🐵 Performance Testing and Chaos Engineering Workshop 💣

Just so you know, we're only supporting Mac lappys running a recent-ish macOS.

If you run into problems, check out the Hello Minikube walkthrough and Microservices demo on Kubernetes setup instructions.

To start off

First you need to install the software and run the demo.

• Read the makefiles, and then run make setup . It will install the following:
  • Homebrew, if you don't have it.
  • VirtualBox, a virtual machine handler.
  • kubectl, which we use to control Kubernetes instances.
  • Minikube, a small-scale Kubernetes instance.
    • Plus a hypervisor driver that Minikube uses.
• Run make start to fire up Minikube. It'll take a few mins to get going.
  • Now, make show-dashboard will show you to the Kubernetes dashboard for your Minikube instance.
• Run make get-demo to pull down the microservices-demo codebase.
• Run make deploy-demo to make Kubernetes deploy it to your Minikube instance.
• Run make show-demo-pods, Kubernetes will show you the deployment status of your pods.
  • Wait until they are all running.
• Run make show-demo-frontend
  • Now you can buy socks!

Load testing

With the microservices demo running, we can run some load testing tools against it.

Gatling

• Run make get-gatling to pull down the Gatling Docker container.
• Run make run-gatling to run Gatling. It will run load tests against the microservices-demo frontend.
• Run make show-gatling-reports to show test reports.
• Look at ./gatling/user-files/simulations/Simulation.scala to see the test script (Scala) and make changes to it.

Locust

• Run make get-locust to pull down a modified version of the Locust Docker container.
• Run make run-locust to run Locust. It will run load tests against the microservices-demo frontend.
• Look at ./locust/locustfile.py to see the test script (Python) and make changes to it.

Chaos Engineering

To be explained during the session.

If something goes wrong

• Run make delete to delete the Minikube instance.

If you still have problems,

• Run make destroy to remove all Minikube files.
