Kubernetes, expose all ports
In Kubernetes, you will need service to communicate with pods. To expose the pods outside the Kubernetes cluster, you can use k8s service of NodePort type.
apiVersion: v1kind: Servicemetadata: name: my-servicespec: selector: app: MyApp type: NodePort ports: - port: 8080 nodePort: 30000 name: my-port-8080 - port: 8081 nodePort: 30001 name: my-port-8081 - port: 8082 nodePort: 30002 name: my-port-8081Then you will be able to reach your pods at, https://<node-ip>:nodePort.For in-cluster communication, you can use service's dns: <service-name>.<namespace>.svc:PORT
Update:
Take a look at this guide: Using a Service to Expose Your App
You are correct.
Pods are not "real" servers, their are rather application-instances with open ports.
Because of the docker- and kubernetes-network-implementation it's not possible to build what you want.
I don't know your use-case, but maybe you are not looking for kubernetes.
