Introduction

After running an OpenShift or Kubernetes cluster for a little while you find that you need to create reports on specific data about the cluster itself. Reporting on things like Project owners, container images in use, and project quota are just some of the things you might be asked about. There are multiple ways to do this, such as writing your own application that queries the API, or creating a shell script that wraps a bunch of cli commands. For very complex reports, these tactics may be required. For simpler requests, there is another way, using the provided command line client such as “oc” or “kubectl” and a built-in feature which allows you to specify the output format for your query.
