- 🚀 How to Deploy Traefik Ingress Controller on Kubernetes using Helm with Prometheus & Grafana Integration.
Overview
Traefik is a cloud-native application proxy designed to simplify the deployment and management of microservices. It’s a reverse proxy and load balancer that automates service discovery, SSL/TLS termination, and routing, making it an ideal choice for modern containerized environments like Kubernetes.
Key Features:
1) Automated Service Discovery: Traefik integrates with popular orchestration tools like Docker, Kubernetes, Rancher, and Consul, automatically discovering services and injecting routes without manual configuration.
2) Cloud-Native: Designed from the ground up for cloud-native applications, Traefik provides a scalable and flexible solution for managing ingress traffic.
3) SSL/TLS Termination: Supports automatic issuance of Let’s Encrypt certificates and termination of SSL/TLS traffic.
4) Load Balancing: Offers various load balancing algorithms, including round-robin, least connection, and IP Hash.
5) Routing: Routes traffic to backend services based on URL patterns, headers, and other criteria.
6) Middlewares: Allows attaching custom middlewares to manipulate requests and responses.
7) Web UI: Provides a user-friendly web interface for monitoring and configuring Traefik.
Prerequisites
1) A Kubernetes 1.22+ 2) Helm version 3.9+ is installed
step 1
1.1: 🌟 Create a new namespace called traefik
kubectl create ns traefik
1.2: 🌟 Add Traefik Labs chart repository to Helm:
helm repo add traefik https://traefik.github.io/charts
1.3: 🌟 You can update & list the chart repository by running:
helm repo update
helm repo list
1.4: 🌟 And install it with the Helm command line:
helm install traefik traefik/traefik -n traefik
All Helm features are supported.
Examples are provided here
🌟 Installing with Custom Values
- You can set Traefik command line flags using
additionalArguments. Example of installation with logging set toDEBUG:helm install --namespace=traefik-v2 \ --set="additionalArguments={--log.level=DEBUG}" \ traefik traefik/traefik - You can also customize the installation by specifying custom values For that we need a file named
values.yaml. - values file
helm install traefik traefik/traefik -f values.yaml -n traefik
Step 2:🌟 Access Traefik dashboard without exposing it
This Chart does not expose the Traefik local dashboard by default.
Enabling the API in production is not recommended, because it will expose all configuration elements, including sensitive data.
2.1: Local Dashboard Access (Port-Forwarding)
The traefik admin port can be forwarded locally:
kubectl port-forward -n traefik $(kubectl get pods -n traefik --selector "app.kubernetes.io/name=traefik" --output=name) 8080:8080
This makes the dashboard accessible on the url: http://127.0.0.1:8080/dashboard/
Step 3: Integrate with Prometheus
If you want to access the
Traefikmetrics, on prometheus (prometheus satck), addrelease: promstackselector into serviceMonitor created in monitoring namespace. like below. If you have prometheus running in different namespace change the serviceMonitor namespace as required.
selector:
matchLabels:
release: promstack
3.1 Verify your Prometheus able to scrape Traefik metrics
-
Port Forward for prometheus service
-
Check for Prometheus Targets & search for traefik
Step 4: Visualize Metrics with Grafana Dashboard
4.1 Import the Official Traefik Grafana Dashboard
traefik-official-standalone-dashboard Import the dashboard template by
Copy ID to clipboard
4.2 Open Grafana in your browser
Click on Dashboards –> New –> Import. And paste the ID & click on
LoadChosse your prometheus data source, then click import.
