【发布时间】：2019-03-06 00:18:42
【问题描述】：

我用的是默认安装（windows上的kubernetes on docker）：

helm install --name mymssql stable/mssql-linux --set acceptEula.value=Y --set edition.value=Developer

我可以看到持久卷存在

但是

【问题讨论】：

  • 你能给出 Kubectl describe pvc , kubectl describe pv kubectl describe storgeclass 的输出吗？
  • 嗨@karthik，我添加了这个。谢谢
  • 嗨，我有类似的问题，我正在努力解决。请提供kubectl describe pod sql_podname的结果

标签： kubernetes kubernetes-helm docker-for-windows docker


【解决方案1】：

我尝试在 Docker for Windows 上的 Kubernetes 上完成这项工作，但我无法完成它。似乎 Windows 中的卷存在一些问题。我试过修补路径，但没有真正的效果。一段时间后，我注意到卷的大小存在问题，因此我下载了图表并将 1 Gi 添加到 PV，但随后我收到有关损坏路径的错误。反正还是倒霉。 因为我不是 Windows 专家，这似乎是 Windows 或应用程序问题。我只能建议使用其他方式运行图表（我在 ubuntu 上的 Minikube、GKE 和由 kubadm 连接的计算引擎上对其进行了测试，图表就像一个魅力一样工作，无需任何额外配置）。

如果您想继续尝试运行kubectl logs pod_name 并按照那里描述的问题进行操作。

【讨论】：

  • 不幸的是，我遇到了同样的情况，并且似乎没有我正在映像的日志，因为它还没有成功启动。
  • 你可以试试 GKE 或 minikube，在那里运行没有问题。就我而言，我能够从 pod 访问日志。您可以尝试在新主题中更广泛地描述您的问题，我们可以尝试进行故障排除。
【解决方案2】：

我遇到了同样的问题，并且偶然看到一篇文章，该文章解释了该问题是由于 Windows 的目录作为通用 Internet 文件系统 (CIFS) 安装在 Docker 容器内而引起的。 Linux 上的 SQL Server 不正式支持 CIFS 作为文件系统。

https://support.microsoft.com/en-us/help/4212960/fix-sql-server-2017-won-t-start-with-linux-container-image-on-docker

我通过使用更新版本的 sql server for linux 解决了这个问题

helm install mymssql stable/mssql-linux --set acceptEula.value=Y --set edition.value=Developer --set service.type=LoadBalancer --set image.repository=mcr.microsoft.com/mssql/server --set image.tag=2019-latest
