Configuring a Pipeline from a Shared Library

Setting up the pipeline job

The job itself is defined via the usual way of creating a new pipeline job. It is important to make sure that the resulting job uses parameters by checking the This project is parameterized box.

Parameterized Pipeline

Defining parameters

Successively add the following string parameters.

Adding parameters

The parameters in this first set are specific to the individual execution of the pipeline and get passed by the ISPW Webhook.

Name Description
ISPW_Stream ISPW Stream Name
ISPW_Application ISPW Application
ISPW_Release ISPW Release Name
ISPW_Assignment ISPW Assignment Name
ISPW_Src_Level ISPW Level the promote has been started from
ISPW_Owner ISPW Owner User ID

Executing a Shared Library script

To tell Jenkins to execute a pipeline from a shared library, you need to add code like the following to the Pipeline script definition:

Pipeline from Shared Library

Note

Alternatively, you may place the code below in a separate .jenkinsfile and load this from a Git repository.

The example uses

@Library('RNU_Shared_Lib@JenkinsFTS') _

Mainframe_CI_Pipeline_from_Shared_Lib(
    ispwStream:        ISPW_Stream,                             
    ispwApplication:   ISPW_Application,
    ispwRelease:       ISPW_Release,
    ispwAssignment:    ISPW_Assignment,
    ispwSrcLevel:      ISPW_Src_Level,
    ispwOwner:         ISPW_Owner,
    cesToken:          'xxxx',            
    jenkinsCesToken:   'xxxx',
    hciConnectionId:   'xxxx',
    hciToken:          'xxxx',
    ccRepository:      'xxxx',
    gitProject:        'xxxx',
    gitCredentials:    'xxxx'
)    )

where

  • @Library('RNU_Shared_Lib@JenkinsFTS') _ refers to the name of a Shared Library, with @JenkinsFTS in this example referring to the JenkinsFTS branch of the underlying Git repository. The trailing _ is required by Jenkins.
  • Mainframe_CI_Pipeline_from_Shared_Lib refers to the name of the .groovy file in the vars folder of the GitHub repository, containing the pipeline code
  • Within the brackets (...) parameters are passed to the pipeline script. Mainframe_CI_Pipeline_from_Shared_Lib expects a groovy Map (opens new window), containing the following key:value pairs.

The parameters in this first set are specific to the individual execution of the pipeline. They correspond to the parameters defined in the pipeline configuration above and take the values from these pipeline parameters.

Key Value Description
ispwStream ISPW_Stream The ISPW_Stream parameter from the pipeline configuration above
ispwApplication ISPW_Application The ISPW_Application parameter from the pipeline configuration above
ispwRelease ISPW_Release The ISPW_Release parameter from the pipeline configuration above
ispwAssignment ISPW_Assignment The ISPW_Assignment parameter from the pipeline configuration above
ispwSrcLevel ISPW_Src_Level The ISPW_Src_Level parameter from the pipeline configuration above
ispwOwner ISPW_Owner The ISPW_Owner parameter from the pipeline configuration above

The second set of parameters may be specific to individual jobs/pipelines using the same set of scripts. They reference tokens and other IDs that have been defined during the Jenkins configuration phase. To determine the appropriate values to use, refer to the description of the pipeline parameters.

Note

These parameters may be installation specific instead of specific to an individual job/pipeline definition. In that case, they also could be placed in a configuration file.

Key Description
cesToken CES Personal Access Token
jenkinsCesToken Jenkins Credentials ID for the CES Personal Access Token
hciConnectionId HCI Connection ID configured in the Compuware Common Configuration Plugin
hciToken The ID of the Jenkins Credential for the TSO ID that will used to execute the pipeline
ccRepository The Compuware Xpediter Code Coverage Repository that the Pipeline will use
gitProject Github project/user used to store the Topaz for Total Test Projects
gitCredentials Jenkins credentials for logging into git
