Ingress vs Traefik

Ingress vs Traefik? Which one is better for you?

In Kubernetes, exposing services to the outside world is a common requirement—whether you’re running APIs, web apps, or dashboards.

Routing this external traffic to the right pods securely and efficiently is where Ingress and Ingress controllers come in.

Among the popular ingress controllers, Traefik has gained widespread adoption due to its dynamic configuration capabilities, rich feature set, and seamless integration with Kubernetes.

However, many users—especially those new to Kubernetes networking—confuse the terms “Ingress” and “Traefik” or use them interchangeably.

In reality, Ingress is a Kubernetes-native API resource that defines routing rules, while Traefik is one of several Ingress controller implementations that enforce those rules.

In this post, we’ll break down the distinction between Kubernetes Ingress and Traefik, helping you understand:

  • What Ingress is and how it fits into Kubernetes networking

  • What Traefik does and how it differs from or complements Ingress

  • When to use Traefik directly vs. leveraging Ingress resources

We’ll also highlight real-world scenarios, pros and cons of each, and best practices for deploying either in production.

What is Traefik?

Traefik is a modern, cloud-native reverse proxy and load balancer designed to seamlessly integrate with dynamic infrastructure.

It acts as a gateway to your services, intelligently routing traffic while offering features like automatic SSL, metrics, retries, and circuit breakers out of the box.

Unlike traditional reverse proxies, Traefik was built from the ground up to support modern orchestrators such as Kubernetes, Docker, Consul, Nomad, and others.

Its standout feature is automatic service discovery—as services spin up or down, Traefik updates its routing configuration on the fly, without needing restarts.

Key Features of Traefik:

  • Kubernetes-native: Traefik works as an Ingress Controller in Kubernetes, responding to Ingress resources and custom CRDs like IngressRoute

  • Dynamic configuration: Automatically adjusts routing rules based on real-time changes in the cluster

  • Built-in Let’s Encrypt integration: Easily enables TLS with automatic certificate management

  • Rich observability: Native integration with Prometheus, Grafana, and other monitoring tools

  • Dashboard UI: A visual interface to view and manage traffic flow

Example Helm Install (Simplified)

bash
helm repo add traefik https://traefik.github.io/charts
helm repo update
helm install traefik traefik/traefik

Once deployed, Traefik listens to your Kubernetes resources and dynamically manages traffic routing based on the configuration.

Traefik is especially powerful for multi-cloud, hybrid, or developer-first environments where automation and simplicity are prioritized.

For example, it’s often used in GitOps workflows or edge service meshes.

Ingress vs Traefik: Key Differences

While “Ingress” and “Traefik” are often mentioned together, they operate at different levels in the Kubernetes networking stack.

One is a resource definition, the other is an implementation—but there are still important distinctions to understand, especially when deciding how to manage traffic in your Kubernetes environment.

Key Takeaway

  • Ingress is a Kubernetes-native API that specifies how external traffic should be routed, but it doesn’t do anything without a controller.

  • Traefik is one such controller—but it goes beyond just supporting Ingress.

    It brings modern features, automatic service discovery, and out-of-the-box TLS and observability, making it especially popular in cloud-native environments.

When to Use Kubernetes Ingress

Kubernetes Ingress is ideal when your routing requirements are straightforward and you want to stick with native Kubernetes patterns.

It provides a clean, declarative way to expose services using standard YAML and is compatible with a wide range of ingress controllers like NGINX, HAProxy, and Traefik.

Simple Routing Needs

If your application only requires basic HTTP/HTTPS routing—such as host-based or path-based routing—then Kubernetes Ingress offers a clean and native solution.

It’s a good fit when you:

  • Have a few services to expose externally

  • Need basic traffic routing without advanced logic

  • Want to manage everything through standard Kubernetes manifests

Using NGINX or Other Ingress Controllers

Kubernetes Ingress is controller-agnostic, meaning it works with any compatible ingress controller, including NGINX, HAProxy, and Contour.

This flexibility allows you to plug in a controller that best fits your needs while still using the familiar Ingress resource format.

You can also read our guide on Ingress vs NGINX to understand how the two relate and complement each other.

Standard Kubernetes Setup

For teams adopting Kubernetes with a focus on simplicity and maintainability, using the native Ingress API allows for:

  • Easier onboarding and documentation

  • Compatibility with cloud providers and managed Kubernetes offerings

  • Standardization across environments

If you’re running on bare-metal, consider pairing Ingress with MetalLB for LoadBalancer support—check our comparison MetalLB vs NGINX for more details.


When to Use Traefik

Traefik shines in dynamic and complex Kubernetes environments where you need flexibility, automation, and advanced observability.

As a modern cloud-native reverse proxy, it’s more than just an ingress controller—it’s a smart traffic manager.

Need for Dynamic Configuration

Traefik is designed for dynamic environments. It automatically discovers new services and applies routing rules in real-time—no need to reload or restart.

This makes it an excellent choice for teams deploying via CI/CD pipelines or operating in highly dynamic microservice architectures.

Its support for Kubernetes CRDs also allows fine-grained control with richer configuration options compared to standard Ingress resources.

Multi-Protocol Support (HTTP, TCP, etc.)

