Nextcloud Kubernetes部署内部服务器错误

Question

我想根据这个指南在kubernetes中安装nextcloud：https://www.codementor.io/@alicheaito/deploying-nextcloud-on-kubernetes-with-kustomize-tn78vcz0a

我不使用任何入口。为了进行测试，我在部署时使用了RunAsUser: 0，我知道这是不安全的，我将在生产中将其更改为端口8080和用户id 1099。当我调用页面时，我会看到这个屏幕：

​

我在日志里看不到任何可疑的东西：

​

我是kubernetes的新手，我不知道从哪里开始调试。

我的nextcloud deployment.yaml：

apiVersion: apps/v1
kind: Deployment
metadata:
  labels:
    component: app
  name: app
spec:
  selector:
    matchLabels:
      component: app

  template:
    metadata:
      labels:
        component: app
    spec:
      securityContext:
        fsGroup: 1099
        runAsUser: 33
        runAsGroup: 1099
      containers:
        - image: nextcloud:apache
          imagePullPolicy: Always
          name: app
          ports:
            - containerPort: 80
          env:
            - name: MYSQL_DATABASE
              valueFrom:
                secretKeyRef:
                  key: MYSQL_DATABASE
                  name: db-secrets
            - name: MYSQL_PASSWORD
              valueFrom:
                secretKeyRef:
                  key: MYSQL_PASSWORD
                  name: db-secrets
            - name: MYSQL_USER
              valueFrom:
                secretKeyRef:
                  key: MYSQL_USER
                  name: db-secrets
          volumeMounts:
            - mountPath: /var/www/html
              name: app-persistent-storage
            - mountPath: /usr/local/etc/php/conf.d/
              name: app-persistent-storage
      restartPolicy: Always
      volumes:
        - name: app-persistent-storage
          persistentVolumeClaim:
            claimName: app-pvc

nextcloud的service.yaml：

apiVersion: v1
kind: Service
metadata:
  name: app
  labels:
    component: app
spec:
  type: LoadBalancer
  ports:
    - port: 80
  selector:
    component: app

来自服务和pods的截图：

这是nextcloud.log文件，其中有一些可疑的东西，但这对我没有帮助：

让我来解决你的问题中“我不知道从哪里开始调试”这一部分，因为我相信从长远来看，这将是对你最有益的方法。

有两个最常见的事情需要调试，这也适用于您的用例：

通过检查Debug Services：

• 服务是否存在？
• 服务是否按DNS名称工作？
• 服务是否按IP工作？
• 是服务定义的代理吗?kube-
• 服务有任何代理工作吗？

<

• >F214>

Debug Running Pods解释了如何通过以下方式调试在节点上运行(或崩溃)的Pod：

使用具有短暂调试container

• Debugging的容器logs

• Debugging通过节点上的shell检查pod

我还推荐阅读Troubleshoot Applications指南：

本指南旨在帮助用户调试部署到Kubernetes中且运行不正常的应用程序。

步骤和详细信息可以在链接的源代码中找到。

了解上面的方法将帮助您从Kubernetes端了解在哪里以及首先要检查什么。我希望你会发现它很有用。
