Attaching a data volume with user id 102 does not work but 1000 does. Update Readme?

Normally I wouldn't want to be on the bleeding edge of jenkins, but I'm trying to use the Docker Plugin to then have dynamic slaves. However, with Docker v1.2.0 I need to have at least jenkins 1.580, but 1.583 is the only tagged version greater than 1.580. (See: jenkinsci/docker-plugin#97)

[mtscout6]

I should mention that if I do not attach the data volume it works fine. When I ran docker run --rm -it jenkins:1.583 /bin/sh and observed the contents of /var/jenkins_home/ it was empty as I'd expect. So, I'm sure the image is not supplying anything to that directory that the volume would override.

You are probably not running the docker container as the same user (-u
) which owns the files in the mounted volume.

From the readme:

First, ensure that /your/home is accessible by the jenkins user in container (jenkins user - uid 102 normally - or use -u root), then:

That is the owner of that volume https://github.com/mtscout6/jenkins-docker/blob/master/jenkins-data/Dockerfile#L5-L7

I should mention that that setup worked fine against 1.565.

[mtscout6]

I finally found the problem. The uid for the jenkins user is not 102 it's 1000

➜  jenkins-docker git:(master) ✗ docker run --rm -it jenkins:1.583 /bin/sh
$ cat /etc/passwd | grep jenkins
jenkins:x:1000:1000::/var/jenkins_home:/bin/bash

Change uid from 102 -> 1000 and worked like a charm: https://github.com/mtscout6/jenkins-docker/blob/master/jenkins-data/Dockerfile#L5

Is this intentional or should docs get updated, or am I misunderstaning what 102 represents on the readme?

I'm running into a similar error. Without volume -v, it works fine. However, when using volume, it hangs in this entry on the log file:

INFO: Winstone Servlet Engine v2.0 running: controlPort=disabled
Nov 03, 2014 2:12:50 AM jenkins.InitReactorRunner$1 onAttained
INFO: Started initialization

Any clues?

[dzuluaga]

Nevermind, it was just slow, after like 5 minutes it finally started. I wonder why though.
