KonTemplate - A simple Kubernetes templater

I made this tool out of frustration with the available ways to template Kubernetes resource files. All I want out of such a tool is a way to specify lots of resources with placeholders that get filled in with specific values, based on which context (i.e. k8s cluster) is specified.

Overview

KonTemplate lets you describe resources as you normally would in a simple folder structure:

.
├── prod-cluster.yaml
└── some-api
    ├── deployment.yaml
    └── service.yaml

This example has all resources belonging to some-api (no file naming conventions enforced at all!) in the some-api folder and the configuration for the cluster prod-cluster in the corresponding file.

Lets take a short look at prod-cluster.yaml:

---
context: k8s.prod.mydomain.com
global:
  globalVar: lizards
include:
  - name: some-api
    values:
      version: 1.0-0e6884d
      importantFeature: true
      apiPort: 4567

Those values are then templated into the resource files of some-api.

Usage

You must have kubectl installed to use KonTemplate.
