拉取 MS SQL Server 的公共映像时，Kubernetes 中的 pod 上出现“上下文截止时间已过”错误

关注 Les Jackson教程在微服务上，在启用了 Kubernetes 的 Docker 本地安装上，我想在 Kubernetes 中创建一个新的 pod，其中包含可用的 ms sql server express 映像这里。部署文件与视频中的完全相同，但我无法让它工作。每次 pod 都以状态 ImagePullBack 结束。运行后kubectl 描述 pod：

我发现了潜在的错误

“rpc 错误：代码 = 未知 desc = 超出上下文截止时间”

而且我不确定如何进一步解决此问题，我将非常感谢任何帮助。

我最初在 stackoverflow 上发布了此内容这里并将我的问题重定向到此站点，因为这可能是网络问题。

答案1

我通过运行docker pull mcr.microsoft.com/mssql/server:2017-latest、删除并重新应用部署来修复它。

答案2

同样的问题，但我需要先将图像拉到 minikube minikube ssh docker pull <the_image>

然后部署就可以了
