Introduction
This step-by-step guide shows how to install Apache Kafka within a Ubuntu docker image. The reason why we choose a docker image here is so that we have a clean environment to work with.
Install Docker
To begin with, make sure you have Docker installed properly on your machine:
$ docker --versionDocker version 18.09.2, build 6247962
If you don’t have Docker installed, you download & install it from https://docs.docker.com/.
Ubuntu Container
Ubuntu docker image is available at the Docker Hub https://hub.docker.com/_/ubuntu. We’ll use the current latest version for this tutorial, which is 18.04. The following command docker run -it allows us to launch the docker image in the interactive foreground mode.
$ docker run -it ubuntu:18.04 bashUnable to find image 'ubuntu:latest' locally

We’ll do the rest of this tutorial inside this container.
