Rails49 Docker App
Traefik
Requires a Cloudflare API token with DNS-01 challenge support.
- Zone / DNS / Edit: This allows Traefik to create and delete the _acme-challenge TXT records.
- Zone / Zone / Read: This allows Traefik to find the correct Zone ID for your domain.
Steps to create the token: 1. Go to My Profile > API Tokens in your Cloudflare dashboard. 2. Click Create Token. 3. Choose Create Custom Token. 4. Name it (e.g., Traefik DNS Challenge). 5. Add the two permissions mentioned above. 6. Under Zone Resources, select Include > Specific zone > rails49.org (or "All zones" if you prefer). Copy the generated token immediately (it won't be shown again).
Then copy the token to the .env file:
RAILS_DOMAIN=rails49.org
CF_DNS_API_TOKEN=your_new_token_here
Configure DNS Resolution on you Router
Configure the router for local dns resolution. My router (a GL.iNet) allows editing the hosts file under Network > DNS. Add the following (update the IP addresses):
192.168.8.235 rails49.org
192.168.8.235 code.rails49.org
