Running Apache OpenWhisk locally

We are going to be looking at running Apache OpenWhisk locally first. We will do this by using a combination of VirtualBox, which we installed in Chapter 3, Installing Kubernetes Locally, and Vagrant.

Installing Vagrant

Before we launch our local Apache OpenWhisk server we need to install Vagrant, which is developed by HashiCorp. The best way I can describe Vagrant is as an open source, virtual machine manager, where your machine configuration is written using an easy-to-follow text configuration file.

Installing Vagrant is quite simple. On macOS 10.13 High Sierra we can use Homebrew and Cask:

$ brew cask install vagrant

If you are running Windows 10 Professional you can use Chocolatey and run the following:

$ choco install vagrant

Finally, if you are running Ubuntu 17.04 you can install Vagrant directly from the core Ubuntu repositories by running:

$ sudo apt-get update
$ sudo apt-get install vagrant

Please note, the version supplied by Ubuntu may be a little behind...
