Gravity

Gravity packages Kubernetes clusters into portable, versioned images for consistent deployment across air-gapped and on-premises environments.

Gravity (built by Teleport) simplifies software delivery by treating entire Kubernetes clusters as single-file artifacts. It bundles your application, its dependencies, and the Kubernetes runtime into a cluster image that installs in minutes regardless of the underlying infrastructure. Operators use this to eliminate configuration drift in high-security sectors like finance and defense where internet access is restricted. The tool handles the heavy lifting of cluster lifecycle management: it automates updates and security patches across thousands of nodes to ensure production environments remain identical to staging.
