Just a simple question. How to create a wildard cert that covers all of my sub domains.
My system is an Ubuntu 18.04 server mydomain.us, running v3.0 LXD. I have multiple LXD containers. I also have a constainer hosting HAproxy. The host uses port (80, 443 and others) forwarding to HAproxy. HAproxy forwards to the containers based on subdomain such as test.mydomain.us.
My question is how to create a single cert that applies to all subdomains and where to create it…in the host or in the HAproxy container? I hope my description makes sense?
