Kubernetes ingress: could not connect?

Traffic flow to implement:

client ---> Ingress (SSL,LoadBalancer) --> my_web(service) -> PODs

Ingress:

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: foo

spec:
  ingressClassName: nginx

  rules:
    - host: "test.foo.com"
      http:
        paths:
          - pathType: Prefix
            path: "/"
            backend:
              service:
                name: my_web
                port:
                  number: 8080

Could not connect ingress port 80:

curl http://test.foo.com:80      <--- could not connect

test.foo.com is mapped to 127.0.0.1 in hosts file.

Could connect to the my_web service (loadBalancer) directly

curl http://localhost:8080    <---- success

Does ingress expose any port externally?

my_web_service.yaml

apiVersion: v1
kind: Service
metadata:
  name: my_web
  labels:
    app: my_web
spec:
  ports:
    - name: http
      port: 8080
      targetPort: 8080
  selector:
    app: my_web
  type: LoadBalancer

my_web_deployment.yaml

apiVersion: apps/v1
kind: Deployment
metadata:
  name: my_web
  labels:
    app: my_web
spec:
  selector:
    matchLabels:
      app: my_web
  template:
    metadata:
      labels:
        app: my_web
    spec:
      containers:
        - image: my_web:latest
          name: my_web
          ports:
            - containerPort: 8080

Ingress itself does not expose ports if you don't configure a loadbalancer service for the ingress implementation.

Use

curl http://test.foo.com:8080

in your case
