Secure sub-domains only

Hi! I have a main domain, let’s call it example.com on one server, then I have admin.example.com on a different server and dev.example.com on another server.
What is the best way to generate SSL certificates only for each subdomain, leaving the main domain unmodified.

My domain is: example.dom

My web server is : Nginx

The operating system my web server runs on is : Ubuntu 18.04

My hosting provider, if applicable, is: AWS

I can login to a root shell on my machine: yes

Hi @manus

there is no “best way”.

Create these two certificates, job is done. There is no relation required between your main domain and your subdomains.

If the systems can individually run ACME clients, then you can treat them as separate systems.
Each doing only the local FQDN.
