kubernetes - Istio Bookinfo k8 部署

Question

我有一个主节点和两个工作节点（worker-1 和 worker-2）。所有节点都已启动并运行，没有任何问题。当我计划安装 istio 服务网格时，我尝试部署示例书信息部署。

部署 bookinfo 后，我验证了在命令下运行的 pod 状态

root@master:~# kubectl get pod -o wide
NAME                              READY   STATUS    RESTARTS   AGE   IP               NODE       NOMINATED NODE   READINESS GATES

我注意到两个 pod 没有在这里运行状态显示 1/2（在 worker-2 节点中），我几乎花了两天时间但找不到任何东西来解决上述问题。这里是描述 pod 状态

Warning  Unhealthy  63s (x14 over 89s)  kubelet            Readiness probe failed: Get "http://10.244.133.194:15021/healthz/ready": 
dial tcp 10.200.133.194:15021: connect: connection refused

然后今天早上我意识到当 pod 没有以 1/2 状态运行时，worker-2 节点出现了问题，我计划了如下所示的警戒节点

kubectl cordon worker-2
kubectl delete pod <worker-2 pod>
kubectl get pod -o wide

在封锁 worker-2 节点之后，我可以看到所有 pod 在 worker-1 节点中的状态为 2/2，没有任何问题。

root@master:~# kubectl get pod -o wide

您能否请有人帮我解决这个问题，以便在 worker-2 节点中安排（待处理的 pod）pod。

注意：当我尝试重新部署所有节点（worker-1 和 worker-2）时，pod 状态又回到 1/2 状态
