swarm is not limited to working with nodeport. I think i was not able to express what i was saying correctly.

Swarm has an ingress mode that is "built-in". It works like the kuberenetes ingress (with currently the same limitation of source-ip mapping). Let me re-emphasize built-in.

Swarm also has a load balanced nodeport mapping (called host mode). That is also built-in.

In fact, what I'm trying to say is the opposite of what you are perceiving - swarm is not superior. It is actually similar to kuberenetes.

However, swarm has saner built-in defaults - both ingress and overlay networks (no more flannel vs calico vs weave incompatibility issues). Kubernetes has an escape hatch for defaults - kubeadm+kompose. I keep praying that kubeadm+kompose becomes the keras for kubernetes tensorflow. Lots of defaults that lets you get started quickly.
