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.json
└── 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.json
:
{
"context": "k8s.prod.mydomain.com",
"include": [
{
"name": "some-api",
"values": {
"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.
