How do I deploy a kubernetes traefik.containo.us middleware with Pulumi?

In this guide, we will deploy Traefik middleware in a Kubernetes cluster using Pulumi. Traefik is a popular reverse proxy and load balancer for microservices. We will define a middleware resource in a Kubernetes cluster to manage HTTP requests.

Steps to Deploy Traefik Middleware

1. Install Pulumi and Kubernetes Provider: Ensure you have Pulumi installed and configured with the Kubernetes provider.
2. Define Middleware Resource: We will define the middleware resource using the kubernetes Pulumi package.
3. Deploy Middleware: Deploy the middleware to your Kubernetes cluster.

Below is the complete Pulumi program to deploy Traefik middleware.

import * as pulumi from "@pulumi/pulumi";
import * as k8s from "@pulumi/kubernetes";

// Define the Traefik Middleware resource
const middleware = new k8s.apiextensions.CustomResource("middleware", {
    apiVersion: "traefik.containo.us/v1alpha1",
    kind: "Middleware",
    metadata: {
        name: "test-middleware",
        namespace: "default",
    },
    spec: {
        stripPrefix: {
            prefixes: ["/api"],
        },
    },
});

// Export the name of the middleware
export const middlewareName = middleware.metadata.name;

Key Points

• Pulumi and Kubernetes Provider: Ensure Pulumi is installed and configured with the Kubernetes provider.
• Traefik Middleware Resource: The middleware is defined using the kubernetes.apiextensions.CustomResource class.
• Spec Configuration: The middleware is configured to strip the /api prefix from HTTP requests.
• Deployment: The middleware is deployed to the default namespace in the Kubernetes cluster.

Summary

We have successfully deployed Traefik middleware in a Kubernetes cluster using Pulumi. The middleware is configured to strip the /api prefix from incoming HTTP requests. This setup can be extended to include additional middleware configurations as needed.
