Centos下安裝Docker集羣管理工具Shipyard

 

1、 Docker Shipyard是什麼 ？

shipyard是一個開源的docker管理平臺，其特性主要包括：

1 支持鏡像管理、容器管理。 2 支持控制檯命令 3 容器資源消耗監控 4 支持集羣swarm，能夠隨意增長節點 5 支持控制用戶管理權限，能夠設置某個容器對某個用戶只讀、管理權限。 6 有漢化版

缺點：

1 不支持image管理； 2 不支持container批量操做。 3 啓動容器較多，佔用每一個節點的一部分資源

 Shipyard的幾個概念

1）engine 一個shipyard管理的docker集羣能夠包含一個或多個engine（引擎），一個engine就是監聽tcp端口的docker daemon。 shipyard管理docker daemon、images、containers徹底基於Docker API，不須要作其餘的修改。 另外，shipyard能夠對每一個engine作資源限制，包括CPU和內存；由於TCP監聽相比Unix socket方式會有必定的安全隱患， 因此shipyard還支持經過SSL證書與docker後臺進程安全通訊。 2）rethinkdb RethinkDB是一個shipyard項目的一個docker鏡像，用來存放帳號（account）、引擎（engine）、服務密鑰（service key）、 擴展元數據（extension metadata）等信息，但不會存儲任何有關容器或鏡像的內容。

Shipyard生態

shipyard是由shipyard控制器以及周圍生態系統構成，如下按照deploy啓動順序進行介紹（下面幾個就是shipyard使用腳本安裝後，啓動的幾個容器名） 1）RethinkDB deploy首先啓動的就是RethinkDB容器，shipyard採用RethinkDB做爲數據庫來保存用戶等信息 2）Discovery 爲了使用Swarm，咱們須要一個外部的密鑰值存儲羣容器，shipyard默認是採用了etcd。 3）shipyard_certs 證書管理容器，實現證書驗證功能 4）Proxy 默認狀況下，Docker引擎只監聽Socket，咱們能夠從新配置引擎使用TLS或者使用一個代理容器，轉發請求從TCP到Docker監聽的UNIX Socket。 5）Swarm Manager Swarm管理器 6）Swarm Agent Swarm代理，運行在每一個節點上。 7）Controller shipyard控制器，Remote API的實現和web的實現。

 

 

2、安裝前準備

系統：Centos7
時間同步
可鏈接外網，添加yum源
關閉selinux

 

三安裝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、安裝Shipyard master端

1.下載鏡像，下載前需先配置加速器，不然下載速度感人......

使用加速器下載官網鏡像方法：

1.打開https://dev.aliyun.com/ 連接，按提示申請一個帳戶

2.點擊容器鏡像服務，再點擊容器加速器按提示設置便可

 

 

加速器配置好後開始下載鏡像

[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.修改安裝腳本,修改成下載中文鏡像

a.修改成下載中文鏡像 [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 #確保8080端口沒有被使用,不然要修改腳本 [root@localhost ~]#netstat -tlnp | grep 8080 #修改腳本 [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.啓動  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

根據提示信息 訪問   http://192.168.0.104:8080 ，用戶名和密碼爲admin：shipyard

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

 

4.訪問Shipyard

輸入帳號密碼登陸

 

 5.添加node節點(node節點須要安裝docker並啓動)

[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爲192.168.0.106，咱們在shipyard上查看一下

點擊節點管理，192.168.0.106已結添加完成
