Setting up traefik as Ingress controller for Kubernetes

Just my own experience setting up traefik as Ingress controller on Kubernetes.

brew install kubernetes-helm

helm init

Download the default values.yaml file and edit it depends on your needs. Then issue the below command.

I want to install it to kube-system namespace hence the --namespace kube-system.

helm install --name my-traefik --namespace kube-system --values values.yaml stable/traefik

If you make a mistake and want to remove it

helm delete --purge my-traefik

--purge if you want to reuse the name previously. Otherwise, helm will complain release xxx already exists.

You will have to create an Ingress, a service and a deployment.

Ingress is a rule to help you setup routing traffic from a domain to your cluster service name
Service will expose your pods to be accessible in the cluster by selector (see example)
Deployment is well .. your app deployment.

It will be a whole lot easier if you see this cheese.yaml file

Download the file and kubectl create -f traefik.yaml to deploy it to your cluster.

In the example above, i will use the domain stilton.example.com

Create a CNAME record of stilton.example.com to point to your traefik’s ELB public address.

If you have traefik dashboard enabled, you should see new ingress and the pods it distributes load to on the web.

PS: You don’t necessarily use helm. It just make installing stuff a lot easier.
