k8s 1.21.1部署过程中calico服务启动失败问题
#此场景只是calico启动失败的其中一个场景
问题描述：
OCI runtime create failed: container_linux.go:318: starting container process caused "process_linux.go:281: applying cgroup configuration for process caused "No such device or address"": unknown
解：
1、将/etc/docker/daemon.json和/etc/kubernetes/kubeletconfig中的驱动从systemd改为cgroupfs
2、systemctl daemon-reload
systemctl restart docker
