About

This repository implements a simple controller for watching server resources as defined with a CustomResourceDefinition (CRD).

Code Generation

The update-codegen script will automatically generate the following files & directories:

• pkg/apis/hmsayem.com/v1/zz_generated.deepcopy.go
• pkg/client/

Fetch server-controller and its dependencies

git clone https://github.com/hmsayem/server-controller.git
cd server-controller

How to Run

Prerequisite: Since the sample-controller uses apps/v1 deployments, the Kubernetes cluster version should be greater than 1.9.

# assumes you have a working kubeconfig, not required if operating in-cluster
go build -o server-controller .
./server-controller -kubeconfig=$HOME/.kube/config

# create a CustomResourceDefinition
kubectl create -f artifacts/crd.yaml

# create a custom resource of type Foo
kubectl create -f artifacts/server.yaml

# check deployments created through the custom resource
kubectl get deployments
