Question

我使用了默认安装（用于Windows的docker上的kubernetes）：

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

编辑：

Answer 1

我试图在Windows版Docker的Kubernetes上完成这项工作，但无法完成。 Windows中的卷似乎有些问题。我尝试过修改路径，但没有实际效果。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在PV的基础上添加了1 Gi，但随后出现了有关路径断开的错误。无论如何仍然不走运。由于我不是Windows方面的专家，因此似乎是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和通过kubadm连接的计算引擎上进行了测试，该图表在没有任何其他配置的情况下就像一个超级按钮一样工作。）

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。

Answer 2

我遇到了同样的问题，并在一篇文章中提到该问题是由于Windows目录在Docker容器内作为通用Internet文件系统（CIFS）挂载而引起的。 Linux上的SQL Server尚未正式将CIFS作为文件系统支持。

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

我通过使用针对Linux的较新版本的sql server来解决了该问题

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

我安装了掌舵图表稳定版/ mssql-linux，“ pod具有未绑定的PersistentVolumeClaims”
