.. _odl-jenkins: Jenkins ======= The `Release Engineering Project `_ consolidates the Jenkins jobs from project-specific VMs to a single Jenkins server. Each OpenDaylight project has a tab for their jobs on the `jenkins-master`_. The system utilizes `Jenkins Job Builder `_ for the creation and management of the Jenkins jobs. Sections: .. contents:: :depth: 3 :local: New Project Quick Start ----------------------- This section attempts to provide details on how to get going as a new project quickly with minimal steps. The rest of the guide should be read and understood by those who need to create and contribute new job types that is not already covered by the existing job templates provided by OpenDaylight's JJB repo. As a new project you will be mainly interested in getting your jobs to appear in the jenkins-master_ silo and this can be achieved by simply creating a .yaml in the releng/builder project's jjb directory. .. code-block:: bash git clone --recursive https://git.opendaylight.org/gerrit/releng/builder cd builder mkdir jjb/ .. note: releng/global-jjb is a submodule of releng/builder repository which requires a git submodule update --init or using --recursive with git clone. `releng-global-jjb`_ Where should be the same name as your project's git repo in Gerrit. If your project is called "aaa" then create a new jjb/aaa directory. Next we will create .yaml as follows: .. code-block:: yaml --- - project: name: -carbon jobs: - '{project-name}-clm-{stream}' - '{project-name}-integration-{stream}' - '{project-name}-merge-{stream}' - '{project-name}-verify-{stream}-{maven}-{jdks}' project: '' project-name: '' stream: carbon branch: 'master' jdk: openjdk8 jdks: - openjdk8 maven: - mvn33: mvn-version: 'mvn33' mvn-settings: '-settings' mvn-goals: 'clean install -Dmaven.repo.local=/tmp/r -Dorg.ops4j.pax.url.mvn.localRepository=/tmp/r' mvn-opts: '-Xmx1024m -XX:MaxPermSize=256m' dependencies: 'odlparent-merge-{stream},yangtools-merge-{stream},controller-merge-{stream}' email-upstream: '[] [odlparent] [yangtools] [controller]' archive-artifacts: '' - project: name: -sonar jobs: - '{project-name}-sonar' project: '' project-name: '' branch: 'master' mvn-settings: '-settings' mvn-goals: 'clean install -Dmaven.repo.local=/tmp/r -Dorg.ops4j.pax.url.mvn.localRepository=/tmp/r' mvn-opts: '-Xmx1024m -XX:MaxPermSize=256m' Replace all instances of with the name of your project. This will create the jobs with the default job types we recommend for Java projects. If your project is participating in the simultanious-release and ultimately will be included in the final distribution, it is required to add the following job types into the job list for the release you are participating. .. code-block:: yaml - '{project-name}-distribution-check-{stream}' - '{project-name}-validate-autorelease-{stream}' If you'd like to explore the additional tweaking options available please refer to the `Jenkins Job Templates`_ section. Finally we need to push these files to Gerrit for review by the releng/builder team to push your jobs to Jenkins. .. code-block:: bash git add jjb/ git commit -sm "Add jobs to Jenkins" git review This will push the jobs to Gerrit and your jobs will appear in Jenkins once the releng/builder team has reviewed and merged your patch. Jenkins Master -------------- The `jenkins-master`_ is the home for all project's Jenkins jobs. All maintenance and configuration of these jobs must be done via JJB through the `releng-builder-repo`_. Project contributors can no longer edit the Jenkins jobs directly on the server. Build Minions ------------- The Jenkins jobs are run on build minions (executors) which are created on an as-needed basis. If no idle build minions are available a new VM is brought up. This process can take up to 2 minutes. Once the build minion has finished a job, it will be destroyed. Our Jenkins master supports many types of dynamic build minions. If you are creating custom jobs then you will need to have an idea of what type of minions are available. The following are the current minion types and descriptions. Minion Template Names are needed for jobs that take advantage of multiple minions as they must be specifically called out by template name instead of label. Adding New Components to the Minions ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ If your project needs something added to one of the minions, you can help us get things added faster by doing one of the following: * Submit a patch to RelEng/Builder for the appropriate `jenkins-scripts` definition which configure software during minion boot up. * Submit a patch to RelEng/Builder for the `packer/provision` scripts that configures software during minion instance imaging. * Submit a patch to RelEng/Builder for the Packer's templates in the `packer/templates` directory that configures a new instance definition along with changes in `packer/provision`. Going the first route will be faster in the short term as we can inspect the changes and make test modifications in the sandbox to verify that it works. .. note:: The first route may add additional setup time considering this is run every time the minion is booted. The second and third routes, however, is better for the community as a whole as it will allow others to utilize our Packer setups to replicate our systems more closely. It is, however, more time consuming as an image snapshot needs to be created based on the updated Packer definitions before it can be attached to the Jenkins configuration on sandbox for validation testing. In either case, the changes must be validated in the sandbox with tests to make sure that we don't break current jobs and that the new software features are operating as intended. Once this is done the changes will be merged and the updates applied to the RelEng Jenkins production silo. Any changes to files under `releng/builder/packer` will be validated and images would be built triggered by verify-packer and merge-packer jobs. Please note that the combination of a Packer definitions from `vars`, `templates` and the `provision` scripts is what defines a given minion. For instance, a minion may be defined as `centos7-builder` which is a combination of Packer OS image definitions from `vars/centos.json`, Packer template definitions from `templates/builder.json` and spinup scripts from `provision/builder.sh`. This combination provides the full definition of the realized minion. Jenkins starts a minion using the latest image which is built and linked into the Jenkins configuration. Once the base instance is online Jenkins checks out the RelEng/Builder repo on it and executes two scripts. The first is `provision/baseline.sh`, which is a baseline for all of the minions. The second is the specialized script, which handles any system updates, new software installs or extra environment tweaks that don't make sense in a snapshot. Examples could include installing new package or setting up a virtual environment. Its imperative to ensure modifications to these spinup scripts have considered time taken to install the packages, as this could increase the build time for every job which runs on the image. After all of these scripts have executed Jenkins will finally attach the minion as an actual minion and start handling jobs on it. Flavors ^^^^^^^ Performance flavors come with dedicated CPUs and are not shared with other accounts in the cloud so should ensure consistent performance. .. list-table:: Flavors :widths: auto :header-rows: 1 * - Instance Type - CPUs - Memory * - v3-standard-2 - 2 - 8 * - v3-standard-4 - 4 - 16 * - v3-standard-8 - 8 - 32 * - v3-standard-16 - 16 - 64 * - odl-highcpu-2 - 2 - 2 * - odl-highcpu-4 - 4 - 4 * - odl-highcpu-8 - 8 - 8 Pool: ODLVEX ^^^^^^^^^^^^ .. raw:: html
