Expose port 80 and 443 on Google Container Engine without load balancer

google-cloud-platformgoogle-compute-enginekubernetes

Currently I'm working on a small hobby project which I'll make open source once it's ready. This service is running on Google Container Engine.
I chose GCE to avoid configuration hassle, the costs are affordable and to learn new stuff.

My pods are running fine and I created a service with type LoadBalancer to expose the service on port 80 and 443. This works perfectly.

However, I discovered that for each LoadBalancer service, a new Google Compute Engine load balancer is created. This load balancer pretty expensive and really over done for a hobby project on a single instance.

To cut the costs I'm looking for a way to expose the ports without the load balancer.

What i've tried so far:

Is there a way to expose port 80 and 443 for a single instance on Google Container Engine without a load balancer?

Yep, through externalIPs on the service. Example service I've used:

apiVersion: v1
kind: Service
metadata:
  name: bind
  labels:
    app: bind
    version: 3.0.0
spec:
  ports:
    - port: 53
      protocol: UDP
  selector:
    app: bind
    version: 3.0.0
  externalIPs:
    - a.b.c.d
    - a.b.c.e

Please be aware that the IPs listed in the config file must be the internal IP on GCE.
