k8s无法进入容器报错和解决方法

如报错： Error from server: error dialing backend: dial tcp: lookup k8s-node2 on 8.8.8.8:53: no such host Error from server: error dialing backend: dial tcp 192.168.2.192:10250: connect: connection refused 此故障是hosts文件解析名称和节点主机名称，以及配置文件kube-proxy.kubeconfig不一致所导致此问题

#配置文件kube-proxy.kubeconfig里面此名称hostnameOverride: k8s-node01和主机名称不一致 kind: KubeProxyConfiguration apiVersion: kubeproxy.config.k8s.io/v1alpha1 address: 0.0.0.0 metricsBindAddress: 0.0.0.0:10249 clientConnection: kubeconfig: /opt/kubernetes/cfg/kube-proxy.kubeconfig hostnameOverride: k8s-node01 clusterCIDR: 10.0.0.0/24 mode: ipvs ipvs: scheduler: “rr” iptables: masqueradeAll: true ~

#修改hosts解析 192.168.2.190 k8s-master 192.168.2.191 k8s-node1 192.168.2.192 k8s-node2 192.168.2.193 k8s-node3

#修改主机名称 hostnamectl set-hostname k8s-master hostnamectl set-hostname k8s-node1 hostnamectl set-hostname k8s-node2 hostnamectl set-hostname k8s-node3

#重启node节点的组件 systemctl restart kubelet systemctl restart kube-proxy
