I was wondering how folks handle admin related stuff in Dagster. How can you make sure that users have access to certain pipelines or repos and not others? How can you admin which resources can be used by which systems/users?

Mostly by not letting users run things directly, we implement that kind of stuff in our own apps that use the Dagit API

Not sure, what exactly your are building. But I would guess you can use git. I am building an application on top of dagster so I would have my own authentication/authorisation layer on top of dagster.
