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 = 0container_annotations = []pod_annotations = []privileged_without_host_devices = falseruntime_engine = ""runtime_path = ""runtime_root = ""runtime_type = "io.containerd.runtime.v1.linux"

最后重启服务：

[root@master ~]# systemctl restart containerd
