在使用crictl ps查看pod中container的时候报错如下，主要是因为container runtime是containerd，可以通过设置runtime-endpoint来解决错误
root@k8sdbaworker1:/etc/containerd# crictl ps
WARN[0000] 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.
