Shipyard doker环境搭建（二）

下面先把已经搭建好的doker可视化页面给大家截图，如下图所示还支持集群的操作，不过关于集群方面的知识等后面学到的再去写博客给大家进行更细致的讲解

在搭建之前，同样是为了速度，docker需要镜像源，具体可参考
https://blog.csdn.net/baidu_19473529/article/details/78126869
下面是具体的搭建步骤

[root@docker-218 ~]# cat /etc/redhat-release
CentOS Linux release 7.5.1804 (Core)
[root@docker-218 ~]# ifconfig|grep 172.16.60.218
inet 172.16.60.218 netmask 255.255.255.0 broadcast 172.16.60.255
关闭主机防火墙
[root@docker-218 ~]# systemctl disable firewalld.service
[root@docker-218 ~]# systemctl stop firewalld.service
[root@docker-218 ~]# iptables -F
[root@docker-218 ~]# firewall-cmd --state
not running
启动docker服务
[root@docker-218 ~]# systemctl start docker
#下载相关镜像(这些镜像如果不提前下载,则在下面一键安装部署时会自动下载,不过要等待一段时间. 所以最好提前下载,一键部署时就很快了)
[root@docker-218 ~]# docker pull rethinkdb
[root@docker-218 ~]# docker pull microbox/etcd
[root@docker-218 ~]# docker pull shipyard/docker-proxy
[root@docker-218 ~]# docker pull swarm
[root@docker-218 ~]# docker pull dockerclub/shipyard
#下载官方一键部署脚本
#最新下载地址: https://pan.baidu.com/s/1ATM32S7tLA35Q-xK7-TgzQ    
#提取密码: kgqi
 #接着执行一键部署
#替换Controller为中文版
[root@docker-213 ~]# chmod 755 shipyard-deploy
[root@docker-213 ~]# sh shipyard-deploy

Waiting for Shipyard on 172.16.60.213:8080
Shipyard available at http://172.16.60.213:8080
Username: admin Password: shipyard
部署后,可以看到相应的shipyard容器已经创建好了
[root@docker-218 ~]# docker ps
CONTAINER ID        IMAGE                          COMMAND                  CREATED             STATUS              PORTS                                            NAMES

最后访问http://172.16.60.218:8080,使用admin/shipyard用户名和密码登录即可.  (注意:一键部署之后,需要稍等一会儿,8080端口才能起来)
===================================================================================
如果想要修改web访问端口,则操作如下:
[root@docker-218 ~]# 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
[root@docker-218 ~]# sed -i 's/8080/80/g' shipyard-deploy 
然后重新部署即可
在这里着重强调一下，如果正在运行的容器需要先停止，然后再执行 rm 操作，最终执行sh shipyard-deploy 即可
下面列出批量stop和rm的指令，这样操作比较方便一些
docker stop  $(docker ps -a -q) //停止
docker rm  $(docker ps -a -q) //删除

删除Shipyard环境操作

[root@docker-218 ~]# cat shipyard-deploy |ACTION=remove bash            
Removing Shipyard

Shipyard添加其他节点主机(centos7.X系统的主机)的操作记录

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)
[root@docker-220 ~]# cat shipyard-deploy| ACTION=node DISCOVERY=etcd://172.16.60.218:4001 bash
......
Node added to Swarm: 172.16.60.220
 
[root@docker-220 ~]# docker ps

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://172.16.60.218:8080,在"容器管理"-"主机节点"中看到添加的节点信息了.
 
删除节点机
[root@docker-220 ~]# cat shipyard-deploy |ACTION=remove bash -s
Removing Shipyard
 -> Removing Database
 -> Removing Discovery
 -> Removing Cert Volume
 -> Removing Proxy
 -> Removing Swarm Agent
 -> Removing Swarm Manager

Nginx做域名转发: 在nginx配置文件http块里添加如下代码:

upstream shipyard {
     server 172.16.60.218:8080;
}
server {
    listen          80;
    server_name     kevin.shipyard.com;
  
    location / {
        proxy_pass http://shipyard;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
    }
}
 
 
以下三行代码为nginx做WebSockets跳转否则，在执行shell时会报400错误
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
