Feature Request

I am looking for a way to gracefully reload the ssl certificate of a restify server.

Use Case

SSl certificates expire and need renewals from time to time. This can easily be automated with acme.sh/certbot, but node-restify does not pick up the new certificate.

I presume this is on purpose to keep out some side effects, but i would still like this feature for my own service.
I have made a simple snippet that allows watching for file changes on the certificate, but just .close()'ing the service and then running .listen again does not seem to have the wanted effect. The cert only gets recreated when restify.createServer is called, but then all routes have to be re-initted which is not easily possible and mean i would just have to restart the whole application

Example API

for example a server.updateSettings(), or similar call?

Are you willing and able to implement this?

Yes, but it probably won't look as good, so i hope there's a workaround for now.

Start by tracing how restify.createServer, server.close(), and server.listen() handle the SSL certificate, using the reported acme.sh/certbot renewal flow as the reproduction context. The request needs an API decision, such as server.updateSettings(), that reloads the certificate without reinitializing routes or restarting the application; no test or source file is named.
