[Metricbeat] Module for OpenShift/OKD

sorantis commented 5 years ago

Summary

OpenShift is a popular enterprise distribution of Kubernetes. Recently RedHat announced that "Nearly 50% of the top Fortune 100 companies are using Red Hat OpenShift. Almost 30% of the top Fortune Global 500 companies use OpenShift".

While OpenShift product and Kubernetes project have a lot in common, there are some concepts that are different between the two systems. One such concept, specific to OpenShift is Multi-Project Quotas.

Definitions

OpenShift Projects are Kubernetes namespaces with additional annotations, which encapsulate a set of objects, accounts, policies and constraints.

Resource Quotas provide constraints that limit aggregate resource consumption per project. Resources managed by the ResourceQuota object can be found in the OpenShift documentation.

In OpenShift quotas can be shared across multiple projects, which means that an aggregate of resources used in each project is used to limit resources across all the selected projects. A multi-project quota is defined by a ClusterResourceQuota object in OpenShift.

The AppliedClusterResourceQuota resource can be used by each project's administrator to view the multi-project quota documents that are applied to his or her project.

These two objects only present in OpenShift and therefore won't be captured by the vanilla Metricbeat module for Kubernetes.

User Story

As an OpenShift administrator I want to be able to monitor multi-project quota metrics using Metricbeat so that I could see remaining and used resources for all projects as well as per project.

Having this Metricbeat module will complement the Kubernetes metricsets for both OpenShift Enterprise and OKD clusters.

Part of this issue should be about doing actual testing of our current deployment files on OpenShift + updating the docs if needed.
