Could you write step by step how you reach the goal?

I've tried to create an certbot SAN-Cert with multiple domain-names and this worked like a charm using one cert for all! Thanks!

Shure :)

At first you should have a working Certbot of course. Setup for this depends on your Server-Setup of course. Certbot requires access due to "standalone-http(s)" mode of certbot or access through apache/nginx/haproxy (works as well if setup correctly). I'm using each of these variants.

Assuming you have a working setup and certbot-services can access your certbot service (running as http/s while certbot is running) the SAN setup is quit easy:

$> certbot -d domain1.com -d domain2.com -d domain3.com

if running in non-standalone mode (running apache/nginx) you can tell Certbot where the auth-tokens are stored to for external domain-approval:

-w /var/www/my-web-root

With the syntax given above the SAN-Cert for all given domains is stored in /etc/letsencrypt/live/domain1/

standalone-mode and web-root also can be configured in /etc/letsencrypt/cli.ini
