Hi UnevenDolphin73

Maybe. When the container spins, are there any identifiers regarding the task etc available?

You mean at the container level or at clearml?

I create a folder on the bucket per 

python train.py

 so that the environment variables files doesn't get overwritten if two users execute almost-simultaneously

Nice 🙂 I have an idea, how about per user ID? then they can access their "secrets" based on the owner of the Task ?
task.data.user
