what about this script (replace with your creds, comment out creds in clearml.conf for now)

from clearml import Task
from clearml.storage.helper import StorageHelper

task = Task.init("test", "test")
task.setup_aws_upload(
    bucket="bucket1",
    host="localhost:9000",
    key="",
    secret="",
    profile=None,
    secure=True
)
helper = StorageHelper.get("

")
