【问题描述】：
我在 centos7 虚拟机上安装了 minikube 集群。安装后，由于不健康的 pod 状态，很少有 pod 正在重新启动。所有失败的 pod 都有类似的原因：
来自 pod 的错误（描述命令）：
Readiness probe failed: Get "http://172.17.0.4:6789/readyz": dial tcp 172.17.0.4:6789: connect: connection refused
Liveness probe failed: Get "http://172.17.0.4:6789/healthz": dial tcp 172.17.0.4:6789: connect: connection refused
Liveness probe failed: HTTP probe failed with statuscode: 500
Readiness probe failed: HTTP probe failed with statuscode: 500
Liveness probe failed: HTTP probe failed with statuscode: 503
由于这些错误，pod 中的应用程序无法正常工作。 我是 kubernates 新手，无法理解调试此错误
UPDATE请看下方pod(che-operator)的错误日志

您能提供一种重现此错误的方法吗？最好查看到目前为止您已采取的确切步骤。您究竟是如何安装 Minikube 的？在尝试安装 eclipse-che 之前，您是否尝试过在其上运行其他任何东西，例如简单的 nginx pod？
-
mkdir kube cd kube curl -LO "dl.k8s.io/release/$(curl -L -s dl.k8s.io/release/stable.txt)/bin/linux/amd64/kubectl" curl -LO "dl.k8s.io/$(curl -L -s dl.k8s.io/release/stable.txt)/bin/linux/amd64/kubectl.sha256" curl -LO storage.googleapis.com/minikube/releases/latest/… sudo install minikube-linux-amd64 /usr/local/bin/minikube chmod u+x kubectl minikube start --addons=ingress --vm=true --memory=8192 --driver=none minikube kubectl –get po -A chectl server：部署 --platform minikube
-
你知道如何在operator pod上禁用leader选举
-
很遗憾无法帮助您解决这个问题，这是否与主要问题有关？也许你已经设法解决了？
