Writing Validating Webhook Controller From Scratch - 1 | Validating Webhook Kubernetes

In this video we wrote the https server that would work as validating webhook controller and deployed it on Kubernetes cluster to make sure that the server is being called/requested when a Kluster resource is created.
We also looked into how we can give the .crt and .key files to the server as flags that would be mounted on the application as secrets.
