I'm trying to spin up the Ruby GRPC component within Nginx/Phusion Passenger. The idea being, since I already do a passenger app reload when deploying my main rails app, adding the GRPC component to it will mean it too would get reloaded on deploys. This would mean I wouldn't have to maintain a systemd file. However, I'm having difficulty getting this to work, and can't find any solid documentation on this. Has anyone been able to do this themselves? Is it even possible, or am I chasing a pipe dream? It seems like doing the Ruby HTTP part can be done using some sort of custom config.ru/rack app, but the grpc seems a bit tricker.
