@prathiabhishek I have checked and could see that the lab is working fine. . I have tried with both labels tier=frontend as well as tier=nginx and could not find any issue.
Could you please recheck and let us know issue persists.
Thanks for your reply. My bad I’ve edited the file but forgot to run kubectl create -f replicaset-definition-2.yml. Hence the error.
No worries. Good luck @prathiabhishek
