devops部署SpringCloud项目
环境说明
- 已经安装kubesphere的devops组件
- 安装教程可参考官方文档:https://v3-1.docs.kubesphere.io/zh/docs/pluggable-components/devops/
部署流程
创建DevOps工程
填写流水线信息
创建流水线
1 我们编写JenkinsFile
流水线的部署流程如下图
拉取代码 编译代码 打包镜像 推送镜像 部署应用
jenkinsfile
因为所有服务都写出来实在太长也不方便观看,故以
gateway,admin两个模块为例,增加其他模块也是亦是相同,复制粘贴即可

打包镜像文件

COPY target/*.jar /app.jar
EXPOSE 8080
ENTRYPOINT ["/bin/sh","-c","java -Dfile.encoding=utf8 -Djava.security.egd=file:/dev/./urandom -jar app.jar ${PARAMS}"]deploy.yaml
