What you should have ready:

  • Your running Docker container from Ep 6
  • A free Cloudflare account

  2. How does Cloudflare protect you? (It stands in front like a bodyguard).

By the End

After this lesson, you'll:

  • ✅ Connect your local game to the global internet
  • ✅ Have a real https:// link to share with friends
  • ✅ Pay exactly $0.00 for hosting!
