With the rise of microservices and IaaS, interest in container orchestration systems - like Kubernetes, Mesos, and Docker Swarm - has increased significantly. While many engineers will use these systems as a target to deploy their service to, they also expose an API that can be integrated in an application, allowing it to interact with it. In this talk, we will create a simple reverse proxy in Scala that can act as a Kubernetes Ingress Controller, similar to Traefik and linkerd. We are going to use some features from Kubernetes such as its event streams, ingresses, and services. This will provide a good opportunity to expose how an engineer can use the Kubernetes API to build systems needing to be both dynamic and responsive to what is happening on it.
