ABAP Environment Pipeline

The goal of the ABAP Environment Pipeline is to enable Continuous Integration for the SAP Cloud Platform ABAP Environment, also known as Steampunk. The pipeline contains several stages and supports different scenarios. The general idea is that the user can choose a subset of these stages, which fits her/his use case, for example running nightly ATC checks or building an ABAP AddOn for Steampunk.

!!! note "Scenario: Building ABAP Add-ons for Steampunk" This scenario is intended for SAP Partners, who want to offer a Software as a Service (SaaS) solution on Steampunk. This is currently the only use case for building ABAP Add-ons and, more specifically, the stages "Initial Checks", "Build", "Integration Tests", "Confirm" and "Publish". This scenario will be documented in its own section soon.

The following stages and steps are part of the pipeline:

Stage	Steps
Init	-
Initial Checks	abapAddonAssemblyKitCheckPV, abapAddonAssemblyKitCheckCVs
Prepare System	cloudFoundryCreateService, cloudFoundryCreateServiceKey
Clone Repositories	abapEnvironmentPullGitRepo
ATC	abapEnvironmentRunATCCheck
Build	cloudFoundryCreateServiceKey, abapAddonAssemblyKitReserveNextPackages, abapEnvironmentAssemblePackages, abapAddonAssemblyKitRegisterPackages, abapAddonAssemblyKitReleasePackages, abapAddonAssemblyKitCreateTargetVector, abapAddonAssemblyKitPublishTargetVector
Integration Tests	cloudFoundryCreateService
Confirm	-
Publish	abapAddonAssemblyKitPublishTargetVector
Post	cloudFoundryDeleteService

Below you can find more details about the different stages. Here you can find more information about how to configure your pipeline.

Init

In this stage, the pipeline is initialized. Nothing to see here.

Initial Checks

This stage is executed, if the "Build" stage is configured. It contains checks to verify the validity of the provided AddOn Descriptor.

Prepare System

In this stage, the ABAP Environment system is created. This is done with the cloudFoundryCreateService step.

!!! caution "Limitation" As some parts of the system configuration is done after the Cloud Foundry instance was created, the following workaround is currently necessary: An authorized user has to manually confirm that the ABAP Environment system is ready. This is the case when the email has been received by the initially provided administrator (as configured in the file manifest.yml - as described in configuration). Redefining the "Prepare System" stage via an extension could circumvent the manual confirmation and replace it with an optimistic wait statement - this, however, may lead to a failing pipeline in case the system is not ready in time.

After the confirmation, the Communication Arrangement SAP_COM_0510 (SAP Cloud Platform ABAP Environment - Software Component Test Integration) is created using the step cloudFoundryCreateServiceKey. With the creation of the Communication Arrangement, a User and Password is created on the ABAP Environment system for the APIs that are used in the following stages.

Clone Repositories

As a default we assume that the ABAP Environment system is already configured and all Software Components are cloned and the latest change of the respective Software Components should be pulled with the abapEnvironmentPullGitRepo step. In this stage, the Software Components / Git repositories are then pulled to the ABAP Environment system using the step abapEnvironmentPullGitRepo. The step can receive a list of Software Components / repositories and pulls them successively. If the Software Components have not been cloned on the ABAP Environment system yet or you want to e.g. checkout a different Branch you can make use of the strategy stage parameter and perform other steps and step orders. Please refer to the Configuration section for the abapEnvironment Pipeline or the respective documentations for the abapEnvironmentCheckoutBranch, abapEnvironmentCloneGitRepo and abapEnvironmentPullGitRepo steps.

Either way, if you chose a dedicated strategy or the default Pull variant you can optionally provide a dedicated configuration file, e.g. repositories.yml, containing the repositories to be cloned and the branches to be switched to. This file can be used consistently for all strategies.

ATC

In this stage, ATC checks can be executed using abapEnvironmentRunATCCheck. The step can receive Software Components or packages (configured in YML file - as described in configuration). The results are returned in the checkstlye format. With the use of a pipeline extension, quality gates can be configured (see step documentation or the "Extensions" section in the configuration).

Build

This stage is responsible for building an ABAP AddOn for the SAP Cloud Platform ABAP Environment. The build process of the AddOn is done on a Steampunk system (using SAP_COM_0582) with the help of the ABAP Addon Assembly Kit as a Service (AAKaaS). After executing this stage successfully, the AddOn is ready to be tested.

Integration Tests

This stage is intended to be used for testing the AddOn built in the "Build" stage. Nevertheless, it can be configured seperately. In this stage, another ABAP Environment system is created including the AddOn (if configured correctly).

Confirm

This stage is executed if the stage "Publish" is configured. In this stage a manual confirmation is prompted to confirm the publishing of the AddOn.

Publish

In this stage the AddOn built with this pipeline is published. After that, it is ready to be delivered to productive systems.

Post

At the end of every pipeline (successful or unsuccessful), the system is deprovisioned using the step cloudFoundryDeleteService.
