Ops engineers can use Kubernetes operators for their work!
I feel there's a gap, or fear from going into building a K8s controller so I made this video to support colleagues around the world.
An operator / controller can respond to live events on the cluster and perform various tasks, while maintaining high availability and best practices!
This video shows the use of "Kubebuilder" and how it can generate most of the Go code for you, leaving you to implement your logic inside.
I've chosen to implement a simple controller that responds to pod events, and reports to slack when they occur.
