here a small preview of what I am working with at the moment.
Everything is still in beta so technically everything can change in future.
I am working mainly on 2 fronts:
1) allow in-container compilation.
This should help to isolate concurrent build from the network point of
view(no ports clashing) and using iptables from the network altogether(no
risks of spontaneous clusters formation or any related problem). On top of
that switching from one version to another of jdk should be easier since
the complexity of configuring them is hidden inside the containers and no
longer handled an the main host level.
2) Using Docker containers to provide dedicate instances of external
With Docker I can start an instance of Mongo or Couch, that lives in it's
own ip address and that is tied to a specific build job and automatically
disposed at the end of the job. Again, the complexity of the configuration
lives inside the containers, so once that is done the solution is easily
reusable by every devloper, without asking him to manually download and
configure the application.
At jenkins level at the moment I am running invocations similar to this:
IP_DOCKER_HOST=$(ip -f inet -o addr show docker0 | cut -d ' ' -f 7 | cut
-d '/' -f 1) \
MVN_M2_CONTAINER="/root/.m2" ; \
docker run -v "$PRJ_FOLDER_HOST":"$PRJ_FOLDER_CONTAINER" \
-v "$MVN_M2_HOST":"$MVN_M2_CONTAINER" \
-w "$PRJ_FOLDER_CONTAINER" \
--privileged openjdk7_maven:iptables \
clean verify -s $MVN_M2_CONTAINER/settings-search-release.xml
-DskipTests=false -Dcheckstyle.skip=true -DskipDocs=true -DuseDocker=true
That is a little scary but most ov it is just configuration to share
folders from the host to the container.
See also a couple of screenshots that show how I can have 5 concurrent
running job, building OGM, each one starting its own private disposable
instance of Couch and Mongo.
I am right now working on Gradle based build to see if they can also fit
well within this approach.

Thanks for your reply. The thing is that these jobs used to work until
recently, so I'm wondering which change could be causing the problem. Maybe
a recent update to Jenkins or one of the plug-ins?
Unfortunately we don't have the config audit plug-in anymore which
provides a history at least of changes to job configs. @Davide, I think I
had installed it once but I guess it got lost when rebuilding the instance
via Puppet? Any chance you could add this plug-in permanently?
@Paolo: Would be very interested to learn more about the Docker stuff
you're working on once you got something :)
