K8S 通过etcd恢复错误节点的网络信息

以下操作均不能执行 export ETCDCTL_API=3

etcdctl --endpoints=https://192.168.0.219:2379,https://192.168.0.220:2379,https://192.168.0.221:2379 --ca-file=/etc/kubernetes/ssl/k8s-root-ca.pem --cert-file=/etc/kubernetes/ssl/kubernetes.pem --key-file=/etc/kubernetes/ssl/kubernetes-key.pem ls /kubernetes/network/subnets/ (etcdv2查看节点网络信息）

etcdctl --endpoints=https://192.168.0.219:2379,https://192.168.0.220:2379,https://192.168.0.221:2379 --ca-file=/etc/kubernetes/ssl/k8s-root-ca.pem --cert-file=/etc/kubernetes/ssl/kubernetes.pem --key-file=/etc/kubernetes/ssl/kubernetes-key.pem rm /kubernetes/network/subnets/xxxx （etcdv2 删除错误网络节点的信息）

删除错误节点/run/flannel 下的所有文件

同事重启apiserver 和 错误节点的flanneld

//flannel network配置

# etcdctl --endpoints http://127.0.0.1:{etcd listen port} get /coreos.com/network/config

{"Network":"172.16.0.0/16", "Backend": {"Type": "vxlan"}}

# etcdctl --endpoints http://127.0.0.1:{etcd listen port} ls /coreos.com/network/subnets

/coreos.com/network/subnets/172.16.99.0-24

/coreos.com/network/subnets/172.16.57.0-24

//某一node上的flanne subnet和vtep配置

# etcdctl --endpoints http://127.0.0.1:{etcd listen port} get /coreos.com/network/subnets/172.16.99.0-24

{"PublicIP":"{master node ip}","BackendType":"vxlan","BackendData":{"VtepMAC":"b6:bf:4c:81:cf:3b"}}

minion node:

# etcdctl --endpoints http://127.0.0.1:{etcd listen port} get /coreos.com/network/subnets/172.16.57.0-24

{"PublicIP":"{minion node ip}","BackendType":"vxlan","BackendData":{"VtepMAC":"d6:51:2e:80:5c:69"}}
