Nope! You're not alone. This has been an issue in the Rails community for a while. It's why DHH started working on it, which Sam Ruby noticed and moved forward in a really big way. It's still going to be some what challenging for some folks as this Dockerfile makes its way through the community, but this is a really small step in the right direction for improving the Rails deployment story. There's now at least a "de facto standard" for people to build tooling around. Fly.io is going to switch over to the official Rails Dockerfile gem for pre-7.1 apps really soon, so deploying a vanilla rails app will be as simple as `fly launch` and `fly deploy`.
