Exam 5 Q7 - helm charts

Can someone more skillful in Helm explain how the heck I have to figure out and know that chart I have to look for is NGINX ?!?!? What keywords I should check or follow ? the fact, that chart I have to look for is NGINX is coming out of the bushes for me! Please, clarify!

Note that there aren’t that many charts to check. We can see this by doing:

cluster1-controlplane ~ ➜  helm ls -A
NAME                            NAMESPACE       REVISION        UPDATED                                  STATUS          CHART                           APP VERSION
lvm-crystal-apd                 crystal-apd-ns  1               2025-08-17 19:34:59.398446729 +0000 UTC  deployed        nginx-1.3.0                     1.17.5     
my-vertical-pod-autoscaler      kube-system     1               2025-08-17 19:33:52.754817241 +0000 UTC  deployed        vertical-pod-autoscaler-1.8.0   1.3.0      

So we see from that that currently, the nginx-1.3.0 chart is installed at that release name in the crystal-apd-ns namespace. In addition, only a single repo is defined in the cluster:

cluster1-controlplane ~ ➜  helm repo ls
NAME            URL                              
kubesphere      https://charts.kubesphere.io/main

and we can search for nginx repos by doing

cluster1-controlplane ~ ➜  helm search repo nginx
NAME                                    CHART VERSION   APP VERSION     DESCRIPTION                                       
kubesphere/nginx                        1.3.5           1.18.0          nginx is an HTTP and reverse proxy server, a ma...
kubesphere/apisix-ingress-controller    0.8.0           1.3.0           Apache APISIX Ingress Controller for Kubernetes   

which gives you a clear answer.

Indeed! How I did not pay attention to it? Thank you very much!
