I am considering running docker swarm(see the version below) or Kubernetes.

Is it possible to attach or set a static IP address to at service?

I am looking for a way to run multiple web sites in containers:

I understand that in Docker Swarm you can have Ingress network layer populating each nodes port 80. But that will only work for one IP address. What is I have more ip addresses that I would like to connect to different containers running different websites?
