Getting Started with Traefik Ingress Controller for Kubernetes (AWS EKS)

In the world of Kubernetes, managing traffic flow through a cluster is a crucial task. One of the most popular solutions for this is the Traefik Ingress Controller. This blog post will guide you through the process of setting up a Traefik Ingress Controller for your AWS EKS cluster.

What is Traefik?

Traefik is a modern HTTP reverse proxy and load balancer that makes deploying microservices easy. It supports several backends (Docker, Swarm, Kubernetes, Marathon, Consul, Etcd, Zookeeper, BoltDB, Rest API, file…) to manage its configuration automatically and dynamically.

Why Traefik for AWS EKS?

AWS EKS (Amazon Elastic Kubernetes Service) is a managed service that makes it easy to run Kubernetes on AWS without needing to install, operate, and maintain your own Kubernetes control plane or nodes. Traefik, being a Kubernetes-native ingress controller, integrates seamlessly with AWS EKS, providing a robust solution for routing traffic and balancing loads in your Kubernetes cluster.

Prerequisites

Before we begin, ensure you have the following:

• An AWS account
• AWS CLI installed and configured
• kubectl installed
• An EKS cluster up and running

Step 1: Install Helm

Helm is a package manager for Kubernetes that allows developers and operators to more easily package, configure, and deploy applications and services onto Kubernetes clusters. Install Helm by following the instructions on the official Helm installation documentation.

Step 2: Add Traefik’s Helm Chart Repository

Add the Traefik Helm Chart repository to your Helm repositories:

helm repo add traefik https://helm.traefik.io/traefik

Step 3: Install Traefik

Now, install Traefik using the Helm chart:

helm install traefik traefik/traefik

This command deploys Traefik on the Kubernetes cluster with the default configuration.

Step 4: Verify the Installation

To ensure Traefik has been installed correctly, run the following command:

kubectl get pods

You should see the Traefik pod running.

Step 5: Configure Ingress Route

Now, let’s create an IngressRoute. This is a Traefik custom resource, which defines how incoming requests are routed to services. Here’s an example:

apiVersion: traefik.containo.us/v1alpha1
kind: IngressRoute
metadata:
  name: myingressroute
spec:
  entryPoints:
    - web
  routes:
  - match: Host(`mydomain.com`) && PathPrefix(`/`)
    kind: Rule
    services:
    - name: myservice
      port: 80

Save this as myingressroute.yaml and apply it with kubectl apply -f myingressroute.yaml.

Conclusion

Traefik Ingress Controller is a powerful tool for managing traffic in your AWS EKS cluster. Its ease of installation and robust feature set make it an excellent choice for any Kubernetes deployment. With this guide, you should now have a basic understanding of how to get started with Traefik on AWS EKS.

Remember, this is just the beginning. Traefik offers many more features like automatic SSL certificate management, middleware for augmenting your applications' behaviors, and much more. Explore the official Traefik documentation to learn more.
