1.2. Operating System
The LOCKSS system requires a 64-bit Linux host (physical or virtual) compatible with K3s, a lightweight Kubernetes distribution by Rancher. The K3s documentation states [1] that "K3s is expected to work on most modern Linux systems", and that "Some OSs have specific requirements" (which are documented in this manual and integrated into the lockss-installer scripts).
The LOCKSS team has successfully tested the LOCKSS system installation process on many flavors of Linux, some of which are listed below:
