I know that currently (feb 2018) wild card certs are not yet available, but my question anticipates the availability in the near future.
I have serveral servers that split functionality of the same app.
- server1 serves: sub1.domain.com and all related sub domains: ss1.sub1.domain.com ss2.sub1.domain.com, ss3. sub1.domain.com
- server 2 serves: sub2.domain.com and all related sub domains, tt1. sub2.domain.com, tt2.sub2.domain.com, …
My goal is to limit the amount of certs and my question is formulated under the assumption that letsencrypt provides wild card certs.
My question is 2 fold.
Do i need multiple certs sinds a have multiple servers?
If yes, so If I need 2 certs for 2 servers, can these certs act a a wild card cert on sub1.domain.com and another cert on sub2.domain.com. In other words can a wild card cert also be on a subdomain (and related sub domains) or is a wild card cert only applicable on domain.com and not on sub1.domain.com ?
Thanks for shedding a light on this.
