Kubernetes is an open-source platform for scaling containerized workloads across a fleet of machines. It can intelligently schedule work only onto hosts that have the CPU and memory resources needed to run a given container. The challenge is that containers within a Kubernetes cluster typically communicate over a private overlay network. How should you expose services within the cluster to external clients? The answer is to bring the power of HAProxy to Kubernetes. The HAProxy Ingress Controller is the most efficient way to route traffic into a Kubernetes cluster.
