New member and new to deploying my own SSL cert. Tried to research my question on my own. So this might have been asked before so perhaps my google-fu is weak. Right now I am in the planning stage of my project - which is to deploy a web server using a sub domain - example foo.hamies.world
I have an existing wild card SSL cert deployed on another application. My DNS provider is cloudflare. I used the dns-01 method via the acme package.
The question(s) are:
Do I need to generate a new cert for my sub domain? I don’t think I need to - since I have a wild card ssl cert (would like to confirm).
Can I use my existing ssl cert on the new server hosting the new sub domain?
My domain is:
I ran this command:
It produced this output:
My web server is (include version):
The operating system my web server runs on is (include version):
Ubuntu 18.04.4 LTS
My hosting provider, if applicable, is:
I can login to a root shell on my machine (yes or no, or I don’t know): Yes
I’m using a control panel to manage my site (no, or provide the name and version of the control panel):
The version of my client is (e.g. output of
certbot --version or
certbot-auto --version if you’re using Certbot):
