**What this PR does / why we need it**: The sample-controller makes extensive use of various mechanisms available in the client-go library. For writing custom controllers/operators it will be helpful if there is precise description of how the client-go library works and how/where it interfaces with custom controller code. This patch adds documentation that sheds light on how (parts) of the client-go library work and its interaction-points with controller code. The documentation and the diagram comes from [1], (link included here for reference purpose). [1] https://medium.com/@cloudark/kubernetes-custom-controllers-b6c7d0668fdf Contributing the diagram and the writeup was recommended by by @sttts and @nikhita on https://github.com/kubernetes/sample-controller/issues/13 **Release note**: ```release-note NONE ``` |

Kubernetes
Kubernetes is an open source system for managing containerized applications across multiple hosts; providing basic mechanisms for deployment, maintenance, and scaling of applications.
Kubernetes builds upon a decade and a half of experience at Google running production workloads at scale using a system called Borg, combined with best-of-breed ideas and practices from the community.
Kubernetes is hosted by the Cloud Native Computing Foundation (CNCF). If you are a company that wants to help shape the evolution of technologies that are container-packaged, dynamically-scheduled and microservices-oriented, consider joining the CNCF. For details about who's involved and how Kubernetes plays a role, read the CNCF announcement.
To start using Kubernetes
See our documentation on kubernetes.io.
Try our interactive tutorial.
Take a free course on Scalable Microservices with Kubernetes.
To start developing Kubernetes
The community repository hosts all information about building Kubernetes from source, how to contribute code and documentation, who to contact about what, etc.
If you want to build Kubernetes right away there are two options:
You have a working Go environment.
$ go get -d k8s.io/kubernetes
$ cd $GOPATH/src/k8s.io/kubernetes
$ make
You have a working Docker environment.
$ git clone https://github.com/kubernetes/kubernetes
$ cd kubernetes
$ make quick-release
For the full story, head over to the developer's documentation.
Support
If you need support, start with the troubleshooting guide, and work your way through the process that we've outlined.
That said, if you have questions, reach out to us one way or another.
