The Charmed Apache Kafka Operator delivers automated operations management from Day 0 to Day 2 on the Apache Kafka event streaming platform. It is an open source, end-to-end, production-ready data platform on top of Juju. As a first step this tutorial shows you how to get Charmed Apache Kafka up and running, but the tutorial does not stop there. As currently Apache Kafka requires a paired Apache ZooKeeper deployment in production, this operator makes use of the Charmed Apache ZooKeeper Operator for various essential functions. Through this tutorial, you will learn a variety of operations, everything from adding replicas to advanced operations such as enabling Transport Layer Security (TLS).

In this tutorial, we will walk through how to:

Set up your environment using LXD and Juju.
Deploy Charmed Apache Kafka using a couple of commands.
Get the admin credentials directly.
Add high availability with replication.
Change the admin password.
Automatically create Apache Kafka users via Juju relations.

Basic terminal commands.
Apache Kafka concepts such as replication and users.
