frontend deployment.yml

Here, I'm using the backend API address as kubernetes.docker.internal but I don't know if it's true or not. I want to use my Django API and what address should I write here and also in React how to use it,

currently, I'm using like this

fetch(`${process.env.REACT_APP_API_URL}/api/movies/

I think I need to add port also,in above line

apiVersion: apps/v1
kind: Deployment
metadata:
  name: movie-frontend
spec:
  replicas: 1
  selector:
    matchLabels:
      app: movie-frontend
  template:
    metadata:
      labels:
        app: movie-frontend
    spec:
      containers:
        - name: movie-frontend
          image: javiercode/movie-frontend
          env:
            - name: REACT_APP_API_URL
              value: "kubernetes.docker.internal"

frontend service

apiVersion: v1
kind: Service
metadata:
  name: movie-frontend-service
spec:
  selector:
    app: movie-frontend
  ports:
    - protocol: TCP
      port: 3000
      targetPort: 3000
  type: LoadBalancer

frontend docker file

FROM node 

WORKDIR /app

COPY package.json .
