Traefik behind AWS ELB. X-Forwarded-For header

Traefik v1.7 is running within a Docker Swarm, functioning as a global service. Consequently, an instance of Traefik is deployed for each host within our Docker Swarm cluster. It is important to note that the Swarm’s routing mesh is not employed in this setup. Instead, the port mode is configured as “host,” allowing the port to be attached to the host’s network.

Docker Swarm deployed to AWS and lives behind internal/external load balancers (Classic type).

Custom error page in Traefik v2.x. Finally

What you will learn today 🦦:

what is Traefik and why I decisively recommend to use it with Docker Swarm
how to show custom error page if Traefik returns 404 (service not found)

How I met Traefik 😁

Traefik is a top modern reverse proxy and load balancer. I started to use it from major version 1. At that moment, I already had Docker Swarm cluster, which I began to prepare for production use, and only one thing in the coherent picture has been left: “External Load Balancer”. Official docker doc had an example with HaProxy so it was obvious to try it out first. As I remember it took a significant amount of time to get HaProxy works smoothly with Swarm. But I wasn’t satisfied with the result:
