Hello Jan, You are completely right.. If i set the docker image at taskInfo it is running properly. The reason that i wanted to add the docker image as an executor is because i would like to have one task per container. If i setContainer at taskInfo every task is going to run under the same container? Or each task will have its own container? I would like to provide an isolation between docker containers and tasks to my framework.
