Continuous Integration: Tagging Jenkins Pipeline

gCubeTagging Pipeline Project

In gCube we use a Pipeline to tag all the repositories forming a gCube Release. The pipeline project is available at: https://jenkins.d4science.org/job/Pipeline-gCubeTagging/

Parameters

The pipeline takes as input the parameters needed to locate a commits report.

The commits report is generated by the Builder pipeline. The tagging pipeline assumes that the report is available at:

https://code-repo.d4science.org/gCubeCI/gCubeReleases/raw/branch/master/closed/<gcube_release_version>/build_commits.<report_number>.csv

Triggers

No triggers are defined because the pipeline is expected to be manually launched by the Release Manager:

It can be changed according to the release needs and the availability of a sufficient number of dedicate agents in Jenkins.

Git

The pipeline is maintained in a Git repository. This section connects the project to the Git repository.

Jenkins Pipeline Definition

Git Repository

The definition of the gCube release pipeline is maintained in this Git Repository: https://code-repo.d4science.org/gCubeCI/gCubeTagging.

Requirements on Jenkins

• Jenkins ver. 2.164.2 or newer
• Pipeline Plugin
• Pipeline: Basic Steps
• Pipeline: Maven
• Pipeline: SCM Step plugin ver. 2.7 or newer
• Pipeline: Shared Groovy Libraries ver. 2.15 or newer
• User credentials configured on Jenkins. These are needed to set the author of the tag. git.gcube is currently used

Jenkins Pipeline Execution

In order to use as input the following sample report available at https://code-repo.d4science.org/gCubeCI/gCubeRelease/raw/branch/master/releases/4.10.0/build_commits.12.csv:

GroupID,ArtifactID,Version,SCM URL,Build Number,Distribution URL,Filename,Packaging
org.gcube.tools,strategy-forward,1.1.0,https://code-repo.d4science.org/Playground/MergeStrategyFastForward,66f5fd1da37229615268955eeaf46870dd4d6576,...

We run the pipeline with the following parameters:

• Type = TAG
• gcube_release_number = 4.10.0
• report_number = 12

On the jenkins console, we can see the messages logging the tagging activity on the repository:

On gitea, we can appreciate that the tag has been pushed;

On a local cloned repo, we can fetch the new tag:

Tags

The pipeline must tag the master branch at the commit ID reported in the build report.

The commit is tagged twice:

• v<component version>
• r<Gcube Release number>

Tag Report

If the pipeline execution succeeds, it sends a tag report to the release manager. The report includes the following information for each Git repository tagged:

• the artifact id
• the artifact version
• the SCM url
• the commit tagged
• the component tag pushed to the repository
• the gCube release tag pushed to the repository

Here's an example of a tag report:
