docker利用WebHook实现持续集成

2021-02-07 23:29肖哥哥 服务器知识

这篇文章主要介绍了docker利用WebHook实现持续集成的相关知识,非常不错,具有参考借鉴价值,需要的朋友可以参考下

研发小伙伴可能对下列操作步骤会深有体会

写代码--》提交代码--》打包--》发布

在项目调试测试阶段,可能经常需要重复上面的步骤,以便将最新代码部署到特定环境供测试人员或其他人员使用

ci即持续集成的提出及各种解决方案,减轻了很多最初简单但繁琐的工作

本文将通过提交代码到git,然后通过webhook触发jenkins打包并发布到相应容器中,开发人员只需提交代码,后续打包发布都自动实现

git  :我使用的码云   我的主页为: https://gitee.com/xiaochangwei

jenkins:jenkins ver. 2.89.2

配置好环境后,在tomcat中运行jenkins,并设置好用户名密码确保能正常登录使用

docker利用WebHook实现持续集成

操作步骤:

1.安装插件   generic webhook trigger plugin、deploy to container plugin、git plugin 由于这里暂时未发布到docker中,通过deploy to container plugin发布到tomcat中的

2.上传maven项目到https://gitee.com

3.jenkins中新建项目ci

  3.1 配置提交的代码地址,add有权限的用户名和密码(我的是私有项目),指定分支

docker利用WebHook实现持续集成

  3.2:配置maven命令以及发布到的tomcat

docker利用WebHook实现持续集成

  注意:发布项目的tomcat需要设置用户信息,即修改conf下的user.xml  具体可以参考我很早之前写的http://www.cnblogs.com/xiaochangwei/p/4952644.html

       这样就可以手动构建项目了,请确保手动构建能成功后再进行下列操作

  遇见的问题及解决方案:

    如果构建时提示权限不对

    生成公钥:  ssh-keygen -t rsa  一直回车直结束

    cat ~/.ssh/id_rsa.pub   将内容增加到码云上

docker利用WebHook实现持续集成

    如果还提示没权限

    手动先在jenkins运行的机器上clone一次代码  如 git clone  git@gitee.com:xiaochangwei/ci-demo.git  注意输入yes

docker利用WebHook实现持续集成

    然后再看.ssh目录,多了一个known_hosts 里面有码云了,然后再手动构建,应该就能成功了

docker利用WebHook实现持续集成

  至此,手动打包并部署就已经实现了

  ------------------------------自动部署 --------------------------------------------------

  1. 安装上述插件后勾选generic webhook trigger 增加post参数 ref  expression值为 $.ref   注意有个点

docker利用WebHook实现持续集成

  增加optional filter

docker利用WebHook实现持续集成

  其实上面这部分不用设置也行,尤其是只会在jenkins中部署一个项目的一个分支时,只需要勾选上generic webhook trigger就可以的

  2. 在码云中增加hook:http://user id:api token@jenkins部署的地址:端口号/jenkins/generic-webhook-trigger/invoke (红色这部分不要变)

    (这里不用api token 直接用jenkins的登录密码也可以, api token查看地址为:jenkins-用户-点击用户名-api token)

    同时勾选push或者其他你认为需要触发部署的事件

docker利用WebHook实现持续集成

  提交后点击测试,如果返回ok,则表示成功,切换到jenkins,查看项目是否能够自动部署

  我自己写了一个接口用来获取点击测试后,到底请求了些什么

  其实多建立几个项目然后获取信息后会发现,不同项目间存在差异的就是project.git_ssh_url 和分支 ref

  至此,单个项目的自动部署就完了

  如果你在jenkins中有多个项目,你触发其中的一个webhook你就会发现,所有的项目都在构建?

  这就有点不科学了,本来只想构建a项目,结果abc项目都构建了?  要解决这个就需要用到上面提到的post param 和 filer 了

  解析触发自动构建的请求参数,ref和project.git_ssh_url是差异性的东西,那就根据两个来区分项目

docker利用WebHook实现持续集成

  有这上面的两个post参数还不行,因为只是获取到了对应的参数值

  其实要想区分不同的项目也简单,只要获取到的ref还有url 和需要构建的项目分支和 git地址相同就构建,否则就不构建

  optional filter提供的方式就是最简单的正则匹配

docker利用WebHook实现持续集成

  expression设置为  ^(refs/heads/master)_(git@gitee.com:xiaochangwei/ci-demo.git)$注意修改为自己的项目地址

  text 设置为   $ref_$project.git_ssh_url

  保存,再次构建,是不是只触发了一个项目了,而不是所有项目了

  测试:

    1.提交代码, 提交代码后看到jenkins就自动编译打包了

     2.查看编译日志:jenkins收到了webhook请求,并且拉取了代码,提交信息和我们提交代码时输入信息一致      

    有同学质疑我这里为啥失败了,是不是自动构建不可用,不是哈, 我这里是用的阿里服务器,内存不够导致了自动发布失败

    完整编译并正确部署的日志如下:
