The record

Purpose: Warewulf provisions and manages stateless Linux clusters, most prominently for high-performance computing.
Scale: The project describes deployments ranging from tens to tens of thousands of compute systems.
Node images: Warewulf v4 manages bootable operating system images with container tooling or CI/CD pipelines, including DockerHub and private GitLab CI infrastructure.
Management: Its server provides the wwctl command-line interface for managing nodes, images, and overlays, with YAML node definitions and reusable profiles.
Provisioning: Warewulf supports iPXE network booting and template-based overlays applied at boot or runtime.
Hardware and Linux support: The documentation says Warewulf is distribution and hardware agnostic, citing ARM and x86 plus Debian, SUSE, Rocky, CentOS, and RHEL.
Additional use cases: The project says Warewulf can also serve clustered web servers, rendering farms, Kubernetes deployments, and cloud deployments.
Integrations: The project identifies container tooling, CI/CD pipelines, OpenHPC, Ansible, and Slurm among the tools and ecosystems it works with or aims to integrate with.
Security: Warewulf supports SELinux and offers asset-key checks, secure mode, optional TLS for runtime overlays, and Secure Boot with shim and GRUB.
Security limitation: By default, provisioning requests can be spoofed to download OS images and overlays, and the kernel and system image remain unencrypted even when TLS is enabled.
Feature maturity: The documentation marks GRUB, Secure Boot, disk provisioning, provision-to-disk, and dnsmasq as preview features, and generic resources as incomplete.
Support: Warewulf offers free documentation, Slack, and GitHub community resources, while commercial support is available through CIQ and SUSE.
Installation: The project documents RPM packages for Rocky Linux 9 and openSUSE Leap, plus source builds and Linux container builds.
API: Warewulf includes a REST API that is disabled by default and can be configured to require TLS.
