Ontrack CLI Jenkins Pipeline Library

Jenkins pipeline library using the Ontrack GraphQL API.

Installation

JCasC

JCasC (Jenkins Configuration as Code) is the recommended approach:

globalLibraries:
  libraries:
    - name: "ontrack-jenkins-cli-pipeline"
      retriever:
        modernSCM:
          scm:
            github:
              configuredByUrl: true
              credentialsId: "<GitHub credentials>"
              repositoryUrl: "https://github.com/nemerosa/ontrack-jenkins-cli-pipeline"

UI

You can also use the Jenkins management UI to register this library:

Setup

The steps provided by this library, in order to avoid redundant configuration, rely on predefined environment variables and credentials.

Those environment variables and credentials are not strictly required but they will ease the use of the Ontrack steps.

In most of the cases, you just need to define:

• ONTRACK_URL - URL to Ontrack
• ONTRACK_TOKEN - secret text credentials entry containing the authentication token used to connect to Ontrack

See ontrackCliSetup for more information.

Usage

In your Jenkinsfile, declare the version of the pipeline library you want to use and start using the steps provided by the library. For example:

@Library("ontrack-jenkins-cli-pipeline@main") _

pipeline {
    agent any
    stages {
        stage("Setup") {
            steps {
                // Ontrack connection & branch setup
                ontrackCliSetup()
            }
        }
        stage("Preparation") {
            steps {
                // Computing a version in VERSION
                // Ontrack build entry creation
                ontrackCliBuild(release: env.VERSION)
            }
            post {
                always {
                    // Validation run, including detection of the 
                    // status and run information
                    ontrackCliValidate(stamp: 'STAMP')
                }
            }
        }
    }
}

Logging

Most of the steps accept a logging parameter but logging can be configured globally using the ONTRACK_LOGGING environment variable, set to false or true (false is the default).

Note that any logging parameter on the step will override the global settings.

Typically, the ONTRACK_LOGGING environment variable would be set at pipeline level:

pipeline {
    environment {
        ONTRACK_LOGGING = true
    }
}

Versioning

In this example, we use the main branch of the pipeline library but it's better to stick to:

• versioned branches, like v1
• or explicit tags in order to ensure build reproducibility. See the list of available tags in GitHub.

Steps

General setup

• ontrackCliSetup - general purpose setup task to set up Ontrack in your pipeline, from creating common environment variables to initializing project and branch in Ontrack for your pipeline.
• ontrackCliSetupSonarQube - setup of SonarQube properties at project level

Creating Ontrack items

• ontrackCliBuild - creates an Ontrack build entry based on current information
• ontrackCliPromote - creates an Ontrack promotion run for the current build, based on current information or provided information
• ontrackCliValidate - creates an Ontrack validation run for the current build, based on current information or provided information
• ontrackCliValidateTests - creates an Ontrack validation run based on JUnit test results
• ontrackCliValidateWithTestResults - same as above but reuses existing JUnit tst results
• ontrackCliValidateCHML - creates an Ontrack validation run based on critical/high/medium/low stats
• ontrackCliValidatePercentage - creates an Ontrack validation run based on a percentage
• ontrackCliValidateMetrics - creates an Ontrack validation run based on a map of metrics

Setting properties on builds

• ontrackCliBuildMessage - setting a message property on an existing build
• ontrackCliBuildMetaInfo - setting or updating a meta-info property on an existing build
• `ontrackCliBuildGitCommit - setting or updating the "Git commit" property on an existing build

Build links

• ontrackCliBuildLink - creates a link to another build
• ontrackCliBuildLinks - creates several link other builds

Accessing Ontrack information

• ontrackCliLastBranch - getting the last branch for given pattern
• ontrackCliLastPromotion - getting the last build for a given promotion
• ontrackCliLastPromotionByProject - getting the last build for a given promotion over all branches
• ontrackCliGetBuildByVersion - getting a build using its release/label/version property
• ontrackCliGetBuildByMetaVersion - getting a build using a version stored in its meta information
• ontrackCliGetBuildByProjectAndVersion - getting a build using its release/label/version property inside a project
• ontrackCliGetBuildByCommit - getting a build in the current branch using its commit

Auto versioning setup

• ontrackCliAutoVersioning - setting up the auto versioning for the branch
• ontrackCliAutoVersioningProject - setting up the auto versioning rules at project level
• ontrackCliAutoVersioningCheck - checking the auto versioning alignment and creating a corresponding validation

Setup of notifications

• ontrackCliSetupProjectNotifications - setup of notifications at project level
• ontrackCliSetupBranchNotifications - setup of notifications at branch level
• ontrackCliSetupPromotionLevelNotifications - setup of notifications at promotion level
• ontrackCliSetupValidationStampNotifications - setup of notifications at validation stamp level

Generic steps

• ontrackCliGraphQL - performs a GraphQL call to Ontrack and returns the JSON response

Orchestration steps

These steps are very specific in the kind of scenario they are running and interact with more than Ontrack.

• ontrackCliCheckoutConditionalOnPromotionAndTrigger - performs a SCM checkout based on the nature of the trigger

CLI steps

Those steps allow to download and the setup the Ontrack CLI.

• ontrackCliDownload - downloads the Ontrack CLI and sets it into the path
• ontrackCliConnect - creates a connection configuration for the Ontrack CLI, based on provided information or the environment

Ignoring errors

You can run the Ontrack steps in a mode where any error is ignored.

Note that steps returning values will then return a null or empty value. This may cause some issues in some pipelines relying on these values, so it's not a perfect solution.

Set the ONTRACK_IGNORE_ERRORS global environment variable to true.

Failsafe

In case you want to utterly disable all the Ontrack steps, in all pipelines, to do something and in particular, you want to remove any connection to the Ontrack server, you can set the ONTRACK_STOP global environment variable to true.

Like when ignoring errors, the steps returning values will return a null or empty value. This may cause some issues in some pipelines relying on these values, so it's not a perfect solution.
