How to setup kubernetes nginx ingress without load balancer?

2/14/2019

I'm trying to create an nginx-ingress for my 2 services without LB. First, I create nginx_ingress.yaml:

kind: Service
apiVersion: v1
metadata:
  name: ingress-nginx
  namespace: ingress-nginx
  labels:
    app: ingress-nginx
spec:
  selector:
    app: ingress-nginx
  type: NodePort
  ports:
    - name: http
      port: 80
      targetPort: http
    - name: https
      port: 443
      targetPort: https
---

And then echo_ingress.yaml:

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: echo-ingress
spec:
  rules:
  - host: subdomain1.example.com
    http:
      paths:
      - backend:
          serviceName: echo1
          servicePort: 80
  - host: subdomain2.example.com
    http:
      paths:
      - backend:
          serviceName: echo2
          servicePort: 80

But, when ingress was created, it doesn't show its address and it seems not running properly, I cannot get anything from port 80 on curl:

NAME           HOSTS                                  ADDRESS   PORTS   AGE
echo-ingress   git.satelkom.co.id,op.satelkom.co.id             80      8m9s

What's going wrong here?

If you try to define path ?

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: echo-ingress
spec:
  rules:
  - host: subdomain1.example.com
    http:
      paths:
      - backend:
          serviceName: echo1
          servicePort: 80
        path: /   # <--- Add this tag
  - host: subdomain2.example.com
    http:
      paths:
      - backend:
          serviceName: echo2
          servicePort: 80
        path: /   # <--- Add this tag

Or define external IPs on ingress service

kind: Service
apiVersion: v1
metadata:
  name: ingress-nginx
  namespace: ingress-nginx
  labels:
    app: ingress-nginx
spec:
  externalIPs:    # <-- Try to add this 2 lines
    - <YOUR IP LAN or WAN>
  selector:
    app: ingress-nginx
  type: NodePort
  ports:
    - name: http
      port: 80
      targetPort: http # <-- Replace by port number: 80
    - name: https
      port: 443
      targetPort: https # <-- Replace by port number: 443
