零：场景复现：pod：calico-node异常

主节点：安装coredns -> init初始化 主节点（此时还没有安装calico）
从节点：基于主节点生成join命令加入集群
主节点：安装calico：apply 生成pod，此时没有调整yaml网卡
coredns 和calico pod 运行成功
但是 calico-node-cl8f2 运行失败

一：查看异常日志：主从节点[主要从节点]：journalctl -f -u kubelet

1.1：主节点：journalctl -f -u kubelet

[root@sv-master ~]# journalctl -f -u kubelet

1.2：从节点：journalctl -f -u kubelet

[root@sv-slaver-on ~]# journalctl -f -u kubelet
4月 11 15:06:21 sv-slaver-one kubelet[5050]: E0411 15:06:21.113081    5050 server.go:302] "Failed to run kubelet" err="failed to run Kubelet: misconfiguration: kubelet cgroup driver: \"systemd\" is different from docker cgroup driver: \"cgroupfs\""

4月 11 15:06:21 sv-slaver-one systemd[1]: kubelet.service failed.

三：解决方式，主要是在主节点重启docker和k8s服务

3.1：执行命令

[root@10 docker]# systemctl restart docker
[root@10 docker]# systemctl daemon-reload
[root@10 docker]# systemctl restart kubelet

3.2：编辑calicoyaml文件网卡

 # Cluster type to identify the deployment type
 - name: CLUSTER_TYPE
   value: "k8s,bgp"
 # 主要添加下面两行
 - name: IP_AUTODETECTION_METHOD
   value: "interface=enp0s3"

3.3：再次查看nodes和pod

sv-slaver-one为主节点，配反了

[root@sv-slaver-one ~]# kubectl get pods -A
