Failed to create docker image exception (Docker Slaves plugin)

[Hugo]

Hello, I am experiencing an error while trying to use the docker slaves plugin. I set up the jenkins job in the following way:

So the job should clone the github repo (which contains the Dockerfile) and build the image, but when I press the build now option the following error shows up:

$ docker volume create

I have been trying to debug it but ran into a dead end. Can anyone offer some advice?

Hi,

this is a know bug, see discussion here: https://groups.google.com/forum/#!topic/jenkinsci-users/k14ZkFV69CA

In global config,  you need to remove the final slash from

jenkins/agent/

Hello, Thanks for the fast answer. But this doesn't seem to be the issue. I tried removing the "/" from the jenkins/agent/ but it keeps giving the same error. What I don't understand is why it is trying to create the container without even building the image. Because it doesn't seem to be cloning the repo where the Dockerfile is. I had already tried this plugin before with the same repo and it was working correctly, but now that I am redoing everything I did last time it is showing this error. Any idea why?

use "jenkins/slave" that was the one that finally worked for me.
