How to publicly expose Traefik ingress controller on Google Cloud Container Engine?

Question

I've been trying to use Traefik as an Ingress Controller on Google Cloud's container engine.

I got my http deployment/service up and running (when I exposed it with a normal LoadBalancer, it was answering fine).

I then removed the LoadBalancer, and followed this tutorial: https://docs.traefik.io/user-guide/kubernetes/

So I got a new traefik-ingress-controller deployment and service, and an ingress for traefik's ui which I can access through the kubectl proxy.

I then create my ingress for my http service, but here comes my issue: I can't find a way to expose that externally.

I want it to be accessible by anybody via an external IP.

What am I missing?

Here is the output of kubectl get --export all :

Answer 1

You need to expose the Traefik service. Set the service spec type to LoadBalancer . Try the below service file that i've used previously:

apiVersion: v1
kind: Service
metadata:
  name: traefik
spec:
  type: LoadBalancer
  selector:
    app: traefik
    tier: proxy
  ports:
  - port: 80
    targetPort: 80
