I deployed grafana using helm and now it is running in pod. I can access it if I proxy port 3000 to my laptop. Im trying to point a domain grafana.something.com to that pod so I can access it externally. I have a domain in route53 that I can attach to a loadbalancer (Application Load Balancer, Network Load Balancer, Classic Load Balancer). That load balancer can forward traffic from port 80 to port 80 to a group of nodes (Let's leave port 443 for later). I'm really struggling with setting this up. Im sure there is something missing but I don't know what.
Basic diagram would look like this I imagine.

Domain in route53 (grafana.something.com)

Loadbalancer 80 to 80 (Application Load Balancer, Network Load Balancer, Classic Load Balancer) I guess that LB would forward traffic to port 80 to the below Ingress Controllers (Created when Grafana was deployed using Helm)

Group of EKS worker nodes

Ingress resource ?????

Pod Grafana is listening on port 3000. I can access it successfully after proxying to my laptop port 3000.
Given that it seems you don't have an Ingress Controller installed, if you have the aws cloud-provider configured in your K8S cluster you can follow this guide to install the Nginx Ingress controller using Helm.
By the end of the guide you should have a load balancer created for your ingress controller, point your Route53 record to it and create an Ingress that uses your grafana service. Example:
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
annotations:
kubernetes.io/ingress.class: nginx
nginx.ingress.kubernetes.io/app-root: /
nginx.ingress.kubernetes.io/enable-access-log: "true"
name: grafana-ingress
namespace: test
spec:
rules:
- host: grafana.something.com
http:
paths:
- backend:
serviceName: grafana
servicePort: 80
path: /The final traffic path would be:
Route53 -> ELB -> Ingress -> Service -> Pods
