DigitalOcean Kubernetes: All pages are 404

Traefik Traefik v2
1

Hey, everyone!

I've been trying to get a very basic configuration of Traefik running on DigitalOcean Kubernetes. While it seems like I can get it running, every page I try to visit returns 404. I was hoping to get some help here.

Here are the steps I'm taking:

  1. Create a Kubernetes cluster with two nodes from the DigitalOcean dashboard version (1.16.6-do.2)
  2. Run doctl kubernetes cluster kubeconfig save <cluster name> to save kubectl configuration
  3. With Helm 3.1.2, Run helm repo add traefik https://containous.github.io/traefik-helm-chart
  4. Run helm repo update
  5. Run helm install traefik traefik/traefik
  6. Run kubectl get svc traefik --namespace default -w and wait for an external IP address to appear
  7. When an external IP address appears ensure that it matches a newly-created Load Balancer in the DigitalOcean dashboard
  8. Set up the following record in /etc/hosts: <External IP Address> example.com
  9. Run kubectl apply -f whoami.yml (see below for contents)

All of these steps complete with no errors. However, when I attempt to visit example.com, I get a page which says 404 page not found (plain text, no styling).

Has anyone here gotten Traefik 2 working with DigitalOcean Kubernetes? The following is the contents of whoami.yml from step 9:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: whoami-deployment
spec:
  replicas: 1
  selector:
    matchLabels:
      app: whoami
  template:
    metadata:
      labels:
        app: whoami
    spec:
      containers:
        - name: whoami-container
          image: containous/whoami

apiVersion: v1
kind: Service
metadata:
  name: whoami-service
spec:
  ports:
    - name: http
      targetPort: 80
      port: 80
  selector:
    app: whoami
---
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: whoami-ingress
  annotations:
    kubernetes.io/ingress.class: traefik
spec:
  rules:
    - host: example.com
      http:
        paths:
          - path: /
            backend:
              serviceName: whoami-service
              servicePort: http

I've been able to get an Nginx ingress running using the guide available here, so I know I must be doing something wrong as far as Traefik is concerned: https://www.digitalocean.com/community/tutorials/how-to-set-up-an-nginx-ingress-with-cert-manager-on-digitalocean-kubernetes

I was facing same kind of problem when I deployed Traefik 2. Hope below 2 links(which helped me) will help you.

I figured out my issue. I needed to specify a static config to enable the kubernetes ingress configuration source. I did this by changing step 5 to be helm install --set="additionalArguments={--providers.kubernetesingress=true}" traefik traefik/traefik
