Thanks, yes I used this feature and was aware of its existence. Nonetheless, if you check SaturnCloud, their experience is a lot smoother, since the docker container environment is declared as a separate step from cluster declaration. The reason this is relevant is because you generally don’t want to give all users the ability to spin up their own clusters, primarily due to cost and governance considerations. Instead, you want to give users the ability to select among a list of available clusters and then attach the container environment.
