Federation Dev

This repository contains demonstrations, labs, and examples of the use of Kubefed and/or the management of multiple OpenShift clusters.

What is Federation

Put quite simply, Federation is the process of connecting one or more Kubernetes clusters. The explanation from OperatorHub states Kubernetes Federation is a tool to sync (aka "federate") a set of Kubernetes objects from a "source" into a set of other clusters. Common use-cases include federating Namespaces across all of your clusters or rolling out an application across several geographically distributed clusters. The Kubernetes Federation Operator runs all of the components under the hood to quickly get up and running with this powerful concept. Federation is a key part of any Hybrid Cloud capability. There are two ways to use Kubefed currently: Namespace and Cluster scoped. For a breakdown of what this entails, see our KubeFed Cluster-Scoped Vs Namespace-Scoped guide.

Namespace Scoped labs

Namespace scoped Federation was initially the only supported mechanism for federating multiple OpenShift/Kubernetes environments. Namespace scoped Federation uses OperatorHub, which is included within OpenShift 4.1, to install the Federation Operator.

OpenShift 3.11 versions for the simple application scenario are also available:

Cluster Scoped

Cluster scoped KubeFed is now supported as of version 0.1.0 of the KubeFed operator.
