kube-custom-controller

This repository contains an example of how you can create a custom controller for custom resources in Kubernetes.

Whenever you create a custom resource of type Comment, it will publish a comment on an issue of this repository.

Go ahead, have fun! Play around with this demo and see your comment appear on Github. 😄

Installing

$ go get github.com/nikhita/kube-custom-controller/...
$ go build

Usage

Prerequisites:

• A Github API token
• A kubeconfig file

1. Make sure you export your kubeconfig file and Github API token as follows:

   $ export KUBECONFIG=path/to/kubeconfig-file
   $ export TOKEN=<github-api-token>
   

2. Then run the controller:

   $ ./kube-custom-controller
   

3. Create a CustomResourceDefinition to register the type Comment.

   $ kubectl create -f artifacts/crd.yaml
   

4. Create a custom object of type Comment. Don't forget to change the message in this file!

   $ kubectl create -f artifacts/cr.yaml
