Wildcard subdomains with ssl via load balancer
I am developing a SAAS platform and require a subdomain for each signup, in theory it would be possible to create a new record for each subdomain as someone signs up but this creates overhead that doesn’t exist if wildcard ssl certificates are supported.
I note from the Loadbalancer documentation they are not.
With that said, what would be your recommendation to get past this?
Please note, I am looking for a solution that doesnt require provisioning subdomains for each new sign up.. Not least because of the rate limits on Lets Encrypt (50 certs a week per registered domain), we could of course use a combination of 100 names per cert to get that up to 5k a week which would probably be fine but again that is additional overhead for something which could be very simple.
