abapEnvironmentCheckoutBranch

Switches between branches of a git repository on a SAP Cloud Platform ABAP Environment system

Description

This step switches between branches of a git repository (Software Component) on a SAP Cloud Platform ABAP Environment system. Please provide either of the following options:

  • The host and credentials the Cloud Platform ABAP Environment system itself. The credentials must be configured for the Communication Scenario SAP_COM_0510.
  • The Cloud Foundry parameters (API endpoint, organization, space), credentials, the service instance for the ABAP service and the service key for the Communication Scenario SAP_COM_0510.
  • Only provide one of those options with the respective credentials. If all values are provided, the direct communication (via host) has priority.

Usage

We recommend to define values of step parameters via config.yml file. In this case, calling the step is reduced to one simple line.
Calling the step can be done either via the Jenkins library step or on the command line.

Command line

piper abapEnvironmentCheckoutBranch

Prerequisites

A SAP Cloud Platform ABAP Environment system is available. On this system, a Communication User, a Communication System and a Communication Arrangement is setup for the Communication Scenario "SAP Cloud Platform ABAP Environment - Software Component Test Integration (SAP_COM_0510)". This can be done manually through the respective applications on the SAP Cloud Platform ABAP Environment System or through creating a service key for the system on cloud foundry with the parameters {"scenario_id": "SAP_COM_0510", "type": "basic"}. In a pipeline, you can do this with the step cloudFoundryCreateServiceKey. In addition, the software component should be cloned into the system instance. You can do this with the step abapEnvironmentPullGitRepo.

Example: Configuration in the config.yml

The recommended way to configure your pipeline is via the config.yml file. In this case, calling the step in the Jenkinsfile is reduced to one line:

abapEnvironmentCheckoutBranch script: this

If you want to provide the host and credentials of the Communication Arrangement directly, the configuration could look as follows:

steps:
  abapEnvironmentCheckoutBranch:
    repositoryName: '/DMO/GIT_REPOSITORY'
    branchName: 'my-demo-branch'
    abapCredentialsId: 'abapCredentialsId'
    host: '1234-abcd-5678-efgh-ijk.abap.eu10.hana.ondemand.com'
Please note that the branchName parameter specifies the target branch you want to switch on. Also keep in mind that the repositoryName parameter must define a single repository.

If you want to read the host and credentials from the cloud foundry service key of the respective instance, the configuration could look as follows:

steps:
  abapEnvironmentCheckoutBranch:
    repositoryName: '/DMO/GIT_REPOSITORY'
    branchName: 'my-demo-branch'
    cfCredentialsId: 'cfCredentialsId'
    cfApiEndpoint: 'https://test.server.com'
    cfOrg: 'cfOrg'
    cfSpace: 'cfSpace'
    cfServiceInstance: 'cfServiceInstance'
    cfServiceKeyName: 'cfServiceKeyName'

Example: Configuration in the Jenkinsfile

It is also possible to call the steps - including all parameters - directly in the Jenkinsfile. In the first example, the host and the credentialsId of the Communication Arrangement are directly provided.

abapEnvironmentCheckoutBranach (
  script: this,
  repositoryName: '/DMO/GIT_REPOSITORY',
  branchName: 'my-demo-branch',
  abapCredentialsId: 'abapCredentialsId',
  host: '1234-abcd-5678-efgh-ijk.abap.eu10.hana.ondemand.com'
)

In the second example, the host and credentialsId will be read from the provided cloud foundry service key of the specified service instance.

abapEnvironmentCheckoutBranch (
  script: this,
  repositoryName: '/DMO/GIT_REPOSITORY',
  branchName: 'my-demo-branch'
  abapCredentialsId: 'cfCredentialsId',
  cfApiEndpoint: 'https://test.server.com',
  cfOrg: 'cfOrg',
  cfSpace: 'cfSpace',
  cfServiceInstance: 'cfServiceInstance',
  cfServiceKeyName: 'cfServiceKeyName'
)
