FAQs

What is Warewulf Pro?

Warewulf Pro is a CIQ product based on the open-source Warewulf cluster provisioning system. It bundles Warewulf with a web interface, pre-built node images for common HPC stacks, supplementary configuration overlays, bundled Apptainer, and access to professional support.

What do I get when I buy Warewulf Pro?

• The Warewulf server, distributed through CIQ Depot, potentially with bugfixes ahead of upstream releases.
• The Warewulf Pro web interface (a Cockpit-based UI for cluster management).
• Pre-built compute node images for OpenHPC, Slurm, OpenPBS, and Fuzzball Substrate (multi-arch).
• Pro configuration overlays: apptainer, chrony, slurm, openpbs, fuzzball-substrate.
• CIQ-packaged Apptainer.
• Professional support with SLAs from CIQ.

How is Warewulf Pro different from community Warewulf?

The Warewulf server is the same code, distributed differently. Community users build or install from GitHub releases; Pro customers install from CIQ Depot, possibly with backported bugfixes ahead of upstream.

What's only in Pro: the web interface, the pre-built scheduler images, the Pro overlays, the bundled Apptainer, and professional support.

For the full comparison, see the overview page.

Can I use Warewulf Pro without the web interface?

Yes. The web interface is an optional component (warewulf-cockpit). The Warewulf server, wwctl CLI, Pro overlays, Apptainer, and node images all work without it.

Can I use the Pro overlays and node images with community Warewulf?

The overlays and node images are designed and tested for the Warewulf version that ships with Pro, but they're standard Warewulf overlays and OCI images - they will generally work with a community Warewulf install of a compatible version. They are not supported in that configuration.

How does Warewulf Pro versioning relate to upstream Warewulf?

Warewulf Pro follows semantic versioning. Upstream Warewulf uses an EPIC.MAJOR.MINOR scheme. See the Release notes page for the full mapping.

How do I install Warewulf Pro?

See Getting started. The short version:

# depot enable warewulf-pro
# dnf install warewulf warewulf-cockpit apptainer cockpit "warewulf-overlays-*"
# systemctl enable --now warewulfd cockpit.socket

Can I install Warewulf Pro on an air-gapped server?

Yes. Mirror the Depot repository to a connected host, then point your air-gapped server at the local mirror. See Air-gapped install.

Does Warewulf Pro run on ARM64?

Yes. Starting with Pro v1.1.1, the Warewulf server is built for aarch64. Starting with Pro v1.2.0, the Pro node images are also built for aarch64. See Pro node images: Multi-architecture support.

Can my Warewulf Pro nodes run Rocky Linux from CIQ (RLC) instead of community Rocky Linux?

Yes, if you also have an RLC entitlement. CIQ ships RLC-based variants of every Pro node image. See Pro node images: RLC variants.

Where do I report bugs or request support?

If you have a support contract, file a case through the CIQ Portal. For pre-sales questions, contact CIQ Sales.

For community Warewulf questions that aren't Pro-specific, the upstream Warewulf project maintains a community Slack and GitHub repository.
