Description

Jenkins is a continuous integration server that monitors executions of repeated jobs, such as building a software project or jobs run by cron. The Matrix Project is a module which handles creating Jenkins multi-configuration projects (matrix projects). Matrix Authorization allows configuring the lowest level permissions, such as starting new builds,
configuring items, or deleting them, individually.

Python-RSA is a RSA implementation in Python. It can be used as a Python
library as well as the commandline utility.

Ansible is a SSH-based configuration management, deployment, and task execution system. The openshift-ansible packages contain Ansible code and playbooks for installing and upgrading OpenShift Container Platform 3.
