I have individual kubernetes containers up and running. Can someone please help me how to link them? I have worked on docker compose and there it works like this:

redis:
    image: redis
    hostname: redis
    expose:
      - "6379"

  nginx:
    image: xxx.xx.xx.xx:5000/nginx:0.1
    expose:
      - "8080"
    ports:
      - "8080:8080"
    depends_on:
      - active-webserver
      - passive-webserver

  active-webserver:
    image: xxx.xx.xx.xx:5000/webserver:0.1
    hostname: active-webserver
    depends_on:
      - redis
    links:
      - redis
    expose:
      - "8081"
    ports:
      - "8090:8081"

  passive-webserver:
    image: xxx.xx.xx.xx:5000/webserver:0.1
    hostname: passive-webserver
    depends_on:
      - redis
      - kafka
    links:
      - redis
      - kafka
    expose:
      - "8081"
    ports:
      - "8091:8081"

But when coming to kubernetes, I have no clue how to proceed. I have service and deployment files created after using kompose but it actually broke the links between the code.

Service file:

apiVersion: v1
kind: Service
metadata:
  annotations:
    kompose.cmd: kompose convert -f docker-compose.yaml
    kompose.version: 1.5.0 (999278f)
  creationTimestamp: null
  labels:
    io.kompose.service: nginx
  name: nginx
spec:
  ports:
  - name: "8080"
    port: 8080
    targetPort: 8080
  selector:
    io.kompose.service: nginx
status:
  loadBalancer: {}

And my deployment file is:

apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  annotations:
    kompose.cmd: kompose convert -f docker-compose.yaml
    kompose.version: 1.5.0 (999278f)
  creationTimestamp: null
  labels:
    io.kompose.service: nginx
  name: nginx
spec:
  replicas: 1
  strategy: {}
  template:
    metadata:
      creationTimestamp: null
      labels:
        io.kompose.service: nginx
    spec:
      containers:
      - image: xxx.xx.xx.xx:5000/nginx:0.1
        name: nginx
        ports:
        - containerPort: 8080
        resources: {}
      restartPolicy: Always
status: {}
