Problem this snippet solves:

This code offers a couple of examples of deploying NGINX App Protect on Kubernetes Ingress Controller, showing one instance protecting traditional Web applications and one protecting API applications.

How to use this snippet:

The code can be applied manually through kubectl commands or as a part of a CI/CD pipeline.


Code :
