The cool thing is that you can also configure this from code as well 🙂
One example is:
https://clear.ml/docs/latest/docs/references/sdk/task#taskinit
Task.init(...,output_uri="<URL_TO_BUCKET>")

You can configure it in ~/clearml.conf at api.files_server

Yea, that I knew 😄 But somehow I didn't think about the clearml.conf

Thank you very much for the quick answer. Still so confusing to me that so many things are configured client side 😄
