Golden Configuration (IOS) - Jinja2 Templates

Before we start building the lab exercise, we’re going to take a look at Jinja2 Templates. For those less familiar, Jinja2 is a templating language developed for Python that allows users to take structured data and format it for human readability. Here we’ll build a simple template that will show you how this is done. Part of today’s workflow will leverage a Jinja2 Template in order to format text for ServiceNow, so this small exercise will give you a better idea of how that workflow operates.

{% if vendorNames | length == 1 %}
The most common networking vendor I work with is {{ vendorNames[0] | title }}.

The most common networking vendors I work with are:
{% for vendor in vendorNames %}
 - {{ vendor | title }}
{% endfor %}
{% endif %}
