Automaticly remove DNS record after acme refresh #71

Open di-rect opened 3 months ago

di-rect commented 3 months ago

Hi,

There are various ways to remove records which I can implement but would it be possible to remove a record after acme updated the belonging certificate for a domain ?

Thanks,

I'm not sure what you mean, really; or how ACME is relevant for dynamic DNS... can you elaborate?

Sure I can.

Let's say I have an internal FQDN (based on subdomain) that never goes outside and also is never reachable from outside but needs an wildcard LE certificate and hosts are different when I deploy. It would be nice if dynamicdns could add the record for the fqdn as it can exist ofcourse as the container runs in that specific Public IP but isolated; then removes the same recordd after the wildcard for that internal subdomain has be provisioned by ACME.

With the DNS challenge, you don't need any DNS records set. And it's the only way to get a wildcard cert through LE anyway. Have you tried using the DNS challenge? (And then you don't need to remove the A/AAAA records.)
