K8s Airgap Buddy

Zarf - Kubernetes Air Gap Buddy

Zarf massively simplifies the setup & administration of kubernetes clusters "across the air gap".

It provides a static go binary CLI that can pull, package, and install all the things your clusters need to run. It caches downloads (for speed), hashes packages (for security), and can even install the kubernetes cluster itself if you want it to.

Zarf runs on a bunch of operating systems and aims to support configurations ranging from "I want to run one, simple app" to "I need to support & dependency control a bunch of internet-disconnected clusters".

 

This repo is in transition from Repo1 by DoD Platform One to Github. See the announcments post for the latest URLs for this project during this transition.

 

 

If you're just getting into Zarf, you should...

Get Started Using Zarf	Experience just how easy it is to go from zero to chainsaw wielding hero (of the Kubernetes cluster) using Zarf!	Read
Add Logging Zarf components	Sometimes running your app in-cluster is enough—usually, it's not. Find out how to inject commonly-required, uber-useful functionality through the use of Zarf components.	Read
Roll Your Own Custom packages	Once you're comfortable with the basic workflow & able to deploy someone else's Zarf deployment packages, it's time to roll your own. Here's how.	Coming Soon!

 

To understand the different modes of use, have a look at...

Simple Applications Appliance Mode	If want to "run a Kubernetes app" but aren't into hand-rolling a cluster just for it, Zarf can help. Here's how, and why you might want to.	Coming Soon!
Disconnected GitOps The Utility Cluster	Zarf overcomes the "the Air Gap problem" using a Kubernetes cluster (and k8s-native tooling) for the care & feeding of other k8s clusters. Here's how it works and what ops/support looks like.	Coming Soon!
