.. _lf-global-jjb-release: Self-Serve Release Jobs ======================= Self-serve release jobs allow project committers to promote a jar file, container image, Python package or PackageCloud artifact from a staging area to a release area. A release yaml file controls the process, and Jenkins promotes the artifact when a project committer merges the release yaml file in Gerrit. To use the self-release process, create a releases/ or .releases/ directory at the root of the project repository, add one release yaml file to it, and submit a change set with that release yaml file. The required contents of the release yaml file are different for each release, see the schemas and examples shown below. The version string in the release yaml file should be a valid Semantic Versioning (SemVer) string, matching the pattern "#.#.#" where "#" is one or more digits. A version string matching the pattern "v#.#.#" is also accepted. Upon merge of the change, a Jenkins job promotes the artifact and pushes a gpg-signed tag to the repository. .. note:: The release file regex is: (releases\/.*\.yaml|\.releases\/.*\.yaml). In words, the directory name can be ".releases" or "releases"; the file name can be anything with suffix ".yaml". Some release jobs require a specific prefix on the file, as described below. The build node for all release jobs must be CentOS, which supports the sigul client for accessing a signing server to sign a tag. The build node for container release jobs must have Docker installed. A Jenkins admin user can also trigger a release job via the "Build with parameters" action, removing the need to create and merge a release yaml file. The user must enter parameters in the same way as a release yaml file, except for the special USE_RELEASE_FILE and DRY_RUN check boxes. The user must uncheck the USE_RELEASE_FILE check box if the job should run without a release file, instead passing the required information as build parameters. The user can check the DRY_RUN check box to test the job while skipping upload of files to the release repository. For example, the parameters for a Maven release are as follows:: GERRIT_BRANCH = master VERSION = 1.0.0 LOG_DIR = example-project-maven-stage-master/17/ DISTRIBUTION_TYPE = maven USE_RELEASE_FILE = false DRY_RUN = false It's recommended to use Semantic Versions (SemVer) for releases. Refer to https://semver.org for more details on SemVer. For projects that do not follow SemVer can use a build parameter (OVERRIDE_SEMVER_REGEX) with the release job. This build param overrides the default SemVer regex.

LFID ~~~~ Create an ``lfid`` and an ``ssh-key`` ``YOUR_RELEASE_USERNAME`` for example: onap-release ``YOUR_RELEASE_EMAIL`` for example: collab-it+onap-release@linuxfoundation.org ssh-key example: .. code-block:: bash ssh-keygen -t rsa -C "collab-it+odl-release@linuxfoundation.org" -f /tmp/odl-release `Create an LFID with the above values `_ Nexus ~~~~~ Create a Nexus account called ``'jenkins-release'`` with promote privileges. .. image:: ../_static/nexus-promote-privs.png Gerrit ~~~~~~ Log into your Gerrit with ``YOUR_RELEASE_USERNAME``, upload the public part of the ``ssh-key`` you created earlier. Log out of Gerrit and log in again with your normal account for the next steps. In Gerrit create a new group called ``self-serve-release`` and give it direct push rights via ``All-Projects`` Add ``YOUR_RELEASE_USERNAME`` to group ``self-serve-release`` and group ``Non-Interactive Users`` In All project, grant group self-serve-release the following: .. code-block:: none [access "refs/heads/*"] push = group self-serve-release [access "refs/tags/*"] createTag = group self-serve-release createSignedTag = group self-serve-release forgeCommitter = group self-serve-release push = group self-serve-release Jenkins ~~~~~~~ Add a global credential to Jenkins called ``jenkins-release`` and set the ID: ``'jenkins-release'`` as its value insert the private half of the ``ssh-key`` that you created for your Gerrit user. Add Global variables in Jenkins: Jenkins configure -> Global properties -> Environment variables:: RELEASE_USERNAME = YOUR_RELEASE_USERNAME RELEASE_EMAIL = YOUR_RELEASE_EMAIL .. note:: Add these variables to your global-vars-$SILO.sh file or they will be overwritten. Jenkins configure -> Managed Files -> Add a New Config -> Custom File .. code-block:: none id: signing-pubkey Name: SIGNING_PUBKEY (optional) Comment: SIGNING_PUBKEY (optional) Content: (Ask Andy for the public signing key) -----BEGIN PGP PUBLIC KEY BLOCK----- Add or edit the managed file in Jenkins called ``lftoolsini``, appending a nexus section: Jenkins Settings -> Managed files -> Add (or edit) -> Custom file .. code-block:: none [nexus.example.com] username=jenkins-release password= Ci-management ~~~~~~~~~~~~~ Upgrade your project's global-jjb if needed, then add the following to your global defaults file (e.g., jjb/defaults.yaml). .. code-block:: none jenkins-ssh-release-credential: jenkins-release
