About this Doc
Although the official repository is very helpful to understand a Kubernetes controller, it is still quite hard to read the source codes and implement it by yourself, especially for a newbie. So, I broke down the complete codes into steps in this repository (nakamasato/sample-controller) so anybody can create the example controller step by step from scratch.
I hope this documentation will be helpful to open the door to the world of Kubernetes operator.
