Configuration Templates

Configuration templates can be used to render device configurations from context data. Templates are written in the Jinja2 language and can be associated with devices roles, platforms, and/or individual devices.

Context data is made available to devices and/or virtual machines based on their relationships to other objects in NetBox. For example, context data can be associated only with devices assigned to a particular site, or only to virtual machines in a certain cluster.

See the configuration rendering documentation for more information.

A numeric value which influences the order in which context data is merged. Contexts with a lower weight are merged before those with a higher weight.

Data File

Template code may optionally be sourced from a remote data file, which is synchronized from a remote data source. When designating a data file, there is no need to specify template code: It will be populated automatically from the data file.

Template Code

Environment Parameters
