Configuring Jenkins in 5.5.x

Updated on December 13, 2021

If you are using a Run Jenkins step task in your pipeline, configure Jenkins so that it can communicate with the orchestration server.

  1. On the orchestration server, create an authentication profile that uses Jenkins credentials.
    • If you are using a version of Jenkins earlier than 2.17.6, create an authentication profile on the orchestration server that specifies the credentials to use.
      1. Click CreateSecurityAuthentication Profile.
      2. Enter a name, and then click Create and open.
      3. In the User name field, enter Jenkins user ID.
      4. Click Set password, enter the Jenkins password, and then click Submit.
      5. Click the Preemptive authentication check box.
      6. Click Save.
      7. Go to step 4.

        For more information about configuring authentication profiles, see Creating an authentication profile.

    • If you are using Jenkins 2.17.6 or later and want to use an API token for authentication, go to step 2.
    • If you are using Jenkins 2.17.6 or later and want to use a Crumb Issuer for authentication, go to step 3.
  2. If you are using Jenkins version 2.17.6 or later and want to use an API token for authentication, do the following steps:
    1. Log in to the Jenkins server.
    2. Click People, click the user who is running the Jenkins job, and then click ConfigureAPI token.
    3. Generate the API token.
    4. Create an authentication profile on the orchestration server by clicking CreateSecurityAuthentication Profile.
    5. In the User name field, enter the Jenkins user ID.
    6. Click Set password, enter the API token that you generated, and then click Submit.
    7. Click the Preemptive authentication check box.
    8. Click Save.
    9. Go to step 4.

      For more information about configuring authentication profiles, see Creating an authentication profile.

  3. If you are using Jenkins version 2.17.6 or later and want to use a Crumb Issuer for authentication, do the following steps:
    1. Log in to the Jenkins server.
    2. Click Manage JenkinsManage Plugins and select the check box for the Strict Crumb Issuer plug-in.
    3. Click Manage JenkinsConfigure Global Security.
    4. In the CSRF protection section, in the Crumb Issuer list, select Strict Crumb Issuer.
    5. Click Advanced, and then clear the Check the session ID check box.
    6. Click Save.
    7. Create an authentication profile on the orchestration server by clicking CreateSecurityAuthentication Profile.
    8. In the User name field, enter the Jenkins user ID.
    9. Click Set password, enter the Jenkins password, and then click Submit.
    10. Click the Preemptive authentication check box.
    11. Click Save.
    12. Go to step 4.

      For more information about configuring authentication profiles, see Creating an authentication profile.

    The following steps describe one of the ways to configure Jenkins jobs for the integration with Deployment Manager to work (using Jenkins Free Style Project as the option). This can be done in multiple different ways (e.g. with workflow plugin and groovy, or scripts in Ant, Gradle, etc.).
  4. Install the Post build task plug-in.
  5. Install the curl and jq commands on the Jenkins server. As mentioned above, these can be replaced with any other scripts as well.
  6. Create a new freestyle project.
  7. On the General tab, select the This project is parameterized check box.
  8. Add the DeploymentID and CallBackURL parameters.
    1. Click Add parameter, and then select String parameter.
    2. In the String field, enter DeploymentID.
    3. Click Add parameter, and then select String parameter.
    4. In the String field, enter CallBackURL.
  9. To add parameters that you can use in Run Jenkins step tasks in the pipeline, click Add parameter, select String parameter, and enter the string of the parameter. The system automatically populates these values in Jenkins tasks. You can add any of the following strings:
    1. If you are configuring Jenkins tasks in a merge pipeline, add any of the following strings:
      • DeploymentID: Deployment ID of the pipeline on which the task is triggered.
      • DeploymentNumber: Sequence number of the deployment.
      • TaskID: TaskID of the Jenkins task.
      • CallBackURL: URL to post the status of task.
      • OrchestratorURL: URL on which the Jenkins task is configured.
      • PipelineName: Pipeline name on which the Jenkins task is configured.
      • PipelineID: ID of the pipeline on which the Jenkins task is configured.
      • ApplicationName: Application name for which the pipeline is configured.
      • ApplicationVersion: Application version for which the pipeline is configured.
      • RepositoryName: Repository to publish the merged branch.
      • BranchName: Name of the branch for which the merge Jenkins task is configured.
      • BranchFilePath: File path to the branch artifact.
    2. If you are configuring Jenkins tasks in a deployment pipeline, add any of the following strings:
      • DeploymentID: Deployment ID of the pipeline on which the task is triggered.
      • DeploymentNumber: Sequence number of the deployment.
      • TaskID: TaskID of the Jenkins task.
      • CallBackURL: URL to post the status of task.
      • OrchestratorURL: URL on which the Jenkins task is configured.
      • PipelineName: Pipeline name on which the Jenkins task is configured.
      • PipelineID: ID of the pipeline on which the Jenkins task is configured.
      • RepositoryName: Repository to publish the merged branch.

      • ArtifactPath: Full path to the artifact that the Deploy task uses.
      • CurrentStage: Name of the stage on which the Jenkins task is configured.
      • CurrentStageURL: URL of the system on which the Jenkins task is configured.
