While waiting and talking to your crush, from time to time, you check the number displayed on the counter to see if it's your turn already.

Then at some point, it finally is your turn. You go to the counter, get your burgers and come back to the table.

## Cluster en mode Docker Swarm avec Traefik et HTTPS

Vous pouvez avoir un cluster en mode Docker Swarm configuré en quelques minutes (environ 20 min) avec un processus Traefik principal gérant HTTPS (y compris l'acquisition et le renouvellement des certificats).

En utilisant le mode Docker Swarm, vous pouvez commencer par un "cluster" d'une seule machine (il peut même s'agir

    callbacks=callback_router3.routes,
)

## _Cluster_ de Docker Swarm Mode com Traefik e HTTPS

Você pode ter um _cluster_ de Docker Swarm Mode configurado em minutos (cerca de 20) com o Traefik controlando HTTPS (incluindo aquisição e renovação de certificados).
