I wanted a simple CLI for Jinja2 that operated similarly to Helm:
This CLI aims to provide these features in the simplest way possible.
❯ j2 --help
a minimalist Jinja2 CLI
usage: j2 [-h] [--values [value.yaml]] [--set my.value=42]
template
positional arguments:
template Template file to process
optional arguments:
-h, --help show this help message and exit
--values [value.yaml]
Input values file path; "-" to use stdin
--filters [filters.py]
Custom Jinja2 filters from Python file. Loads all
top-level functions and registers them as filters.
--set my.value=42 Set values on the command line. Can be used multiple
times.
The j2 CLI is available as a Docker image hosted on Docker Hub:
https://hub.docker.com/r/thecodesmith/j2.
Basic usage:
j2 manifest.j2 --values values.yaml > manifest.yaml
With custom values overridden on the command line:
j2 manifest.j2 --values values.yaml --set app.namespace=foo > manifest.yaml
With custom filters defined in a file:
j2 manifest.j2 --filters filters.py > manifest.yaml
Where the filters file looks like this:
def parentheses(value):
""" Usage: {{ var | parentheses }} """
return '(' + value + ')'
