Comparison with Docker Swarm
Explore the comparison between Kubernetes Ingress and Docker Swarm networking. Understand how Kubernetes offers a standardized Ingress API supporting third-party controllers, while Docker Swarm lacks a formal API, relying on independent solutions. This lesson helps you grasp key functional and architectural differences in dynamic routing and load balancing features to make informed choices.
We'll cover the following...
Similarities
Both Kubernetes and Docker Swarm have Ingress, and it might sound compelling to compare them and explore the differences. While that might seem like the right thing to do, there is a problem. Ingress works quite differently across the two.
Swarm Ingress networking is much more similar to Kubernetes Services. Both can 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 type of the Overlay network that publishes ports to the outside world.
Note: The truth is that Swarm does not have an equivalent to Kubernetes Ingress controllers. That is, if we do not include Docker Enterprise Edition in the mix.
The fact that a Kubernetes Ingress equivalent does not ship with Docker ...
