I was playing around with the Render Free Tier and trying to deploy a (non-dockerized) Rails app. However, I kept getting 404’s when it deployed, and the logs showed no activity. So I tried the sample Rails app provided in the documentation. I forked it here: GitHub - mdbenjam/rails-6 and just changed the render.yaml to mark the plans as free. I had the same issue with the sample app.
When I upgraded my plan to the starter package, it started working, so I assume it’s just that rails apps can’t run in such a constrained environment?
Just wanted to let folks know, since I spent a good amount of time digging into it.
