Traefik quickstart setup - connection refused

Traefik Traefik v2
1

Hi there,

First time poster here!

I am trying to use minimal k8s Traefik configuration from official website as Kubernetes Ingress in minikube. When configuration proves good enough it would go on GCP with 1.18.20 GKE. After setup, when I try to curl http://example.com/bar there is an error curl: (7) Failed to connect to example.com port 80: Connection refused.

My setup is:

$ cat /etc/os-release

Any idea what might be wrong? Configuration is copy-paste from official resources.

Hey @ImmortalPawn

If I correctly understood you, you have to deploy Minikube and deploy Traefik as Ingress Controller on your MInikube cluster.

You have ensured that you can reach port 80 that is exposed by Minikube. minikube ip should return the IP address that it is listening on.

You have to also check on your cluster whether you have correctly created Kubernetes resource: load balancing service that exposes Traefik outside your cluster.

I encourage you to see our workshop on how to start with Traefik on Kubernetes to learn more about basic configuration:

Yes, that is right.

Yes I have. It is exposed and reachable.

You have to also check on your cluster whether you have correctly created Kubernetes resource: load balancing service that exposes Traefik outside your cluster.

minikube tunnel is used to ensure that Traefik service (load balancer) is reachable outside of the cluster.

I will check it. Thanks for suggestion.
