Traefik is a modern reverse proxy aimed towards applications running through container orchestrators.

Some of the benefits of using Traefik over NGinx are:

• Real-time configuration changes - no need to reload the proxy
• Auto discovery and configuration of services through a vast amount of container orchestrators.
• Built-in official support for Let's Encrypt SSL with certificate auto-renewal
• Supports path-based routing without need to hard-code it in global config.

• BTCPAYGEN_REVERSEPROXY to traefik.
• LETSENCRYPT_EMAIL: Optional, The email Let's Encrypt will use to notify you about certificate expiration.
• BTCPAYGEN_ADDITIONAL_FRAGMENTS: Add traefik
• BTCPAY_ADDITIONAL_HOSTS: Traefik can not accept list of hosts. Add additional hosts in a new file named e.g. btcpayserver-traefic.custom.yml:

  version: "3"
  services:
    btcpayserver:
      labels:
        traefik.http.routers.btcpayserver2.rule: Host(`additional.example.com`)
        traefik.http.routers.btcpayserver3.rule: Host(`another-additional.example.com`)
