containerd执行命令错误

原本安装kubernetes 1.24.1版本的集群来着，因为1.24.1版本的kubernetes需要用到containerd，而且containerd已经安装好了，但是在执行命令的时候报错了，这个和我们使用docker的时候不太一样，看一下下面的错误信息。

 WARN[0000] image 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.
 ERRO[0000] validate service connection: CRI v1 image API is not implemented for endpoint "unix:///var/run/dockershim.sock": rpc error: code = Unimplemented desc = unknown service runtime.v1.ImageService
 ERRO[0000] validate service connection: CRI v1 image API is not implemented for endpoint "unix:///run/containerd/containerd.sock": rpc error: code = Unimplemented desc = unknown service runtime.v1.ImageService
 E0801 13:34:05.027123    5775 remote_image.go:119] "ListImages with filter from image service failed" err="rpc error: code = Unavailable desc = connection error: desc = \"transport: Error while dialing dial unix /run/crio/crio.sock: connect: no such file or directory\"" filter="&ImageFilter{Image:&ImageSpec{Image:,Annotations:map[string]string{},},}"
 FATA[0000] listing images: rpc error: code = Unavailable desc = connection error: desc = "transport: Error while dialing dial unix /run/crio/crio.sock: connect: no such file or directory"

没看懂，就是提示找不到containerd的sock文件，这里需要在配置文件中指定一下。

 [root@www.wulaoer.org ~]# cat /etc/crictl.yaml
 runtime-endpoint: "unix:///var/run/containerd/containerd.sock"
 image-endpoint: ""
 timeout: 0
 debug: false
 pull-image-on-create: false
 disable-pull-on-run: false

在指定的文件中添加上面的内容，然后重启，在看一下命令结果，没有在提示找不到sock文件了。

 [root@www.wulaoer.org ~]# systemctl restart containerd
 [root@www.wulaoer.org ~]# crictl images
 FATA[0000] validate service connection: CRI v1 image API is not implemented for endpoint "unix:///var/run/containerd/containerd.sock": rpc error: code = Unimplemented desc = unknown service runtime.v1.ImageService

这个错误需要在/etc/containerd/config.toml文件中指定。

然后继续重启，在执行crictl images就不会有提示了，这个因为刚接触，所以只是写一个解决方法。
