Experimenting with k6 and Kubernetes

Prerequisite...you MUST have a running installation of Docker!

For this experiment, we will:

install a local Kubernetes cluster running in Docker
optionally install some tooling to give us visibility into the cluster
build a custom k6 binary having xk6-kubernetes
run some simple scripts to test our local cluster

Build and run `k6` with `xk6` extensions using Docker

Not everyone loves the Go programming language as myself...I get that. If you're just looking to be able to use k6 OSS with some available extensions and don't want to mess with setting up a Go(lang) environment, then this gist is for you!

🎅 What will this do for me?

This will provide a couple resources to make it simple to create your own customized version of k6 and execute tests all within Docker.

It should come as no surprise that you will need Docker installed!

💁 Why do I want this?

Introduction to Kafka

Kafka acts as a kind of write-ahead log (WAL) that records messages to a persistent store (disk) and allows subscribers to read and apply these changes to their own stores in a system appropriate time-frame.

Terminology:

Producers send messages to brokers
Consumers read messages from brokers
Messages are sent to a topic
