@Ayman - What the user is asking is after deploying the redis cluster in Challenge #4 - Kubernetes Challenges | KodeKloud, how do you verify the cluster is working fine?

@Effiok - There’s a button placed to verify whatever resources are created are in good shape or not.
If you are looking for configs needed to complete the challenge, here they are -
