Question

I created a deployment file which runs some service. The service uses port 7777. I want to access the same service from the outside by typing the address xxxx:7777. I am attaching my deployment file which is currently working properly without service. If I download the Ports part from the Deployment and apply to the service, nothing works. I need to prepare a service file because I will soon connect more additional services that will each use the same IP address but on different ports. What is the best way to work in order to achieve my goal?

Answer 1

Update the service type as nodeport as below

apiVersion: v1
kind: Service
metadata:
  annotations:
    kompose.cmd: kompose convert -f docker-compose.yml
    kompose.version: 1.7.0 (HEAD)
  creationTimestamp: null
  labels:
    io.kompose.service: xyz
  name: xyz
spec:
  type: NodePort
  ports:
  - protocol: TCP
    name: tcp
    port: 7777
    nodePort: 30077
  - protocol: UDP
    name: udp
    port: 7777
  selector:
    io.kompose.service: xyz

You can then access the service at HOSTNAME:30077

Answer 2

But I also want to use port 7777 from the outside
