#### 准备工作
```sh
jenkins 安装pipeline相关插件
```
#### 工作流程
##### springboot微服务打包工作流程
```sh
1.jenkins拉取gitlab代码
2.maven编译微服务打包生成jar包
3.docker build通过DockerFile文件把jar包打成镜像
4.docker push推送镜像到harbor仓库
5.helm部署会拉取harbor的服务镜像以及chart部署K8S集群
6.配置ingress暴露前端服务和API接口服务、网关服务
```
pipeline配置
```Groovy

REGISTRY_SECRET = 'shudoon-harbor-secret' #k8s存储私有仓库的secret
FILEBEAT_IMAGE="filebeat" #指定filebeat镜像名
SKYWALKING_IMAGE="skywalking-agent-sidecar" #指定skywalking镜像名
HELM_LOCAL_REPO = 'shudoon-local' #helm本地仓库名
HELM_TEMPLATE_NAME = 'springboot-demo' #helm的模板名
HELM_TEMPLATE_VERSION = '0.2.24-filebeat-skywalking-javaheap' #helm模板的版本

##### 前端服务打包工作流程
```sh
1.jenkins拉取gitlab代码
2.npm build构建前端代码生成dist静态文件

3.docker push推送镜像到harbor仓库
4.helm部署会拉取harbor的服务镜像以及chart部署K8S集群
5.配置ingress暴露前端服务和API接口服务、网关服务
