[系统运维]Jenkins连接k8s新姿势

由于Jenkins新版的对 Kubernetes Continuous Deploy这个插件不太友好。官网提供的新版本一直出现bug无法执行 Deploy，可以用以下我的这个老插件,不要更新新插件即可

配如下

1.方式获取k8s密钥
cat .kube/config 
2.导出方式或者密钥
kubectl config view --raw > k8s-config-admin 

配置Jenkins连接k8s

确保可以连接

最后再配置Deploy 执行yaml,这步不用我多说了吧

最少一条pipeline也不用多说了吧,

pipeline {
  agent {
    kubernetes {
      yaml '''
