Is there any definitive site that shows how to get a production ready instance of Dagster going on a standalone EC2 instance? The Dagster docs are all over the place and not very great for getting an instance setup unless you want to spend a few hours searching for info.

Nothing EC2 specific, but we have guides on how / what services to deploy to get up and running; https://docs.dagster.io/deployment/overview

Yeah, that information is pretty scattered and not complete one bit unfortunately. Have been in the process of setting this up for 2 days due to info either missing or being somewhat strewn throughout the docs.
