containerd是轻量化的运行容器，类似于docker，目前是K8S推荐的首选运行容器

runtime connect using default endpoints: [unix:///var/run/dockershim.sock unix:///run/containerd/containerd.sock unix:///run/crio/crio.sock unix:///var/run/cri-dockerd.sock]. As the default settings are now deprecated, you should set the endpoint instead.

# 未运行前
crictl config runtime-endpoint unix:///var/run/cri-dockerd.sock
# containerd 以运行后 ()
crictl config runtime-endpoint unix:///var/run/containerd/containerd.sock
crictl ps -a

FATA[0000] validate service connection: CRI v1 runtime API is not implemented for endpoint “unix:///var/run/containerd/containerd.sock”: rpc error: code = Unimplemented desc = unknown service runtime.v1.RuntimeService

#如果看到了这行：
disabled_plugins : ["cri"]

#将这行用#注释或者将"cri"删除
#disabled_plugins : ["cri"]
 
disabled_plugins : []
#重启容器运行时
