Nginx ingress chapter host rules point to the wrong service port

[v-ctiutiu]

Description

As per discussion #149 seems that a mistake slipped, and nginx rules used in the ingress chapter point to the container port (8080). Nginx ingress controller rules should point to service port, not container port.

The echo deployment spec looks like below:

...
spec:
    containers:
      - name: echo
        image: jmalloc/echo-server
        ports:
          - name: http
            containerPort: 8080
...

The echo service spec looks like below:

...
spec:
  ports:
    - name: http
      port: 80
      targetPort: 8080
...

The ingress host rule spec for the echo service should look like:

...
spec:
  rules:
    - host: echo.starter-kit.online
      http:
        paths:
          - path: /
            pathType: Prefix
            backend:
              service:
                name: echo
                port:
                  number: 80
