k8s执行crictl images报错
FATA[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
解决方法：
vim /etc/containerd/config.toml
找到runtime_type 写入"io.containerd.runtime.v1.linux"
[plugins."io.containerd.grpc.v1.cri".containerd.default_runtime]
base_runtime_spec = ""
cni_conf_dir = ""
cni_max_conf_num = 0
container_annotations = []
pod_annotations = []
privileged_without_host_devices = false
runtime_engine = ""
runtime_path = ""
runtime_root = ""
runtime_type = "io.containerd.runtime.v1.linux"
最后重启服务：
[root@master ~]# systemctl restart containerd
