This may be a smooth brain question but I am trying to practice deploying dagster on AWS. I think ECS hosted on Fargate is probably the way to go. I've looked at the 'Deploying Dagster to Amazon Web Services' guide and cloned the GitHub repo.... It doesn't do a good job of explaining the actual creation of ECS and task definitions. I know the docs are supposed to be specifically for Dagster concepts, but a guide should be more complete in helping a user set this up from start to finish. Am I missing something? Can somebody link to helpful resources or explain these concepts in more detail? I am a complete noob when it comes to AWS. Been trying to learn it for a few weeks now.
