Traefik on GKE

Project template to build an application running on Google Kubernetes Engine (GKE) with Traefik.

Requirements

This project just requires an existing cluster on GKE ond kubectl connected to it.

Run Treafik

During this setup, for the sake of simplicity we'll store the ACME (Automated Certificate Management Environment) configuration on a GCE disk. This will prohibit you from adding another pod to the Treafik deployment. To overcome this issue, use another way of storing Treaefik's acme.json.

First, create the GCE disk:

gcloud compute disks create --size=2GB --zone=your-region demo-acme

Second, update the following values in the config files in the traefik/ folder:

• <Email> in traefik/01_permissions.yml and traefik/03_config.yml
• example.com in traefik/03_config.yml to your domain pointing to your Kubernetes load balancer (IP visible on GKE after deployment)
• if you want to create a separate ingress for the Treafik dashboard, also update traefik.example.com in traefik/06_ingress.yml to the domain you previously specified

After updating the values, apply the configuration to your Kubernetes cluster using the following command:

kubectl apply -f traefik/

If you don't need an ingress for the Traefik dashboard, just apply the config files 1 - 5.

Traefik should now be up & running on GKE. You can now point your domain to the IP of the load balancer (visible in Services & Ingress > treafik-ingress-controller).

Deploying a Demo Service

After Traefik is running, you can start deploying other services into the cluster. Traefik will automatically pick them up and create a frontend and backend according to the rules specified in the ingress definition.

To the deploy the whoami demo service from containous, first update the host rule in whoami/03_ingress.yml. After that deploy the service:

kubectl apply -f whoami/
