我的K8S集群在启动一个POD的时候说死起不来，然后就报下面的错误

折腾了好久，解决方案就是注释掉，下面的行，然后你就可以helm upgrade了

$ cat templates/deployment.yaml
              #          livenessProbe:
              #            httpGet:
              #              path: /
              #              port: http
              #          readinessProbe:
              #            httpGet:
              #              path: /
              #              port: http

总结：Liveness 和readines这两个健康探针在使用时，你需要确保你的K8S集群中确实这两个服务
