/var/lib/docker/overlay2：参数无效错误：启动 kubernetes pod 时出现 ImageInspectError

Question

今天我的 kubernetes 1.15 显示了这个错误：

\n

Failed to inspect image "registry.cn-hangzhou.aliyuncs.com/dabai_app_k8s/dabai-fat/soa-illidan-superhub:v1.0.3": rpc error: code = Unknown desc = Error response from daemon: readlink /var/lib/docker/overlay2: invalid argument\nError: ImageInspectError\n

我试图在本地计算机中提取图像：

工作正常，我尝试在远程 kubernetes 集群机器中拉取映像，工作正常。看来是 kubernetes 的问题，我该怎么解决呢？

我建议您首先停止 docker 引擎，systemctl stop docker然后使用rm -rf /var/lib/docker. 那么你应该用 再次启动 docker systemctl start docker。
