The mesos-jenkins plugin allows Jenkins to dynamically launch Jenkins slaves on a Mesos cluster depending on the workload!Put simply, whenever the Jenkins Build Queue starts getting bigger, this plugin automatically spins up additional Jenkins slave(s) on Mesos so that jobs can be immediately scheduled! Similarly, when a Jenkins slave is idle for a long time it is automatically shut down.

Usage

To learn more about building and using the plugin please visit the project website.

Changelog

1.0.0 (September 17th 2019)

• Support for Mesos Containerizer

• Suppression of offers when there is no workload in the queue

• Support for Single Use agents

• Support for USER networking

• Enhanced metrics and logging for better observability

• Fixed default long decline timeout to 60s (previously it was incorrectly set to 60k seconds)

• Several bug fixes

NOTE:  Upgrading from previous versions of plugin to 1.0.0 is not backwards compatible due to the addition of support for Mesos containerizer. The plugin configuration needs to be manually fixed after the upgrade for it to work.
