I managed to deploy a python app at the kubernetes cluster . The python app image is deployed at AWS ECR (Elastic Container Registry).
My deployment is:

(NAME)charting-rest-server
(READY)1/1
(UP-TO-DATE)1
(AVAILABLE)1
(AGE)33m
(CONTAINERS)charting-rest-server
(IMAGES) *****.dkr.ecr.eu-west-2.amazonaws.com/charting-rest-server:latest
(SELECTOR)app=charting-rest-server

And my service is:

(NAME)charting-rest-server-service
(TYPE)LoadBalancer
(CLUSTER-IP)10.100.4.207
(EXTERNAL-IP)*******.eu-west-2.elb.amazonaws.com
(PORT(s))8765:32735/TCP
(AGE)124m
(SELECTOR)app=charting-rest-server

According to this AWS guide , when I do curl *****.us-west-2.elb.amazonaws.com:80 I should be able to externally access the Load Balancer , who is going to route me to my pod's ip.
But all I get is

(6) Could not resolve host: *******.eu-west-2.elb.amazonaws.com

And come to think about it if I want to have access to my pod and send some requests I should have an external-ip like 111.111.111.111 (obv an example).

EDIT

the deployment's yaml is:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: charting-rest-server
spec:
  selector:
    matchLabels:
      app: charting-rest-server
  replicas: 1
  template:
    metadata:
      labels:
        app: charting-rest-server
    spec:
      containers:
      - name: charting-rest-server
        image: *****.eu-west-2.amazonaws.com/charting-rest-server:latest
        ports: 
          - containerPort: 5000

the service's yaml:

apiVersion: v1
kind: Service
metadata:
  name:  charting-rest-server-service
spec:
  type: LoadBalancer
  selector:
    app: charting-rest-server
  ports:
    - protocol: TCP
      port: 80
      targetPort: 5000

I already tried with the suggestions from the comments , using an ingress instance but I only ended up spending a huge amount of time trying to understand how they work , "am I doing something wrong"?/etc .

I will put the yaml file I used here but it made no change since my ADDRESS field was empty - no ip to use.

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: charting-rest-server-ingress
spec:
  rules:
  - host: charting-rest-server-service
    http:
      paths:
      - path:/
        backend:
          serviceName: charting-rest-server-service
          servicePort: 80

I am stuck in that problem for so much time so I would appreciate some help.
