Build Status Maintainability

A simple template reader and variable injector

  • Used for when you have a bunch of templates (e.g. kubernetes files) and want to inject a yaml file of variables
  • Supports giving it a directory of nested templates and an output path (it will reproduce the directory structure)

Example

demo.tmpl

apiVersion: v1
kind: Pod
metadata:
  name: console
spec:
  restartPolicy: Always
  containers:
    - name: {{.name}}
      image: {{.image}}

vars.yaml

name: "test"
image: "us.gcr.io/test"

The result;

apiVersion: v1
kind: Pod
metadata:
  name: console
spec:
  restartPolicy: Always
  containers:
    - name: test
      image: us.gcr.io/test

Usage

vortex -template example/demo.tmpl -output test.txt -varpath example/vars.yaml

Recursive folder templating

Vortex also can recursively follow a template folder

e.g.

somefolders/
            foo/
                template.yaml
            bar/
                another.yaml


vortex -template somefolders -output anoutputfolder -var example/vars.yaml
