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.
Universal Container Runtime (UCR)
By default the Jenkins for DC/OS service uses the Universal Container Runtime (UCR).
Previous version of the Jenkins for DC/OS service used the Docker Engine as its default containerizer for both the Jenkins Master and the Agents. Users are recommended to use this runtime if they intend to ugprade from existing installations of the Jenkins service.
The Jenkins for DC/OS service starting with DC/OS 2.0 supports multi-tenancy. Users should familiarize themselves with Quota and Resource Managment Primitives in DC/OS. In particular, service-accounts in a quota enforced group must be given the correct role permissions for the service to launch and perform its operations.
