For developers, you can refer to http://git-scm.com/docs for its usage. + +Gerrit is used here for facilitating online code reviews for our git version control system. +As a reviewer, you can see the changes are shown in a side-by-side style and add some inline comments. + +Jenkins and JJB +---------------- + +Jenkins is a Continuous Integration system that runs tests and automates some parts of project operations. +Jenkins mainly focuses on building/testing software projects continuously and monitoring +executions of externally-run jobs. Upstream documentation is available at https://jenkins-ci.org/. + +Jenkins supports plugins, which allows to be extended to meet specific requirements. +Numbers of plugins have been installed, and new ones can be installed when requirements arise. + +The Jenkins jobs are defined by Jenkins Job Builder(JJB) in human readable YAML format. +The jobs defined are the key points of CI pipeline. +To make clear how the jobs in pipeline run to complete the build, deploy, test works, +you can refer to https://wiki.opnfv.org/octopus/pipelines. +Moreover, to start your own job in Jenkins, +you can write a JJB under the guide of https://wiki.opnfv.org/octopus/jenkins_wow. + +Artifact Repository +------------------- + +An artifact repository is a collection of binary software artifacts +and metadata stored in a defined directory structure, +it is a kin to what subversion is to source code, i.e., +it is a way of versioning artifacts produced by build systems, CI, and so on. +At this moment, since there is not enough storage space of LF environment, +Google Cloud Storage is used as the OPNFV artifact repository temporarily. + +If you want to further find out what the artifact repository is and how to use OPNFV artifact repository, +the wiki link https://wiki.opnfv.org/octopus/artifact_repository provides a good reference. |
