Writing a Kubernetes custom controller (ekspose) from scratch to expose your deployment | Part - 1

In this video I actually tried to write a Kubernetes custom controller (ekspose) that exposes your Kubernetes deployments automatically. When we say exposing an application, we actually mean creating a Kubernetes service and ingress resource, so that people from outside of the cluster can access the application.
In this video we were just able to create service resource, but in the subsequent videos we are going to look into how to create ingress resource for the same.

I am so sorry about the background noise, it became unacceptable between 35:54-43:29.
