Cannot install nginx ingress with helm from nginx-stable when specifying namespace

Question

I have a question. I am trying to install nginx with helm 3 but it is not working when i specify the namespace. Any idea why ? it works without.

helm install nginx-release nginx-stable/nginx-ingres -n ingress-basic
Error: failed to download "nginx-stable/nginx-ingres" (hint: running `helm repo update` may help)

Answer 1

Your command has a typo, you typed nginx-stable/nginx-ingres and it should be nginx-stable/nginx-ingress.

Following the documentation, your are using the right repository for the official NGINX Ingress. To successfully install it using helm you have to run the following commands:

1. Add NGINX Helm repository:

   $ helm repo add nginx-stable https://helm.nginx.com/stable
   $ helm repo update
   

2. To install the chart with the release name my-release (my-release is the name that you choose):

   $ helm install my-release nginx-stable/nginx-ingress
   

In your scenario the command should look like this:

$ helm install nginx-release nginx-stable/nginx-ingress -n ingress-basic

Before running the above command, you have to create the namespace:

kubectl create namespace ingress-basic

Answer 2

You are trying to use a wrong stable repo.
Use this

helm install ingress-basic stable/nginx-ingress -n ingress-basic
