The way I understand it:

• if you’re executing tasks locally (e.g. on your laptop) then you need this setting because the clearml package needs to know where to upload artifacts (artifacts aren’t proxied through the clearml-server they are rather uploaded directly to the storage of your choice)
• if you’re executing code using ClearML agent, then you can configure agent the way I wrote earlier, and it will use your MinIO instance for uploading artifacts for all of the tasks it executes
