abapEnvironmentCloneGitRepo

Clones a git repository to a SAP BTP ABAP Environment system

Description

Clones a git repository (Software Component) to a SAP BTP ABAP Environment system. If the repository is already cloned, the step will checkout the configured branch and pull the specified commit, instead. Please provide either of the following options:

• The host and credentials the BTP 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 .pipeline/config.yml file.
In this case, calling the step is essentially reduced to defining the step name.
Calling the step can be done either in an orchestrator specific way (e.g. via a Jenkins library step) or on the command line.

JenkinsCommand Line

abapEnvironmentCloneGitRepo script: this

piper abapEnvironmentCloneGitRepo

Prerequisites

A SAP BTP, 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 BTP, ABAP Environment - Software Component Test Integration (SAP_COM_0510)". This can be done manually through the respective applications on the SAP BTP, 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.

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:
  abapEnvironmentCloneGitRepo:
    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 clone. Also keep in mind that the repositoryName parameter must define a single repository.

Another option is to read the host and credentials from the cloud foundry service key of the respective instance. Furthermore, if you want to clone multiple repositories, they can be specified in a configuration file.

With this approach the config.yml would look like this:

steps:
  abapEnvironmentCloneGitRepo:
    repositories: 'repositories.yml'
    cfCredentialsId: 'cfCredentialsId'
    cfApiEndpoint: 'https://test.server.com'
    cfOrg: 'cfOrg'
    cfSpace: 'cfSpace'
    cfServiceInstance: 'cfServiceInstance'
    cfServiceKeyName: 'cfServiceKeyName'

and the configuration file repositories.yml would look like this:

repositories:
  - name: '/DMO/REPO'
    branch: 'main'
  - name: '/DMO/REPO_COMMIT'
    branch: 'feature'
    commitID: 'cd87a3cac2bc946b7629580e58598c3db56a26f8'
  - name: '/DMO/REPO_TAG'
    branch: 'release'
    tag: 'myTag'

Using such a configuration file is the recommended approach. Please note that you need to use the YAML data structure as in the example above when using the repositories.yml config file. If you want to clone a specific commit, either a commitID or a tag can be specified. If both are specified, the tag will be ignored.

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.

abapEnvironmentCloneGitRepo (
  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.

abapEnvironmentCloneGitRepo (
  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'
)
