)rethinkdb
1
|
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<br>任何有关容器或镜像的内容。 |
4.Shipyard生态
shipyard是由shipyard控制器以及周围生态系统构成,以下按照deploy启动顺序进行介绍(下面几个就是shipyard使用脚本安装后,启动的几个容器名)

1)RethinkDB deploy首先启动的就是RethinkDB容器,shipyard采用RethinkDB作为数据库来保存用户等信息 2)Discovery 为了使用Swarm,我们需要一个外部的密钥值存储群容器,shipyard默认是采用了etcd。 3)shipyard_certs 证书管理容器,实现证书验证功能 4)Proxy 默认情况下,Docker引擎只监听Socket,我们可以重新配置引擎使用TLS或者使用一个代理容器,转发请求从TCP到Docker监听的UNIX Socket。 5)Swarm Manager Swarm管理器 6)Swarm Agent Swarm代理,运行在每个节点上。 7)Controller shipyard控制器,Remote API的实现和web的实现。 |

[root@pre1 gh] # cat /etc/redhat-release CentOS Linux release 7.2.1511 (Core) [root@pre1 gh] # ifconfig|grep 192.168.3.141 inet 192.168.3.141 netmask 255.255.255.0 broadcast 192.168.3.255 |
6.安装最新版docker
1
|
[root@pre1 ~] # curl -fsSL https://get.docker.com/ | sh |
修改docker配置文件,添加下面一行,进行docker加速设置
1
2
|
[root@pre1 ~] # vim /etc/sysconfig/docker //在文件底部添加下面一行, (这里就是直接写: xxx.mirror.aliyuncs.com) ADD_REGISTRY= '--add-registry xxx.mirror.aliyuncs.com' |
启动docker服务
1
|
[root@docker-218 ~] # systemctl start docker |
加入开机自启动
1
|
[root@pre1 ~] # systemctl enable docker |
7.下载相关镜像

最后访问http://192.168.3.141:8080,使用admin/shipyard用户名和密码登录即可
如果想要修改web访问端口,则操作如下:
1

3
|
[root@pre1 ~] # cat shipyard-deploy |grep 8080 echo " PORT: specify the listen port for the controller (default: 8080)" SHIPYARD_PORT=${PORT:-8080} |
比如将脚本中默认的8080端口改为80端口
1
|
[root@pre1 ~] # sed -i 's/8080/80/g' shipyard-deploy |
然后重新部署即可
附:登录页面
进入之后的管理页面

11.Shipyard添加其他节点主机
比如将172.16.60.220机器节点加入到上面的shipyard管理中.
则需要在被加入节点机器上如下操作:
1) 在被加入的节点上按照上面的最新地址下载shipyard-deploy
2) 执行下面操作 (注意下面etcd地址要写成shipyard部署机的ip地址. 首次执行时会自动下载镜像,需要等待一段时间)

注意,添加节点时,上面一键脚本需要运行在被添加的节点主机上,而不是shipyard部署节点的机器上.
然后登录http://192.168.3.141:8080,在"容器管理"-"主机节点"中看到添加的节点信息了.
