create a new task from app.clearml by pulling a repo from github. do i need to make changes (add the clearml 2 line code) in the entrypoint file in the repo for the task to execute in clearml dashboard.

Can your re-explain/re-word this ? What exactly are you trying to do and what exactly did you do ??

i am trying to place the clearml-agent in a docker container and run it in docker mode.

If you are running the clearml-agent in docker, I don't think that is compatible with "docker mode". What do you mean by running in "docker mode" ? What command did you use to start the clearml-agent inside the container ?
