kubectl apply 命令后，应用程序未在网页上查看

Question

我正在运行一个名为 RSPM 的应用程序。在 kubectl apply -f 之后成功创建了 pod。但是只有在我运行 kubectl exec -it pod-name /bin/bash 命令后，该应用程序才会显示在网页上。知道为什么会这样吗？特此列出 YAML 文件。

deployment.yaml

apiVersion: apps/v1 
kind: Deployment
metadata:
  name: rspm-db-deployment
spec:
  selector:
    matchLabels:
      app: rspm
  template:
    metadata:
      labels:
        app: rspm
    spec:
      containers:
      - env:
        - name: RSPM_LICENSE
          value: MY LICENSE
        image: rstudio/rstudio-package-manager:latest
        name: rstudio-package-manager
        ports:
        - containerPort: 4242
        volumeMounts:
        - name: test-config
          mountPath: /etc/rstudio-pm/
        resources: {}
        securityContext:
          privileged: true
      volumes:
      - name: test-config
        configMap:
          name: test-config
      restartPolicy: Always
status: {}

---
kind: Service
apiVersion: v1
metadata:
  name: rstudio-pm
spec:
  selector:
    app: rspm
  ports:
  - protocol: TCP
    port: 4242
    targetPort: 4242
    nodePort: 31040
  type: NodePort

这里是 config.yaml 文件

apiVersion: v1
kind: ConfigMap
metadata:
  name: test-config
  labels:
    app: rspm
data:
  rstudio-pm.gcfg: |
    [Server]
    Address = http://testserver.local
    RVersion = /usr/lib64/R
    [HTTP]
    Listen = :4242

任何帮助将不胜感激！ 谢谢！

部署清单文件格式不正确，您丢失了 - 在容器中，请尝试：

apiVersion: apps/v1 
kind: Deployment
metadata:
  name: rspm-db-deployment
spec:
  selector:
    matchLabels:
      app: rspm
  template:
    metadata:
      labels:
        app: rspm
    spec:
      containers:
      - image: rstudio/rstudio-package-manager:latest
        name: rstudio-package-manager
        ports:
        - containerPort: 4242
        volumeMounts:
        - name: test-config
          mountPath: /etc/rstudio-pm/
        resources: {}
        securityContext:
          privileged: true
      volumes:
      - name: test-config
        configMap:
          name: test-config
      restartPolicy: Always
status: {}

对我来说，pod 没有启动，我在 pod 中获取了这些日志：
