			== Troubleshooting ==

			=== No network gateway ===
			There doesn't seem to be a way to define gateways in warewulf's managed dhcp.

			Edit <code>/etc/warewful/warewulf.conf</code> and set the dhcp template to 'static', then <code>wwctl overlay edit host etc/dhcpd.conf.ww</code> and add the following within the host definition.

Warewulf is an open-source Linux cluster provisioning system. It is typically used for HPC cluster applications, but can also be used for managing environments that need to boot multiple nodes (such as a VM infrastructure environment). Warewulf provides a lightweight and flexible way to boot diskless nodes via PXE and manage node images centrally from a head node.

== Common Commands ==

{|class="wikitable"
! Purpose
! Command
|-
| Check Warewulf node status
| {{code|wwcctl node status}}
|-
| View node details
| {{code|wwcctl node show <nodename>}}
|-

| Create a new node
| {{code|wwcctl node add <nodename> --ipaddr <ip> --hwaddr <mac>}}
|-

| Set boot image for a node
| {{code|wwcctl node set <nodename> --vnfs <image>}}
|-

| Build VNFS (node image)
| {{code|wwcctl overlay build}}
|-

| Import container image
| {{code|wwcctl import docker://rockylinux:9 --name rocky9}}
|-
| Push configuration to nodes
| {{code|wwcctl overlay build}}
|}

== Common Tasks ==

===Install and Configure Warewulf===

{{highlight|lang=terminal|code=
# wget https://github.com/warewulf/warewulf/releases/download/v4.6.4/warewulf-4.6.4-1.el9.x86_64.rpm
# dnf -y install warewulf-4.6.4-1.el9.x86_64.rpm

## Configure warewulf in /etc/warewulf/warewulf.conf
## Ensure that the IP addresses are set to something that works for your network.
# vi /etc/warewulf/warewulf.conf

## Set up the first boot image and configure the first node
# wwctl image import docker://ghcr.io/warewulf/warewulf-rockylinux:9 rockylinux-9 --build
# systemctl enable --now warewulfd
# wwctl profile set default --image rockylinux-9
# wwctl node add node01 --ipaddr=172.19.0.101 --hwaddr=02:01:01:58:00:06
# wwctl configure --all
}}

At this point, you should have a DHCP and TFTP running on the system. NFS server should also be working if that is something you enabled in the configuration file.

Verify the state of warewulf by running:
{{highlight|lang=terminal|code=
# warewulf status
}}
