持续集成：自动部署打包发布代码
Jenkins工作流程
项目已经基于Jenkins实现了持续集成，每当我们push代码时，就会触发项目完成自动编译和打包。而需要运行某个微服务时，我们只需要经过两步：
- 第一步，访问jenkins控制台
- 第二步，点击对应微服务后面的运行按钮
进入nacos可以看到服务启动了。
1) 当代码提交时 触发web钩子(一个url地址的自动调用叫web钩子):
http://192.168.150.101:18080/gogs-webhook/?job=tjxt-dev-build
2) jenkins 的任务 tjxt-dev-build被触发
3) tjxt-dev-build 任务会自动拉取: git 代码:
jenkins 会自动把代码拉取到 /usr/local/src/jenkins/workspace/tjxt-dev-build (对应的任务文件夹下)
4) 自动构建 lesson-init 分支 (编译打包)
5) 构建完成后 执行了如下的指令
ssh root@192.168.150.101 "cd /usr/local/src/script && rm -rf * && cp ../jenkins/workspace/tjxt-dev-build/Dockerfile . && cp ../jenkins//tjxt-dev-build/startup.sh . && chmod a+x startup.sh"
5.1) 进入 /usr/local/src/script
5.2) 删除所有东西
5.3) 复制 ../jenkins/workspace/tjxt-dev-build/Dockerfile 到 上述目录
5.4) 复制 ../jenkins//tjxt-dev-build/startup.sh 到 上述目录
5.5) 并给予 startup.sh 可执行权限(所有用户)
测试流程
-
push代码 到远程git仓库
-
查看仓库的代码提交记录
- 查看web钩子上的Jenkins任务构建历史
查看虚拟机中Jenkins修改的文件
附Dockerfile和startup.sh
目前我看不太懂，只能请求某chat解释一下
