# Warewulf template variables
|
||||
|
||||
This Warewulf template serves as a complete example of the variables
|
||||
available to Warewulf templates. It may also be rendered against a
|
||||
node to debug its apparent configuration.
|
||||
|
||||
wwctl overlay show --render $nodename debug /warewulf/template-variables.md.ww
|
||||
|
||||
The template data structure is defined in
|
||||
internal/pkg/overlay/datastructure.go, though it also references
|
||||
data from other structures.
