Running Docker in Jenkins

[Nuno Santos]

Hi.

I am trying to set up Docker to run in my Jenkins instance.

I have specified the binaries in the Manage Jenkins page. 

I've also installed one of Cloudbee's plugins, to fetch images from docker hub.

However, every time I try to kickstart a build, e.g. in a slave, I get the following error:

I am not sure what I am missing here and haven't been able to find anything in the Internet for this issue.

Thanks in advance for your help.
