【问题描述】：

在 CI 升级期间，我们不断收到Waiting: ImagePullBackOff。有人知道发生了什么吗？通过 kops 安装的 k8s 集群 1.6.2。在升级期间，我们执行kubectl set image，在过去 2 天中，我们看到以下错误 Failed to pull image "********.dkr.ecr.eu-west-1.amazonaws.com/backend:da76bb49ec9a": rpc error: code = 2 desc = net/http: request canceled Error syncing pod, skipping: failed to "StartContainer" for "backend" with ErrImagePull: "rpc error: code = 2 desc = net/http: request canceled"

【解决方案2】：

这可能是由已知的docker bug 引起的，其中在创建图层时将内容同步到磁盘之前发生关机。该修复程序包含在 docker v1.13 中。

解决方法是删除空文件并重新拉取图像。
