Issue: One of the questions in the lighting lab validation is failing

Details: There is a question on Helm chart in the lightening labs. The validation for that fails even if I try the Solution provided.
The question is about deploying nginx server after adding the Bitnami repository as polar. I have created a chart in the

right namespace with valid details. Still, the validation fails. I am curious to know if it is a glitch or if I am missing something
Attaching the screen shot for the same.

Works for me

kubectl config use-context cluster3
kubectl create ns cd-tool-apd
kubectl config set-context --current --namespace cd-tool-apd
helm repo add polar https://charts.bitnami.com/bitnami
helm repo update
helm pull polar/nginx
ls -l
helm install nginx-server nginx-15.3.3.tgz

Thanks for the response

I was missing these two commands

helm repo update
helm pull polar/nginx

Do we always need to update the repo and pull the image before installing? I believe it’s needed only when we want to modify the values Is that correct?

As you can see in my screenshot same version is installed as yours. But still, validation failed.

What was the sequence of commands you used that was causing the lab to mark incorrect?

NGINX can be accessed through the following DNS name from within your cluster:

nginx-server.cd-tool-apd.svc.cluster.local (port 80)

To access NGINX from outside the cluster, follow the steps below:

Get the NGINX URL by running these commands:

NOTE: It may take a few minutes for the LoadBalancer IP to be available.
Watch the status with: ‘kubectl get svc --namespace cd-tool-apd -w nginx-server’

export SERVICE_PORT=$(kubectl get --namespace cd-tool-apd -o jsonpath="{.spec.ports[0].port}" services nginx-server)
export SERVICE_IP=$(kubectl get svc --namespace cd-tool-apd nginx-server -o jsonpath='{.status.loadBalancer.ingress[0].ip}')
echo "http://${SERVICE_IP}:${SERVICE_PORT}"

It works now, Thanks Alistair!

To silence these warnings,

chmod 600 ~/.kube/config

Do they start after you have done some other question earlier? You shouldn’t be getting them.

Not sure ! It happened in that setup, Not seen after that
