docker利用WebHook實(shí)現(xiàn)持續(xù)集成

更新時間：2018年01月12日 12:12:25 作者：肖哥哥

這篇文章主要介紹了docker利用WebHook實(shí)現(xiàn)持續(xù)集成的相關(guān)知識，非常不錯，具有參考借鑒價值,需要的朋友可以參考下

研發(fā)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(fā)布

在項(xiàng)目調(diào)試測試階段，可能經(jīng)常需要重復(fù)上面的步驟，以便將最新代碼部署到特定環(huán)境供測試人員或其他人員使用

CI即持續(xù)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(fā)jenkins打包并發(fā)布到相應(yīng)容器中，開發(fā)人員只需提交代碼，后續(xù)打包發(fā)布都自動實(shí)現(xiàn)

配置好環(huán)境后，在tomcat中運(yùn)行jenkins，并設(shè)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(fā)布到docker中，通過Deploy to container Plugin發(fā)布到tomcat中的

2.上傳maven項(xiàng)目到https://gitee.com

3.jenkins中新建項(xiàng)目ci

　　3.1 配置提交的代碼地址，Add有權(quán)限的用戶名和密碼（我的是私有項(xiàng)目），指定分支

　　3.2：配置maven命令以及發(fā)布到的tomcat

　　注意：發(fā)布項(xiàng)目的tomcat需要設(shè)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(gòu)建項(xiàng)目了，請確保手動構(gòu)建能成功后再進(jìn)行下列操作

　　遇見的問題及解決方案：

　　　　如果構(gòu)建時提示權(quán)限不對

　　　　生成公鑰： ssh-keygen -t rsa 一直回車直結(jié)束

　　　　cat ~/.ssh/id_rsa.pub 將內(nèi)容增加到碼云上

　　　　如果還提示沒權(quán)限

　　　　手動先在jenkins運(yùn)行的機(jī)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(gòu)建，應(yīng)該就能成功了

　　至此，手動打包并部署就已經(jīng)實(shí)現(xiàn)了

　　------------------------------自動部署 --------------------------------------------------

　　1. 安裝上述插件后勾選Generic Webhook Trigger 增加post參數(shù) ref expression值為 $.ref 注意有個點(diǎn)

　　增加optional filter

　　其實(shí)上面這部分不用設(shè)置也行，尤其是只會在jenkins中部署一個項(xiàng)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(diǎn)擊用戶名-api token)

　　　　同時勾選push或者其他你認(rèn)為需要觸發(fā)部署的事件

　　提交后點(diǎn)擊測試，如果返回ok，則表示成功，切換到j(luò)enkins，查看項(xiàng)目是否能夠自動部署

　　我自己寫了一個接口用來獲取點(diǎn)擊測試后，到底請求了些什么　　

　　　　格式化下內(nèi)容如下：

　　其實(shí)多建立幾個項(xiàng)目然后獲取信息后會發(fā)現(xiàn)，不同項(xiàng)目間存在差異的就是project.git_ssh_url 和分支 ref

　　至此，單個項(xiàng)目的自動部署就完了

　　如果你在jenkins中有多個項(xiàng)目，你觸發(fā)其中的一個webHook你就會發(fā)現(xiàn)，所有的項(xiàng)目都在構(gòu)建？

　　這就有點(diǎn)不科學(xué)了，本來只想構(gòu)建A項(xiàng)目，結(jié)果Abc項(xiàng)目都構(gòu)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(fā)自動構(gòu)建的請求參數(shù)，ref和project.git_ssh_url是差異性的東西，那就根據(jù)兩個來區(qū)分項(xiàng)目

　　有這上面的兩個post參數(shù)還不行，因?yàn)橹皇谦@取到了對應(yīng)的參數(shù)值

　　其實(shí)要想?yún)^(qū)分不同的項(xiàng)目也簡單，只要獲取到的ref還有url 和需要構(gòu)建的項(xiàng)目分支和 git地址相同就構(gòu)建，否則就不構(gòu)建

　　optional filter提供的方式就是最簡單的正則匹配

　　Expression設(shè)置為 ^(refs/heads/master)_(git@gitee.com:xiaochangwei/ci-demo.git)$ 注意修改為自己的項(xiàng)目地址

　　Text 設(shè)置為　　　$ref_$project.git_ssh_url

　　保存，再次構(gòu)建，是不是只觸發(fā)了一個項(xiàng)目了，而不是所有項(xiàng)目了

　　測試：

　　　　1.提交代碼，提交代碼后看到j(luò)enkins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(xué)質(zhì)疑我這里為啥失敗了，是不是自動構(gòu)建不可用，不是哈，我這里是用的阿里服務(wù)器，內(nèi)存不夠?qū)е铝俗詣影l(fā)布失敗

　　　　完整編譯并正確部署的日志如下：
