sample-controller

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

It makes use of the generators in k8s.io/code-generator to generate a typed client, informers, listers and deep-copy functions. You can do this yourself using the ./hack/update-codegen.sh script.

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

  • pkg/apis/samplecontroller/v1alpha1/zz_generated.deepcopy.go
  • pkg/client/

Changes should not be made to these files manually, and when creating your own controller based off of this implementation you should not copy these files and instead run the update-codegen script to generate your own.

Purpose

This is an example of how to build a kube-like controller with a single type.

Compatibility

HEAD of this repository will match HEAD of k8s.io/apimachinery and k8s.io/client-go.

Where does it come from?

sample-controller is synced from https://github.com/kubernetes/kubernetes/blob/master/staging/src/k8s.io/sample-controller. Code changes are made in that location, merged into k8s.io/kubernetes and later synced here.
