Zarf - DevSecOps for Air Gap

Zarf eliminates the complexity of air gap software delivery for Kubernetes clusters and cloud-native workloads using a declarative packaging strategy to support DevSecOps in offline and semi-connected environments.

Why Use Zarf

• 💸 Free and Open-Source. Zarf will always be free to use and maintained by the open-source community.
• ⭐️ Zero Dependencies. As a statically compiled binary, the Zarf CLI has zero dependencies to run on any machine.
• 🔓 No Vendor Lock. There is no proprietary software that locks you into using Zarf. If you want to remove it, you still can use your helm charts to deploy your software manually.
• 💻 OS Agnostic. Zarf supports numerous operating systems. A full matrix of supported OSes, architectures and featuresets is coming soon.
• 📦 Highly Distributable. Integrate and deploy software from multiple secure development environments including edge, embedded systems, secure cloud, data centers, and even local environments.
• 🚀 Develop Connected, Deploy Disconnected. Teams can build and configure individual applications or entire DevSecOps environments while connected to the internet. Once created, they can be packaged and shipped to a disconnected environment to be deployed.
• 💿 Single File Deployments. Zarf allows you to package the parts of the internet your app needs into a single compressed file to be installed without connectivity.
• ♻️ Declarative Deployments. Zarf packages define the precise state for your application enabling it to be deployed the same way every time.
• 🦖 Inherit Legacy Code. Zarf packages can wrap legacy code and projects - allowing them to be deployed to modern DevSecOps environments.

Special Thanks

Early Zarf research and prototypes were developed jointly with United States Naval Postgraduate School research you can read here.

We would also like to thank the following awesome libraries and projects without which Zarf would not be possible!
