Run your continuous integration, automated testing, and continuous delivery jobs at scale with Jenkins for DC/OS. Instead of the static partitions so typical of other Jenkins clusters, Jenkins for DC/OS can create and destroy agents as demand increases and decreases. With multiple Jenkins masters sharing a single pool of compute resources, you can achieve much more efficient and resilient automations.
Jenkins for DC/OS runs as a root Marathon application inside a Docker container. The default Docker image contains several Jenkins plugins to get you up and running quickly. You can customize the Docker image to match your specific use case.
The Docker container also contains an NGINX reverse proxy that rewrites the URIs into the absolute paths Jenkins requires.
Jenkins for DC/OS needs a directory on disk to store its configuration and build data. To get up and running quickly, you can pin it to a single agent and use this to store the data. However, should the agent go down, your data will be lost.
Before going into production, you should set up a single POSIX-compliant file system that each agent mounts using the same path. Some options include NFS, Ceph, HDFS, and iSCSI.

Scripting and templating your jobs
Over a period of time, the creation and maintenance of hundreds of Jenkins jobs can become a burden. The Job DSL plugin allows for jobs to be scripted and templated, allowing entire pipelines to be defined within code rather than manually. In addition, once pipelines are defined in code, you can backup and version control your job configurations.…Read More
Customizing your Docker container
By default, Mesosphere DC/OS runs everything inside Docker containers to minimize dependencies on the underlying host operating system and to offer resilience in the event of a machine failure. When using Jenkins for DC/OS, the underlying Mesos scheduler in DC/OS creates new Jenkins agents that run as Mesos tasks within a Docker container. User-configured builds are then run inside the same container.…Read More
