Accessing multiple databases with the same IP across multiple subdomains?

Question

Nginx

Tell me please!
There is a need to create several PostgreSQL and MySQL servers located on the same global IP address (+ on the same server in docker containers), but for access to separate subdomains like db1.url.com:5432
db2.url.com:5432 In essence, something close to reverse-proxy in the usual sense is needed.
Is it possible to implement this? If so, how?

Answer 1

For example HAproxy