While Kubernetes Ingress primarily focuses on HTTP/S traffic, Traefik supports both Layer 7 (HTTP/S) and Layer 4 (TCP/UDP) protocols.

This means you can route not just web traffic but also databases, messaging systems, and custom TCP services using a unified configuration.

This multi-protocol support is covered in more detail in our post on Kubernetes Ingress vs LoadBalancer, where Traefik can often replace multiple networking components.

Built-in Observability and Metrics

Traefik includes native observability features out of the box:

  • A web dashboard to view routes and services

  • Metrics integration with Prometheus, Grafana, and Datadog

  • Access logs, tracing (Jaeger, Zipkin), and real-time health info

This is a big plus if you value visibility into your traffic flow and want to minimize third-party monitoring setup.

Integrations with Let’s Encrypt, Consul, etc.

Traefik has first-class integration with Let’s Encrypt, making automatic TLS certificate management effortless.

It also supports service discovery with Consul, Docker, ECS, and Nomad, which makes it highly versatile across container ecosystems—not just Kubernetes.

Deploying Traefik as an Ingress Controller

Traefik can be seamlessly deployed in a Kubernetes cluster as an Ingress Controller.

It supports both standard Kubernetes Ingress resources and its own powerful Custom Resource Definitions (CRDs) for advanced configurations.

Here’s how to get started.

🚀 Helm Chart Installation Steps

The easiest and most common way to install Traefik in Kubernetes is via the official Helm chart.

Make sure you have Helm installed and a working Kubernetes cluster.

bash
helm repo add traefik https://traefik.github.io/charts
helm repo update
helm install traefik traefik/traefik \
–namespace traefik \
–create-namespace

This installs Traefik in its own namespace (traefik) with default settings, including its built-in dashboard.

🔎 Related: If you want to expose Traefik in a bare-metal environment, consider using MetalLB alongside it. We explain this combo in our MetalLB vs NGINX post.

📦 CRDs vs Standard Ingress Objects

Once installed, Traefik supports two main ways to configure routing:

1. Standard Ingress Resources

Traefik can interpret Kubernetes-native Ingress objects just like any other Ingress Controller (e.g., NGINX).

This is ideal for users who prefer to stick with the standard API.

Example:

yaml
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
name: my-app
annotations:
kubernetes.io/ingress.class: traefik
spec:
rules:
- host: myapp.example.com
http:
paths:
- path: /
pathType: Prefix
backend:
service:
name: my-service
port:
number: 80

2. Traefik CRDs (IngressRoute, Middleware, etc.)

For more advanced use cases like custom headers, redirect rules, retries, rate limiting, and circuit breakers, Traefik provides its own CRDs.

These offer deeper control and flexibility.

Example of an IngressRoute:

yaml
apiVersion: traefik.containo.us/v1alpha1
kind: IngressRoute
metadata:
name: my-custom-route
spec:
entryPoints:
- web
routes:
- match: Host(`myapp.example.com`)
kind: Rule
services:
- name: my-service
port: 80

Example Use Case

You might use Traefik with CRDs to:

  • Apply rate limiting to a specific route

  • Add custom error pages

  • Set up automatic HTTPS with Let’s Encrypt

  • Redirect HTTP to HTTPS on the fly

This makes it ideal for teams that want smart routing without managing complex config files.


Ingress vs Traefik: Real-World Comparison Use Case

To better understand the practical differences between Kubernetes Ingress (with NGINX) and Traefik, let’s walk through a real-world example: routing three microservices under different subdomains.

🎯 Scenario

You have three services:

  • auth-service exposed at auth.example.com

  • api-service exposed at api.example.com

  • web-service exposed at www.example.com

You want:

  • Host-based routing

  • TLS termination

  • Metrics for monitoring

  • Optional rate limiting

🔧 Using Ingress + NGINX

You’d deploy the NGINX Ingress Controller and create one Ingress resource for each service:

Ingress for auth-service:

yaml
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
name: auth-ingress
annotations:
nginx.ingress.kubernetes.io/rewrite-target: /
nginx.ingress.kubernetes.io/ssl-redirect: "true"
spec:
tls:
- hosts:
- auth.example.com
secretName: auth-tls
rules:
- host: auth.example.com
http:
paths:
- path: /
pathType: Prefix
backend:
service:
name: auth-service
port:
number: 80

You’d repeat similar YAML for api-service and web-service.

Observability: Requires integration with Prometheus or an NGINX exporter.

Rate Limiting: Achievable via annotations, but limited compared to Traefik.

🚀 Using Traefik

With Traefik’s CRDs, you can define an IngressRoute per service, with richer configuration options:

IngressRoute for auth-service:

yaml
apiVersion: traefik.containo.us/v1alpha1
kind: IngressRoute
metadata:
name: auth-route
spec:
entryPoints:
- websecure
routes:
- match: Host(`auth.example.com`)
kind: Rule
services:
- name: auth-service
port: 80
tls:
secretName: auth-tls

Traefik also allows central rate limiting and automatic Let’s Encrypt integration via Middleware and certResolvers.

Observability: Built-in dashboard + Prometheus metrics out of the box
TLS/HTTPS: Automatically handled via Let’s Encrypt (with minimal config)
Rate Limiting: Done via custom Middleware resource
