Nice. Does it read those automatically just like it does from ~/clearml.conf? I don't need to call these environment variables within the Python code?

Fully automatic, just have them defined and Task.init and everything else will work out of the box.
Notice the Env will override clearml.conf, so you can have clearml.conf with other default values inside the container, and have the Env override the definition
(not to worry, it is Not a must to have clearml.conf , it's just a nice way to add default values)
