kind-terraform-yaks's Introduction

Lab with Kind, Terraform and YAKS

This is a lab experiment that creates a Kind Kubernetes cluster, installs a YAKS Operator using Terraform and run a sample test.

Tools

  • Terraform v. 1.4.5
  • Kubectl v. 1.27.1
  • Yaks v. 0.16.0
  • Git v. 2.34.1

Step by step

  1. Install all tools
  2. Using an IDE such as VS Code or even any terminal, clone locally this repository with Git
  3. Run terraform apply -auto-approve will create all resources (this may take ~ 5 min)
  4. Run a test with command yaks run apps/yaks/helloworld.feature
  5. Show tests results with kubectl get tests
