Database gcloud问题，永久卷运行OracleDB Docker映像（权限被拒绝）

我试图在gcloud kubernetes中运行Oracle DB enterprise（docker store的最新OEM映像）。然而，我找不到这种跑步的例子，我是一个遇到很多错误的noob

使用以下部署代码，我可以部署映像，但当容器引导并尝试设置数据库时，我遇到了问题。当容器尝试设置数据库默认值（u01文件系统等）时，我从容器日志中获得了拒绝的权限。这意味着容器进入一个无限的引导循环，试图缝合自身。我可以在docker中正常运行映像，并将其作为默认部署（没有持久性存储，即仅按原样部署映像），但问题是当我尝试装载持久性存储卷时。就像我说的，我是一个完全的NOOB，所以我只是尝试从我在其他dbyaml示例中看到的内容创建一个工作脚本。我得到了概念，但无法让脚本工作。下面有注释掉的代码也不会在gcloud中运行（它验证并从kubectl运行，但gcloud挂起试图进行配置）

请帮忙

您需要一个

initContainer:

，如本文所述，以确保NFS目录由容器用于

oracle

的UID所有。严格地说，我实际上只希望您必须这样做一次，但在任何Pod start上运行它也不会有任何伤害，只要您不使用我在回答中（可能错误地）建议的

chown-R

。对于只有几个文件的卷来说，这是可以的，但是如果该卷中填充了数百个文件，那么Pod的开始时间就会受到真正的拖累

另外，我已经有一段时间不必使用oracle了，但在尝试在NFS上运行数据库时我会非常谨慎。那

gce-pd

更可能按照您的意愿运行，特别是如果gce像AWS一样提供了配置的IOPS

最后，请不要为oracle使用

部署

：您需要一个，因为Pod的标识很可能在启动时与所连接的文件系统紧密耦合。

谢谢，这为我提供了很多尝试并使其工作的方向
