What problems can you run into when trying to configure nginx to work with 5000 domains?

Question

Nginx

What problems can you face when trying to configure nginx to work with 1500 - 5000 subdomains of one domain via hhtps / http
I want to save money on buying a wildcard certificate, but at the same time I need to issue a subdomain accessible via https to each site user.
For domains like u1.site.ru ... u2.site.ru ... u4999.site.ru
I want to use Let's Encrypt to get certificates, but I'm a little worried about the need to create a gigantic config for nginx. At the same time, nginx works as a reverse proxy and its whole task is to decrypt traffic and transfer it to another port of the same server.

Answer 1

With Let's Encrypt, you won't succeed. There you can create 7 certificates per week from one server, and 5 per week for one domain. Those. in 3 months you can get a maximum of ~ 60 certificates for subdomains
