声明式pipeline在k8s中完成自动部署，回滚，钉钉通知

jenkins gitlab nexus3/harbor 此类清单已有，安装部署不再叙述

Github: https://github.com/alexclownfish/jenkins_pipline 资源清单均在以上github地址

• 版本发布失败/成功推送钉钉
• 版本回滚成功/失败推送钉钉
• 构建stage过程成功/失败推送钉钉

jenkins 所需插件

网络延迟大下载慢，可以到下边地址下载，再load到jenkins https://updates.jenkins-ci.org/download/plugins/

Docker plugin
Kubernetes plugin
Kubernetes CLI Plugin
DingTalk
GitLab Plugin
Localization: Chinese (Simplified)

kubernetes clouds 配置

添加kubernetes clouds

Pod Templates

jenkins-slave

maven-3.6

docker-and-maven 继承maven-3.6，挂载docker.sock以便后续docker.build

kubectl (用于kubectl apply 滚动更新)

docker-and-maven-and-kubectl 继承docker-and-maven

pipeline to dingding

凭据

Job 配置

参数化构建 （版本回滚）

pipeline as vscode

将pipeline 以Jenkinsfile形式存放到代码仓库

配置Pipeline script from SCM （pipeline从代码仓库检出）
