Is it possible to expose pods application of different ports on single IP on different port for example that
microservices-cart LoadBalancer 10.15.251.89 35.195.135.146 80:30721/TCP
microservices-comments LoadBalancer 10.15.249.230 35.187.190.124 80:32082/TCP
microservices-profile LoadBalancer 10.15.244.188 35.195.255.183 80:31032/TCP would look like
microservices-cart LoadBalancer 10.15.251.89 35.195.135.146 80:30721/TCP
microservices-comments LoadBalancer 10.15.249.230 35.195.135.146 81:32082/TCP
microservices-profile LoadBalancer 10.15.244.188 35.195.135.146 82:31032/TCP Reusing the same external IP is usually accomplished by using ingress resources.
See https://kubernetes.io/docs/concepts/services-networking/ingress/
But you'll have to route with paths instead of ports.
One possible solution is to combine NodePort and a reverse proxy. NodePort expose pods on different ports on all nodes. The reverse proxy serves as the entrance and redirects traffic to nodes.
One way or another you'll have to consolidate onto the same pod.
You can create a deployment that proxies each of the ports to the appropriate service. There are plenty of ways to create a TCP proxy - via nginx, node via package, there's a Go package maintained by Google; whatever you're most comfortable with.
