如何解决执行crictl命令报错的问题

安装了 containerd 启动容器，执行 crictl 命令是报错，提示如下信息：

WARN[0000] image connect using default endpoints: [unix:///var/run/dockershim.sock unix:///run/containerd/containerd.sock unix:///run/crio/crio.sock]. As the default settings are now deprecated, you should set the endpoint instead. 
ERRO[0002] connect endpoint 'unix:///var/run/dockershim.sock', make sure you are running as root and the endpoint has been started: context deadline exceeded

crictl执行命令时默认会去 /var/run/dockershim.sock 找 sock 文件，如果没有这个文件，则会提示报错。

1.创建 crictl 配置文件

cat /etc/crictl.yaml 
runtime-endpoint: unix:///run/containerd/containerd.sock
image-endpoint: unix:///run/containerd/containerd.sock
timeout: 5
debug: false

2.执行命令测试

crictl images list
