Example Controller

A simple example of a Kubernetes controller written in Golang.

What it does is whenever a new Deployment is created in "default" namespace, it will expose the Deployment by creating a Service and an Ingress.

How to run?

go build -o bin/example-controller

bin/example-controller \
    --kubeconfig=$HOME/.kube/config \
    --workers 2 \
    --namespace default

Open another terminal and create a Deployment:

kubectl create -f ./example/deployment.yaml

Watch the logs of the controller.
