docker利用WebHook实现持续集成
服務器
研發小伙伴可能對下列操作步驟會深有體會
寫代碼--》提交代碼--》打包--》發布
在項目調試測試階段,可能經常需要重復上面的步驟,以便將最新代碼部署到特定環境供測試人員或其他人員使用
CI即持續集成的提出及各種解決方案,減輕了很多最初簡單但繁瑣的工作
本文將通過提交代碼到git,然后通過webHook觸發jenkins打包并發布到相應容器中,開發人員只需提交代碼,后續打包發布都自動實現
git :我使用的碼云 我的主頁為: https://gitee.com/xiaochangwei
jenkins:Jenkins ver. 2.89.2
tomcat 8 jdk8 maven3.5
[root@iZnz7e74o4ag3oZ webapps]# java -version java version 1.8.0_121 Java(TM) SE Runtime Environment (build 1.8.0_121-b13) Java HotSpot(TM) 64-Bit Server VM (build 25.121-b13, mixed mode) [root@iZnz7e74o4ag3oZ webapps]# mvn -version Apache Maven 3.5.0 (ff8f5e7444045639af65f6095c62210b5713f426; 2017-04-04T03:39:06+08:00) Maven home: /usr/local/src/maven Java version: 1.8.0_121, vendor: Oracle Corporation Java home: /usr/local/src/jdk/jre Default locale: en_US, platform encoding: UTF-8 OS name: linux, version: 3.10.0-693.2.2.el7.x86_64, arch: amd64, family: unix [root@iZnz7e74o4ag3oZ webapps]#
配置好環境后,在tomcat中運行jenkins,并設置好用戶名密碼確保能正常登錄使用
操作步驟:
1.安裝插件 Generic Webhook Trigger Plugin、Deploy to container Plugin、Git plugin 由于這里暫時未發布到docker中,通過Deploy to container Plugin發布到tomcat中的
2.上傳maven項目到https://gitee.com
3.jenkins中新建項目ci
3.1 配置提交的代碼地址,Add有權限的用戶名和密碼(我的是私有項目),指定分支
3.2:配置maven命令以及發布到的tomcat
注意:發布項目的tomcat需要設置用戶信息,即修改conf下的user.xml 具體可以參考我很早之前寫的 http://www.cnblogs.com/xiaochangwei/p/4952644.html
這樣就可以手動構建項目了,請確保手動構建能成功后再進行下列操作
遇見的問題及解決方案:
如果構建時提示權限不對
生成公鑰: ssh-keygen -t rsa 一直回車直結束
cat ~/.ssh/id_rsa.pub 將內容增加到碼云上
如果還提示沒權限
手動先在jenkins運行的機器上clone一次代碼 如 git clone git@gitee.com:xiaochangwei/ci-demo.git 注意輸入yes
然后再看.ssh目錄,多了一個known_hosts 里面有碼云了,然后再手動構建,應該就能成功了
至此,手動打包并部署就已經實現了
------------------------------自動部署 --------------------------------------------------
1. 安裝上述插件后勾選Generic Webhook Trigger 增加post參數 ref expression值為 $.ref 注意有個點
增加optional filter
其實上面這部分不用設置也行,尤其是只會在jenkins中部署一個項目的一個分支時,只需要勾選上Generic Webhook Trigger就可以的
2. 在碼云中增加hook:http://USER ID:API TOKEN@jenkins部署的地址:端口號/jenkins/generic-webhook-trigger/invoke (紅色這部分不要變)
(這里不用api token 直接用jenkins的登錄密碼也可以, api token查看地址為:jenkins-用戶-點擊用戶名-api token)
同時勾選push或者其他你認為需要觸發部署的事件
提交后點擊測試,如果返回ok,則表示成功,切換到jenkins,查看項目是否能夠自動部署
我自己寫了一個接口用來獲取點擊測試后,到底請求了些什么
格式化下內容如下:

其實多建立幾個項目然后獲取信息后會發現,不同項目間存在差異的就是project.git_ssh_url 和分支 ref
至此,單個項目的自動部署就完了
如果你在jenkins中有多個項目,你觸發其中的一個webHook你就會發現,所有的項目都在構建?
這就有點不科學了,本來只想構建A項目,結果Abc項目都構建了? 要解決這個就需要用到上面提到的post param 和 filer 了
解析觸發自動構建的請求參數,ref和project.git_ssh_url是差異性的東西,那就根據兩個來區分項目
有這上面的兩個post參數還不行,因為只是獲取到了對應的參數值
其實要想區分不同的項目也簡單,只要獲取到的ref還有url 和需要構建的項目分支和 git地址相同就構建,否則就不構建
optional filter提供的方式就是最簡單的正則匹配
Expression設置為 ^(refs/heads/master)_(git@gitee.com:xiaochangwei/ci-demo.git)$ 注意修改為自己的項目地址
Text 設置為 $ref_$project.git_ssh_url
保存,再次構建,是不是只觸發了一個項目了,而不是所有項目了
測試:
1.提交代碼, 提交代碼后看到jenkins就自動編譯打包了
2.查看編譯日志:jenkins收到了webhook請求,并且拉取了代碼,提交信息和我們提交代碼時輸入信息一致
有同學質疑我這里為啥失敗了,是不是自動構建不可用,不是哈, 我這里是用的阿里服務器,內存不夠導致了自動發布失敗
完整編譯并正確部署的日志如下:
