As we already have Homebrew installed from the previous chapter, we are going to use the brew command to install Kubeless. To do this, we need to add the Kubeless tap; a tap is a third-party repository that contains software installation instructions. Once the tap has been added, we can then install Kubeless in much the same way we did Minikube in Chapter 2, An Introduction to Kubernetes.
To install the tap and then install the Kubeless command-line client, run the following two commands:
$ brew tap kubeless/tap$ brew install kubeless
Once installed you can check the version of the client that was installed by running the following command:
$ kubeless version
