coredns无法正常运行

一.问题现象

启动zookeeper,redis,进入业务pod无法ping zookeeper,ping redis

二.解决方案

1.修改所有k8s node的/etc/kubernetes/kube-proxy.config.yaml ，将

clusterCIDR: 171.22.0.0/16改成正确的值，171.22.0.0/16为pod的网段

apiVersion: kubeproxy.config.k8s.io/v1alpha1

bindAddress: 10.81.44.112

clientConnection:

 kubeconfig: /etc/kubernetes/kube-proxy.kubeconfig

clusterCIDR: 171.22.0.0/16

healthzBindAddress: 10.81.44.112:10256

hostnameOverride: 10.81.44.112

kind: KubeProxyConfiguration

metricsBindAddress: 10.81.44.112:10249

mode: "ipvs"

2.重启所有k8s node的kube-proxy

service kube-proxy
