Swarm Ingress networking is much more similar to Kubernetes Services. Both can, and should, be used to expose ports to clients both inside and outside a cluster. If we compare the two products, we’ll discover that Kubernetes Services are similar to a combination of Docker Swarm’s Overlay and Ingress networking. The Overlay is used to provide communication between applications inside a cluster, and Swarm’s Ingress is a flavor of Overlay network that publishes ports to the outside world. The truth is that Swarm does not have an equivalent to Kubernetes Ingress Controllers. That is, if we do not include Docker Enterprise Edition to the mix.
