Navigating the Sea of Local Kubernetes Clusters

Your company has decided to migrate to Kubernetes. Exciting! Time to set up your development environment so you can quickly test your application changes in a real cluster. But, what should your development environment look like? Should you use minikube? kind? Something completely different?

In this demo-led session we’ll have a look at some of the tools that help you locally deploy your Kubernetes application as part of your development process. We’ll show the differences between each tool from a technical and UX point of view, so you can choose the ones that better fit your use case.
