Mixing
Sign CSR with LetsEncrypt Wild card cert
I have successfully requested a wildcard cert for a domain I own.
Now I want to use a subdomain CNAME (manager.<MY_DOMAIN>.com) to be used on a different machine.
I've created a CSR from that machine and now I guess I need to sign this CSR somehow from my machine, where the wildcard cert is located.
However I don't know how.
I am using Ubuntu 14.04 Server and my letsencrypt cert is under /etc/letsencrypt/
Cheers

The signing is done by the CA (in this case, Let's Encrypt). You must submit the CSR to them.

If you already have a wildcard cert for *.example.com then you do not need another cert for subdomain.example.com. Just use the certificate and key files for *.example.com.
It is still valid to have a separate cert for specific subdomains though, so if you do not wish to use the wildcard *.example.com certificate files just follow the same process to get a new cert for subdomain.example.com specifically.
