We can configure this dependency in a docker-compose.yml file, which will ensure that the Zookeeper server always starts before the Kafka server and stops after it. Let's create a simple docker-compose.yml file with two services — namely, zookeeper and kafka: Getting Started with Landoop’s Kafka on Docker for Windows. Here’s a quick guide to running Kafka on Windows with Docker. I’ll show you how to pull Landoop’s Kafka image from Docker Hub, run it, and how you can get started with Kafka. We’ll also be building a .NET Core C# console app for this demonstration.

A normal start-up sequence for a Kafka server is like this: A: start Zookeeper server B: start Broker server C: create topic. Item A and B are long running process.
