But only because it works so easily with docker !! I remember a time where I though that you need a diploma and read/learn/understand a 10000 page dictionary to make nginx work properly.
Also hated the syntax of nginx… It can look so ugly and gibberish :/.
But I do believe Nginx is superior and more mature in many more aspects than Treafik. Still, Traefik is a breeze and is in IMO way easier to configure with docker than Nginx.
