Warewulf is a stateless, network-boot cluster provisioning system designed primarily for high-performance computing clusters.
It lets administrators define node images, profiles, and overlays on a central Warewulf server, then boot bare-metal or virtual cluster nodes over the network into a known operating system state. The software is built for environments where repeatable deployment, diskless operation, and centralized management of large groups of Linux nodes are important.
This is free and open source software.
Key Features
- Provisions stateless and diskless cluster nodes over the network.
- Uses OS images to provide the base operating system and kernel for cluster nodes.
- Applies overlays to customize provisioned images with static files and dynamic templates.
- Provides node profiles for applying shared configuration across groups of systems.
- Includes the wwctl command-line tool for managing nodes, profiles, images, overlays, and services.
- Can configure cluster services including DHCP, TFTP, NFS, SSH, hostfile, and TLS.
- Uses iPXE as the default network bootloader, with GRUB support available as a technical preview.
