If docker is not installed in the master executor, Jenkins doesn't try to run docker on other executors.

I run Jenkins from a docker image, and of course I don't have docker in that image. I've limited the below job to run only on executors that have docker installed. I've also configured the plugin globally to fetch the latest docker.

However, I still get the below error:
