Cloudflared and Traefik Integration Guide

This guide provides a step-by-step approach to integrate Cloudflared for secure tunneling and Traefik as an internal reverse proxy, focusing on the jobrain-system and JanssenProject/jans.

Objectives​

  • Secure the infrastructure by ensuring that the server is not exposed to the public internet.
  • Manage internal traffic efficiently using Traefik as a reverse proxy.
  • Integrate Cloudflare's Zero Trust model to secure applications.

Tasks​

Step 1: Environment Preparation​

  • Review the current setup of jobrain-system and JanssenProject/jans.
  • Check the server's resources and network configurations.

Step 2: Install and Configure Cloudflared​

  • Install cloudflared on the server.
  • Authenticate cloudflared with the Cloudflare account.
  • Create and configure a new tunnel for traffic routing.
  • Start the tunnel and ensure it's routing traffic correctly.
  • Configure DNS in Cloudflare to point the desired hostname to the tunnel's ID.

Step 3: Install and Configure Traefik​

  • Install Traefik on the server.
  • Create and configure the Traefik configuration file.
  • Define routers, services, and middlewares for jobrain-system and JanssenProject/jans.

Step 4: Integrate Cloudflare Zero Trust​

  • Configure Access policies in the Cloudflare dashboard.
  • Test the access control for the applications.

Step 5: Testing and Validation​

  • Test Cloudflared tunneling and Traefik's routing individually.
  • Perform end-to-end testing to ensure the entire flow works as expected.
  • Monitor logs and metrics to troubleshoot any potential issues.

Step 6: Documentation and Maintenance​

  • Document the architecture, configurations, and setup details.
  • Regularly update cloudflared, Traefik, and services to the latest versions.

Notes​

  • Ensure that each step is carefully executed and validated.
  • Regularly backup your configurations and have a recovery plan in place.
  • Monitor the system's performance and security posture continuously.
