Apache OpenWhisk and Kubernetes

In this chapter, we are going to look at Apache OpenWhisk. While not strictly a Kubernetes-only project, like, say, Kubeless and Fission (which are covered in the next chapter), it can be deployed on, and take advantage of, Kubernetes.

We are going to be looking at three main topics:

• An overview of Apache OpenWhisk
• Running Apache OpenWhisk locally using Vagrant
• Running Apache OpenWhisk on Kubernetes

Let's start by finding out more about OpenWhisk.
