Prerequisites

• Ensure you have a Kubernetes cluster set up.
• Install Helm for package management.
• Have a domain name that resolves to the public IP of your Kubernetes cluster.

Installing Traefik via Helm

To install Traefik using Helm, configure the traefik-values.yaml file:

    ### traefik-values.yaml
      logs:
        general:
          level: DEBUG

      service:
        type: LoadBalancer

      certificatesResolvers:
        letsencrypt:
          acme:
            email: "[email protected]"
            storage: "traefik-acme.json"
            keyType: "RSA4096"
            tlsChallenge: {}
  

Configuring DNS for Traefik

After installing Traefik, set up a DNS name for the public IP of the Traefik controller:

kubectl get svc traefik -n kube-system -o jsonpath={.status.loadBalancer.ingress.hostname}

Deploying a Sample Application

To test Traefik, deploy a sample application like azure-vote-app.

Using IngressRoute CRD

Traefik supports the IngressRoute CRD for advanced routing configurations.
