如何讓Kubernetes服務使用本地主機在Web瀏覽器上打開我的django應用程式？

我一直試圖讓我的 kubernetes 通過我的本地主機在瀏覽器上啟動我的 Web 應用程式。當我嘗試打開本地主機時，它超時了，我嘗試使用 minikube service --url 并且這也不起作用。我的所有部署和服務 pod 都在運行。我也嘗試過埠轉發并將型別更改為 nodeport。我已經提供了我的yaml、docker和svc 代碼。

apiVersion: v1
kind: Service
metadata:
  name: mywebsite
spec:
  type: LoadBalancer
  selector:
    app: mywebsite
  ports:
  - protocol: TCP
    name: http
    port: 8743
    targetPort: 5000

          limits:
            memory: "2Gi"
            cpu: "500m"

uj5u.com熱心網友回復：

這是由于您的容器在埠8000 上運行

但是您的服務正在將流量轉發到5000

apiVersion: v1
kind: Service
metadata:
  name: mywebsite
spec:
  type: LoadBalancer
  selector:
    app: mywebsite
  ports:
  - protocol: TCP
    name: http
    port: 8743
    targetPort: **8000**

部署應該是

apiVersion: apps/v1
kind: Deployment
metadata:
  name: mywebsite
spec:
  selector:
    matchLabels:
      app: mywebsite
  template:
    metadata:
      labels:
        app: mywebsite
    spec:
      containers:
      - name: mywebsite
        image: mywebsite
        imagePullPolicy: Never
        ports:
        - containerPort: **8000**
        resources:
          requests:
            cpu: 100m
            memory: 250Mi
          limits:
            memory: "2Gi"
            cpu: "500m"

您需要更改TARGETPORT在SVC

和containerPort在部署

要不然

改變

EXPOSE 8000到5000并命令在5000上運行應用程式

CMD ["python", "manage.py", "runserver", "0.0.0.0:5000"]

別忘了在上述更改后再次 docker build 一次。
