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.

• 💸 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.

• Automate Kubernetes deployments in disconnected environments
• Automate Software Bill of Materials (SBOM) generation
• Build and publish packages as OCI image artifacts
• Provide a web dashboard for viewing SBOM output
• Create and verify package signatures with cosign
• Publish, pull, and deploy packages from an OCI registry
• Powerful component lifecycle actions
• Deploy a new cluster while fully disconnected with K3s or into any existing cluster using a kube config
• Builtin logging stack with Loki
• Builtin Git server with Gitea
• Builtin Docker registry
• Builtin K9s Dashboard for managing a cluster from the terminal
• Mutating Webhook to automatically update Kubernetes pod's image path and pull secrets as well as Flux Git Repository URLs and secret references
• Builtin command to find images and resources from a Helm chart
• Tunneling capability to connect to Kubernetes resources without network routing, DNS, TLS or Ingress configuration required

• Customizable variables and package templates with defaults and user prompting
• Composable packages to include multiple sub-packages/components
• Component-level OS/architecture filtering

To try Zarf out for yourself, visit the "Try It Now" section on our website, and if you want to learn more about Zarf and its use cases visit docs.zarf.dev.

From the docs you can learn more about installation, using the CLI, making packages, and the Zarf package schema.

Using Zarf in Github workflows? Check out the setup-zarf action. Install any version of Zarf and its init package with zero added dependencies.

To contribute, please see our Contributor Guide. Below is an architectural diagram showing the basics of how Zarf functions which you can read more about here.

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!
