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
:

hostnameOverride:
10.81

44.112
kind: KubeProxyConfiguration
metricsBindAddress:
10.81

2.重启所有k8s node的kube-proxy
service kube-proxy
