Description:

For Docker URL I have entered unix:///var/run/docker.sock based on guesses. (There is no inline help to guide me.) Test Connection reports an error

and if I ignore this and create a project tied to the cloud's label and schedule it, every few seconds I get

Running on Ubuntu 14.04 with Docker installed (docker ps and so on work fine), running various Jenkins versions including 1.566 on Java 7, with the current 0.3.5 plugin.



Is there some trick to making this plugin work with a local connection? What is supposed to be registering the unix URL protocol?
