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
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
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
3.2:配置maven命令以及发布到的tomcat
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
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
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
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
增加optional filter
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
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
格式化下内容如下:
{ hook_name: push_hooks, total_commits_count: 1, before: 0000000000000000000000000000000000000000, user_name: 肖哥哥, project: { path: ci-demo, git_svn_url: svn://gitee.com/xiaochangwei/ci-demo, path_with_namespace: xiaochangwei/ci-demo, name: ci-demo, namespace: xiaochangwei, default_branch: master, git_http_url: https://gitee.com/xiaochangwei/ci-demo.git, name_with_namespace: 肖哥哥/ci-demo, url: https://gitee.com/xiaochangwei/ci-demo, git_ssh_url: git@gitee.com:xiaochangwei/ci-demo.git }, repository: { name: ci-demo, description: , url: https://gitee.com/xiaochangwei/ci-demo.git, homepage: https://gitee.com/xiaochangwei/ci-demo }, commits_more_than_ten: false, ref: refs/heads/master, password: , commits: [{ author: { name: 肖哥哥, time: 2015-11-06T13:21:07+08:00, email: 317409898@qq.com }, id: ec7159240a346fa5988913aa3057b902a4acb126, message: A Test For WebHooks, url: https://gitee.com/xiaochangwei/ci-demo/commit/ec7159240a346fa5988913aa3057b902a4acb126, timestamp: 2015-11-06T13:21:07+08:00 }], after: ec7159240a346fa5988913aa3057b902a4acb126, user: { name: 肖哥哥, id: 372286, time: 2018-01-11T12:38:38+08:00, user: xiaochangwei, email: 317409898@qq.com, url: https://gitee.com/xiaochangwei } }
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
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
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:
