Requirements

Minikube requires that VT-x/AMD-v virtualization is enabled in BIOS. To check that this is enabled on OSX / macOS run:

sysctl -a | grep machdep.cpu.features | grep VMX

If there's output, you're good!

kubectl multi-version brews

We need to run multiple versions of kubectl for compatibility with various kubernetes clusters.

It's a bit easier to get and use multiple versions of kubectl using Homebrew than it is using Macports.

With brew, it's simple to:

• Switch between them as needed
