Rendro - A Jinja template rendering CLI tool written in Rust

Description

• Rendro is a CLI tool designed to take Jinja templates (*.j2 files by default) and render them using environment variables. Any templates with the file extension .j2 will have the extension stripped (i.e. my_template.yaml.j2 -> my_template.yaml), otherwise the filename will be left as-is.

EXAMPLE:

apiVersion: v1
kind: ConfigMap
metadata:
  name: test-configmap
data:

  HOMEPATH: {{ env.homepath }}

Would, assuming an environment variable of HOMEPATH is set, become:

apiVersion: v1
kind: ConfigMap
metadata:
  name: test-configmap
data:

  HOMEPATH: YOUR_HOMEPATH_VAR_HERE

Usage

rendro render

• Using Rendro with no arguments will default to any .j2 file found in the ./src/templates directory being rendered and stored in the ./src/templates/temp directory

rendro render -i ./my-templates -o ./my-rendered-templates -x yaml

• This example will find any .yaml file in ./my-templates, render them, and store the rendered templates in ./my-rendered-templates
