Centos下安装Docker集群管理工具Shipyard

 

1、 Docker Shipyard是什么 ？

shipyard是一个开源的docker管理平台，其特性主要包括：

1 支持镜像管理、容器管理。 2 支持控制台命令 3 容器资源消耗监控 4 支持集群swarm，能够随意增长节点 5 支持控制用户管理权限，能够设置某个容器对某个用户只读、管理权限。 6 有汉化版

缺点：

1 不支持image管理； 2 不支持container批量操做。 3 启动容器较多，占用每一个节点的一部分资源

 Shipyard的几个概念

1）engine 一个shipyard管理的docker集群能够包含一个或多个engine（引擎），一个engine就是监听tcp端口的docker daemon。 shipyard管理docker daemon、images、containers彻底基于Docker API，不须要作其余的修改。 另外，shipyard能够对每一个engine作资源限制，包括CPU和内存；由于TCP监听相比Unix socket方式会有必定的安全隐患， 因此shipyard还支持经过SSL证书与docker后台进程安全通讯。 2）rethinkdb RethinkDB是一个shipyard项目的一个docker镜像，用来存放帐号（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。

Shipyard生态

shipyard是由shipyard控制器以及周围生态系统构成，如下按照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做为数据库来保存用户等信息 2）Discovery 为了使用Swarm，咱们须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 默认状况下，Docker引擎只监听Socket，咱们能够从新配置引擎使用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，运行在每一个节点上。 7）Controller shipyard控制器，Remote API的实现和web的实现。

 

 

2、安装前准备

系统：Centos7
时间同步
可链接外网，添加yum源
关闭selinux

 

三安装docker

[root@localhost ~]# yum install docker -y [root@localhost ~]# docker start docker [root@localhost ~]# systemctl enable docker Created symlink from /etc/systemd/system/multi-user.target.wants/docker.service to /usr/lib/systemd/system/docker.service.

 

4、安装Shipyard master端

1.下载镜像，下载前需先配置加速器，不然下载速度感人......

使用加速器下载官网镜像方法：

1.打开https://dev.aliyun.com/ 连接，按提示申请一个帐户

2.点击容器镜像服务，再点击容器加速器按提示设置便可

 

 

加速器配置好后开始下载镜像

[root@localhost ~]#docker pull rethinkdb [root@localhost ~]#docker pull microbox/etcd [root@localhost ~]#docker pull shipyard/docker-proxy [root@localhost ~]#docker pull swarm [root@localhost ~]#docker pull dockerclub/shipyard

 

2.修改安装脚本,修改成下载中文镜像

a.修改成下载中文镜像 [root@localhost ~]#wget https://shipyard-project.com/deploy
[root@localhost ~]#grep -n shipyard:latest deploy [root@localhost ~]#sed -i 's/shipyard\/shipyard:latest/dockerclub\/shipyard:latest/g' deploy b.修改端口 #确保8080端口没有被使用,不然要修改脚本 [root@localhost ~]#netstat -tlnp | grep 8080 #修改脚本 [root@localhost ~]#grep -n 'PORT:-8080' deploy SHIPYARD_PORT=${PORT:-8080} #修改成 SHIPYARD_PORT=${PORT:-指定端口} [root@localhost ~]#sed 's/PORT:-8080/PORT:-8090/g' deploy | grep "PORT:-8090"

 

3.启动  sh deploy

[root@localhost ~]# sh deploy Unable to find image 'alpine:latest' locally Trying to pull repository docker.io/library/alpine ... latest: Pulling from docker.io/library/alpine 2fdfe1cd78c2: Pulling fs layer 2fdfe1cd78c2: Verifying Checksum 2fdfe1cd78c2: Download complete 2fdfe1cd78c2: Pull complete Digest: sha256:ccba511b1d6b5f1d83825a94f9d5b05528db456d9cf14a1ea1db892c939cda64 Deploying Shipyard -> Starting Database -> Starting Discovery -> Starting Cert Volume -> Starting Proxy -> Starting Swarm Manager -> Starting Swarm Agent -> Starting Controller Waiting for Shipyard on 192.168.0.104:8080 Shipyard available at http://192.168.0.104:8080
Username: admin Password: shipyard

根据提示信息 访问   http://192.168.0.104:8080 ，用户名和密码为admin：shipyard

 注：删除命令  cat deploy | ACTION=remove bash  

 

4.访问Shipyard

输入帐号密码登陆

 

 5.添加node节点(node节点须要安装docker并启动)

[root@localhost ~]# curl https://shipyard-project.com/deploy | ACTION=node DISCOVERY=etcd://192.168.0.104:4001 bash

提示node添加成功，IP为192.168.0.106，咱们在shipyard上查看一下

点击节点管理，192.168.0.106已结添加完成
