Traefik and gRPC for Temporal at home
Temporal Networking Woes Someday I will potentially write up some stuff about temporal but for now it’s a workflow orchestrator that I’m interested in and I wanted to PoC it in my homelab by replacing a simple cron job to build my blog with a temporal workflow and activity. I was IMMEDIATELY thwarted by a networking error that feels crazy to me but maybe won’t be to others… so enjoy the problem and if you’re here from a Google search, I hope it’s helpful. Getting started with Temporal I wanted to have the server and associated components on my server, but I expected to be running workflows and workers on another computer. For most of my apps I slap some Traefik labels on and we’re good to go. But I got a wild set of errors trying to run a worker on my desktop and connect it to the temporal server on my server over https…. it ended up being because I needed to setup a special protocol in traefik for the reverse proxy to appropriately proxy the grpc call.
