k8s执行crictl images报错

FATA0000 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
