我已经部署了一个 Drupal 实例，但我看到实例端点不可见，尽管容器部署成功

Question

我已经部署了一个 Drupal 实例，但我发现尽管容器部署成功，但实例端点不可见。

容器日志不指向任何方向

任何指示都非常有用。

注意：当运行容器使用命令

时，这非常有效

docker run --name some-drupal -p 8080:80 -d drupal

您的服务选择器有两个值：

Selector:                 app=drupal,type=frontend

但是您的 pod 只有其中之一：

spec:
  template:
    metadata:
      labels:
        app: drupal

只需确保服务所需的所有标签确实存在于 pod 上即可。

喜欢以下内容：

apiVersion: apps/v1
kind: Deployment
metadata:
  name: drupal-deployment
spec:
  replicas: 1
  selector:
    matchLabels:
      app: drupal
      type: frontend
  template:
    metadata:
      labels:
        app: drupal
        type: frontend   #     <--------- look here
    spec:
      containers:
      - name: drupal
        image: drupal
        resources:
          limits:
            memory: "128Mi"
            cpu: "500m"
        ports:
        - containerPort: 80

我已经部署了一个 Drupal 实例，但我看到实例端点不可见，尽管容器部署成功

I have deployed a Drupal Instance but i see that the instance Endpoint are not visible although the containers deployed successfully
