Make JJB able to configure all aspects of the Jenkins master ------------------------------------------------------------ Key: OVIRT-2039 URL: https://ovirt-jira.atlassian.net/browse/OVIRT-2039 Project: oVirt - virtualization made easy Issue Type: New Feature Components: JJB Reporter: Barak Korren Assignee: infra Labels: upstream-contribution There are two aspects of jenkins that JJB knows how to configure at this time: # Jobs # Views There are however, other important aspects of the Jenkins configuration one typically needs to deal with: # Plugins # Credentials # Global configuration setting such as global environment # Gerrit and GitHub trigger settings # Custom user data It is desirable that JJB would be able to encompass all the required configuration for a given Jenkins instance. We should consider enabling it to configure the setting mentioned above and contribute that work to the upstream JJB project or distribute it as a separate plugin.
