Hi all is there a way to implement authentication and RBAC on top or within dagster? I know that the cloud version has already has, but I was wondering if it's doable with the OS version.

Hello - Dagster doesn't currently have an RBAC feature in the open source product. Depending on where you're deploying Dagster, you can likely add authentication in front of the ingress to your Dagit that prevents users without credentials from accessing the Dagster UI. There are some examples from the community here of how to do that: https://github.com/dagster-io/dagster/issues/2219
