FAQ

What is Traefik and why use it as a Kubernetes Ingress controller?

Traefik is a lightweight, cloud-native reverse proxy and load balancer that simplifies Kubernetes Ingress routing with automatic service discovery. It supports dynamic configuration, TLS termination, and integrates seamlessly with Helm for easy deployment.

How can I configure TLS/SSL in Traefik for secure connections?

Enable TLS in Traefik using certificate resolvers and an ACME provider like Let’s Encrypt. Define TLS settings in values.yaml:

certResolvers:
  letsencrypt:
    email: "your-email@example.com"
    storage: /data/acme.json
    caServer: https://acme-v02.api.letsencrypt.org/directory

Apply TLS to your IngressRoute by specifying a TLS secret or using a certificate resolver.

Kubernetes Ingress: Traefik vs. Nginx – Which is Better?

Traefik and Nginx are both popular Kubernetes Ingress controllers, but they have different strengths:

  • Traefik is dynamic, cloud-native, and supports automatic service discovery, built-in Let's Encrypt TLS, and middleware for traffic shaping. It’s ideal for modern microservices and GitOps workflows.
  • Nginx is a more traditional and stable solution with extensive configuration options, better performance under high traffic loads, and stronger community support for classic HTTP-based applications.

If you need real-time configuration updates, automatic certificate management, and dynamic routing, go with Traefik. If you need fine-grained configuration, high performance, and static stability, Nginx may be the better choice.

How to Install Traefik Ingress Controller on Kubernetes?

Add the Traefik Helm repo, update it, create a namespace, and install Traefik:

# Add the Traefik Helm repository
helm repo add traefik https://traefik.github.io/charts

# Update Helm repositories
helm repo update

# Create a namespace for Traefik
kubectl create namespace traefik

# Install Traefik using Helm in the 'traefik' namespace
helm install traefik traefik/traefik --namespace traefik

Customize the deployment by modifying values.yaml or using Helm CLI flags.

How to Set Up Kubernetes Dashboard Ingress with Traefik?

Create an IngressRoute to expose the Kubernetes dashboard through Traefik:

apiVersion: traefik.io/v1alpha1
kind: IngressRoute
metadata:
  name: kubernetes-dashboard
spec:
  entryPoints:
    - websecure
  routes:
    - match: Host(`dashboard.example.com`)
      kind: Rule
      services:
        - name: kubernetes-dashboard
          port: 443
  tls: {}

Secure access using authentication middleware or TLS certificates.

How to Configure Kubernetes Ingress Controller with Traefik?

Define Ingress objects using Kubernetes IngressRoute CRDs or standard Ingress resources. Set entry points, routes, and middlewares in values.yaml. Example:

providers:
  kubernetesCRD:
    enabled: true
  kubernetesIngress:
    enabled: true

This enables Traefik to manage ingress traffic dynamically.

What is Kubernetes Ingress Traefik and How Does It Work?

Traefik is an Ingress controller that routes external traffic to Kubernetes services. It dynamically discovers services, applies routing rules, and supports TLS termination, middleware, and load balancing. Traefik integrates with Helm, CRDs, and Kubernetes annotations for flexible configuration.

How to Rewrite Target Paths in Traefik Kubernetes Ingress?

Use the rewrite-target annotation or middleware to modify request paths dynamically:

apiVersion: traefik.io/v1alpha1
kind: Middleware
metadata:
  name: rewrite-path
spec:
  replacePath:
    path: "/new-path"

Apply the middleware to your IngressRoute to rewrite URLs for backend services.
