# cloud-controller-manager/example

This directory provides an example of how to leverage CCM extension mechanism.

## Purpose

Begin with 1.20, all cloud providers should not copy over or vendor in `k8s.io/kubernetes/cmd/cloud-controller-manager`. Inside this directory, an example is included to demonstrate how to leverage CCM extension mechanism to add a controller.

### Install Google Cloud SDK

If you haven't already installed the Google Cloud SDK, follow the instructions [here](https://cloud.google.com/sdk/). If you're not
sure if you have it installed, you can check with:

```bash
which gcloud
```

### Create a project

```shell
$ gcloud compute images list --project=cos-cloud | grep cos-cloud
cos-69-10895-385-0                                    cos-cloud          cos-69-lts                                    READY
