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 can still use your Helm charts to deploy your software manually.
💻 OS Agnostic. Zarf supports numerous operating systems. A full matrix of supported OSes, architectures, and feature sets 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.

📦 Out of the Box Features

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
Built-in Git server with Gitea
Built-in 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

🛠️ Configurable Features

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