Can Nginx add upstream dynamically?

Question

Nginx

Greetings comrades.
Tell me, does Nginx or its brother Nginx+ have the ability to add upstream on the fly without restarting the service?
There is a wild need to do this, and judging by the Nginx + documentation, it can only add servers to an already created upstream.

Answer 1

Can not. You need at least a re-reading of the configuration

Answer 2

You can use the consul + consul template bundle, you can throw the address and port of the new upstream into the consul, consul-template sees this, rolls out a new config according to the template and reloads nginx.
