Running Apache Kafka On Kubernetes

Rohit Bakhshi walks us through how to install Kafka on a Kubernetes cluster:

Now available on GitHub in developer preview are open-source Helm Chart deployment templates for Confluent Platform components. These templates enable developers to quickly provision Apache Kafka, Apache ZooKeeper, Confluent Schema Registry, Confluent REST Proxy, and Kafka Connect on Kubernetes, using official Confluent Platform Docker images.

Helm is an open-source packaging tool that helps you install applications and services on Kubernetes. Helm uses a packaging format called charts. A chart is a collection of YAML templates that describe a related set of Kubernetes resources.

For stateful components like Kafka and ZooKeeper, the Helm Charts use both StatefulSets to provide an identity to each pod in the form of an ordinal index, and Persistent Volumes that are always mounted for the pod. For stateless components, like REST Proxy, the Helm Charts utilize Deployments instead to provide an identity to each pod. Each component’s charts utilize Services to provide access to each pod.
