The core objective of the Cloud Foundry community is to deliver the best developer experience we can offer. As Chip Childers has said, the success of open source communities lays in their ability to build bridges — so when Kubernetes became widely popular, the Cloud Foundry community started bringing the two technologies together for the benefit of users. The community is now fully aligned around the mission of bringing the Cloud Foundry developer experience to Kubernetes clusters.
As a result, the community has created multiple projects that enable developers to use Cloud Foundry with Kubernetes: Eirini, Project Quarks, and KubeCF.
This post will help you decide which of these projects best serves your use case for Cloud Foundry and Kubernetes.
Eirini began the community’s journey of pluggable components by offering Cloud Foundry users a choice between Diego (the native scheduler) or Kubernetes. Eirini’s goal is to ensure that users have the same experience regardless of the scheduler used.

Quarks (which includes “CF Operator”) packages CFAR as Docker images, enabling easy deployment to Kubernetes. The resulting containerized CFAR provides an identical developer experience as BOSH-managed Cloud Foundry installations and delivers a familiar operational experience to Kubernetes operators.

KubeCF is a distribution of CFAR for Kubernetes. It gives developers the productivity offered by Cloud Foundry combined with the ability for platform operators to manage the infrastructure abstraction with Kubernetes tools and APIs.

Quick Reference Guide
KubeCF combines Eirini and Quarks, and is the easiest way to get the benefits of both Eirini and Quarks.
When to use Eirini: To schedule user apps on Kubernetes.
When to use Quarks: To deploy and manage BOSH releases on Kubernetes.
When to use KubeCF: To distribute Cloud Foundry Application Runtime on top of Kubernetes.
We hope this is useful as you decide which Cloud Foundry project best serves your needs. If you are interested in learning more or would like to provide feedback to the teams, don’t hesitate to hop over to Cloud Foundry slack (#eirini-dev, #quarks-dev, and #kubecf-dev channels).
