Grpc can manage mTLS for secure tunnel communication. However, if the certificates renew, do I need to reload/restart roadrunner plugin? Is it possible for roadrunner plugin to pick the new certificate dynamically with any need of reload/restart?
I have referred to roadrunner documentations, but nowhere I could see that new certificates would be kicked dynamically. https://roadrunner.dev/docs/app-server-https/2.x/en
Yes, if you renew your certificates, you have to restart RR instance. Here you can find new docs: link
