PostgreSQL在Kubernetes上的卷权限错误 [英] postgres on kubernetes volume permission error

问题描述

我正在尝试在GKE上部署postgres / postgis，但是我继续收到权限错误： initdb：无法更改目录 / var / lib / postgresql / data的权限：操作不允许。我尝试了各种研究过的修复程序，但尚未通过此错误。以下是我的部署Yaml。

I'm trying to deploy postgres/postgis on GKE, but I continue to get the permission error: initdb: could not change permissions of directory "/var/lib/postgresql/data": Operation not permitted. I've tried various fixes that I've researched but I've yet to get passed this error. Below is my deployment yaml.

我丢失了什么？

          volumeMounts:

              subPath: data

推荐答案

虽然问题不完全相同，但这是使用 initContainer：到 chmod 答案将使您感兴趣：小丑：更改'/ data / db'的所有权：不允许进行操作

While it is not exactly the same question, this "use an initContainer: to chmod" answer will interest you: chown: changing ownership of '/data/db': Operation not permitted
