Thank you. It says in the doco I can use enviromental to control the ID, but I don't understand how -
None

Hi @<1533619716533260288:profile|SmallPigeon24> , I think the worker id is dependent on the worker name, so you can control it this way

Will it work retroavtively, or do I need to create the agent with said name?
And if so, how do I create an agent with a predetermined name?

you configure the worker name in clearml.conf and I think you'll need to re-run it
