A simple Docker image for running a Jenkins agent alongside its very own Docker daemon. This is useful if you're trying to run Jenkins agents on a Mesos cluster, and you also want to build and push Docker images using your CI system.
For full documentation on how to use this Docker image, please refer to https://docs.mesosphere.com/latest/usage/service-guides/jenkins/.
Try it out locally by running the following command:
docker run --privileged mesosphere/jenkins-dind:0.5.0-alpine \
wrapper.sh "java -version && docker run hello-world"
You'll need to configure the Mesos plugin on your Jenkins master to use this
image. You'll probably also want to give it a special slave label, so that you
don't unnecessarily run builds using the dind image. A relevant snippet of the
Mesos plugin within the Jenkins master's config.xml
follows:
<org.jenkinsci.plugins.mesos.MesosSlaveInfo>
<slaveCpus>0.1</slaveCpus>
<slaveMem>512</slaveMem>
