How to upgrade minikube?

Question

Before reinstall minikube (OS X), check the following:

Make sure that you have brew updated:
```
brew update
```
Make sure that you already have cask installed:
```
brew cask install minikube --verbose
```

Finally, execute the following command in the same directory you’ve installed minikube previously (usually /usr/local/bin/):

brew cask reinstall minikube

If you see an output similar to this:

Error: It seems there is already a Binary at '/usr/local/bin/minikube'; not linking.

Now, you should able to reinstall (upgrade) minikube. 🙂
