j2render

j2render is a linux cli tool that interpolates jinja2 templates and variables in a declarative way.

For each file/template that you want to render, you need to define a config.yaml file with the following syntax:

resources:
  - name: yamlResource1
    template: some.template
    output_file: /tmp/rendered1.config
    variables:
      key1: value1
      key2: value2
      key3: value3

In the example above, j2render will read a template file called some.template and will try to interpolate the key1, key2, key3 variables, creating an output file on /tmp/rendered1.config.

The template should use two curly braces to be able to receive the value as it will be rendered using jinja2.render:

items:
  - key1: "{{ key1 }}"
  - key2: "{{ key2 }}"
  - key3: "{{ key3 }}"
