= PodSet Operator

An example of Kubernetes Operator built with the https://github.com/operator-framework/operator-sdk[Operator SDK].

This PodSet operator takes care of scaling up and down pods that run a `sleep 3600` command in a busybox image. Nothing really fancy, but the point is to:

- see how the CRD and operator controller can be defined, packaged and deployed 
- demonstrate the logic of reconcialation when a custom resource changes, or when pods are added or removed by a user

Also, this operator has a `cluster` scope, which means that its controller can run in a single namespace, yet monitor changes of CR in all other namespaces.
