node节点pod网络报错“cni0“ already has an IP address different from

node节点pod无法启动/节点删除网络重置"cni0" already has an IP address different from

node1之前反复添加过,添加之前需要清除下网络

# kubectl get pod -n kube-system -o wide|grep tiller

在Node上执行如下操作：

重置kubernetes服务，重置网络。删除网络配置，link

kubeadm reset
systemctl stop kubelet
systemctl stop docker
rm -rf /var/lib/cni/
rm -rf /var/lib/kubelet/*
rm -rf /etc/cni/
ifconfig cni0 down
ifconfig flannel.1 down
ifconfig docker0 down
ip link delete cni0
ip link delete flannel.1
systemctl start docker
systemctl start kubelet

获取master的join token

kubeadm token create --print-join-command

重新加入节点

kubeadm join 10.6.76.26:6443 --token iweubu.ebjsywhlaklmgjep     --discovery-token-ca-cert-hash sha256:f03b27e002e77fcec510e057385ce382c02171b7f28d71ac95d8ac0f7c7330b1
