Unix socket support

[zuBux]

Hi,

Does the plugin support Unix sockets for connecting to the Docker server? I 've tried adding "unix:///var/run/docker.sock" as a URL but I 'm getting an error, so I assume it hasn't been implemented. There is no reference to Unix sockets in the documentation as well. Maybe it can be added in the feature?

Having the same problem: Using unix:///var/run/docker.sock is documented in docker-java used to communicate with the docker api so it should work if it's passed on transparently.

+1 this option is really important.

Confirmed that javadocker works just fine with unix:///var/run/docker.sock.

Got the development environment set up but couldn't get this plugin to list itself under configuration even though it's listed under installed plugins. Never done Jenkins plugins before but it should be an easy fix...

I was able to accomplish this, but had to do some extra work to make it functional:

• Include a mapping when creating the Jenkins container: -v /var/run/docker.sock:/var/run/docker.sock
• Run container.
• Manually patch the Jenkins container (this feels like a manual hack):
  • docker exec --user root -it jenkins /bin/bash to launch a container root shell.
  • groupadd -g 999 docker Please note the '999' is the group id of the docker group in the hosts' /etc/group file
  • usermod -a -G docker jenkins to place the Jenkins user into the Docker group.
  • I think stopped/started the container at this point to ensure the group became available
• Configure Jenkins Docker URL to be: unix:///var/run/docker.sock

Credit for this goes elsewhere, but I didn't keep the link, unfortunately.
