kubernetes nginx ingress confusion

[jules]

I'm trying to get a feel for the Kubernetes Nginx ingress controller. Trying to deploy it to an AKS cluster, however I can't figure out the following. According to https://docs.microsoft.com/en-us/azure/aks/ingress-basic?tabs=azure-cli

To control image versions, you'll want to import them into your own Azure Container Registry. The NGINX ingress controller Helm chart relies on three container images. Use az acr import to import those images into your ACR.

So, I've pulled, tagged and pushed the controller, patch and default backend images to ACR.

Next, did helm show values ingress/nginx/ingress-nginx > values.yaml and created a new .yaml to reference it a installation time (so that it can grab the images from ACR rather than the default repo).

However, after install I'm surprised to find only 1 pod related to nginx

NAME                                           READY   STATUS    RESTARTS   AGE
ingress-nginx-controller-764784f688-qbbq8      1/1     Running   0          49m

I've even tried to install it with the defaults without providing my own .yaml with -f foo.yaml like this:

 helm upgrade --install ingress-nginx ingress-nginx   --repo https://kubernetes.github.io/ingress-nginx   --namespace ingress-nginx --create-namespace

But still only 1 pod:

NAME                                        READY   STATUS    RESTARTS   AGE
ingress-nginx-controller-6bf7bc7f94-ml4js   1/1     Running   0          55s

Per my understanding this is what gets created:

What am I missing please ?

ingress-nginx-controller-6bf7bc7f94-ml4js looks like a pod. Pods are not containers but they can contain containers. Why don't you describe it and see what containers it contains.
