Save 20% on UptimeRobot today! https://l.technotim.live/uptime-robot-technotim In today's Traefik tutorial we'll get FREE Wildcard certificates to use in our HomeLab and with all of our internal self-hosted services. We're going to set up Traefik 3 in Docker and get Let's Encrypt certificates using Cloudflare as our DNS Provider (we'll cover how to set up others too). Then we'll configure local DNS using PiHole (or any other local DNS) to route to our services that are now protected with secure certificates! Thanks to UptimeRobot for sponsoring today's video!
