Typhon - can't configure ingress to work, always end up with default-backend and 404

@velimattiahod6eb232fc97763 wow I’ve been beating my head against this particular wall for over 3 hours! Thank you so much!

I had the same problem, solution was to add kubernetes.io/ingress.class: "public" to your ingress? Typhoon nginx-ingress addon says on startup

W0415 06:05:49.439051       5 flags.go:164] only Ingress with class "public" will be processed by this ingress controller

Your ingress ->

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: nginx
  annotations:
    kubernetes.io/ingress.class: "public"
spec:
  rules:
  - host: in.cloud.example.com
    http:
      paths:
      - path: /
        backend:
          serviceName: nginx
          servicePort: 80

Hey. Since I am no Kubernetes expert (yet :) ) I reached out to some of our engineers to take a look at your question. One of our engineers has suggested the following:

The ingress they posted specifies a service name nginx

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: nginx
  annotations:
    ingress.kubernetes.io/rewrite-target: /
spec:
  rules:
  - host: in.cloud.example.com
    http:
      paths:
      - path: /
        backend:
          serviceName: nginx
          servicePort: 80

but the kubectl get all output doesn’t have nginx service listed which seems like the issue

NAME                       TYPE        CLUSTER-IP     EXTERNAL-IP   PORT(S)          AGE
default-backend            ClusterIP   10.3.164.90    <none>        80/TCP           4h
nginx-ingress-controller   ClusterIP   10.3.230.155   <none>        80/TCP,443/TCP   4h

the default backend - 404 response is from the pod default-backend which the ingress controller falls back to if the ingress is misconfigured or there’s no matching hosts on the controller.

So it sounds like you need to specify nginx-ingress-controller instead of nginx in your configuration or create an nginx deployment frontend by an nginx service like this:

kind: Service
apiVersion: v1
metadata:
  name: nginx
spec:
  selector:
    app: nginx
  ports:
  - protocol: TCP
    port: 80
    targetPort: 80
---
apiVersion: apps/v1
kind: Deployment
metadata:
  name: nginx
  labels:
    app: nginx
spec:
  selector:
    matchLabels:
      app: nginx
  template:
    metadata:
      labels:
        app: nginx
    spec:
      containers:
      - name: nginx
        image: nginx:1.7.9
        resources:
          requests:
            cpu: 10m
        ports:
        - containerPort: 80
