Kubernetes Pod对象在尝试使用PostgreSQL DB部署停靠的Django应用程序时在无限循环中崩溃

我正在进行Django项目，并试图将其部署到Kubernetes集群Google云提供商上。我已成功创建配置群集所需的所有文件：

Django应用程序部署+服务.yml文件 Postgres DB部署+服务+PersistentVolumeClaim，动态创建PersistentVolume对象并在上使用PD存储 默认情况下，云节点+Secret.yml文件 Docker File+Docker Compose我对Docker没有太多的经验，所以他们可能有问题，也许这就是问题所在 这个问题我想不出来 由于某种原因，当我尝试应用它们时，我的pod，特别是Django应用程序pod，正在无限循环中崩溃。此外，我的Postgres吊舱没有崩溃，但它没有运行

谁能帮我找出我做错了什么？这是我的github回购协议：

我最好的猜测是，我没有在settings.py文件中正确设置数据库配置，并且我的Django应用程序找不到settings.py中指定的数据库主机。如果有人有任何建议，请留下评论

这是我的Kubernetes吊舱列表的图片：

下面是我描述的第一个吊舱对象的图片：

*更新*

以下是我尝试运行python src/manage.py runserver时的错误消息：

---

您的应用程序无法连接到数据库，因为您的Postgres服务器无法启动。您有0/1个POD处于就绪状态

你没有发布它的Pod事件，但我想主要原因是它的数量

在您的Postgres规范中，我看到您将卷类型设置为 ReadWriteMany，但Google Cloud不提供这种类型的卷、路径访问模式，实际上，我看不出您需要它的原因。将类型更改为ReadWriteOnce并重新部署数据库，这应该会有所帮助

另外，要获取集群中应用程序的日志，可以调用kubectl logs$podname，这会更有帮助

---

P.P.S.发布文本信息时，请使用文本格式

你能分享pods的日志、kubectl为你的pods描述$pod命令的结果以及你节点的标签吗？我已经更新了这个问题。请看一看，谢谢你的帮助！
