Overview

The Gitlab Get Diff of Merge pre-built consists of an Operations Manager automation which can be used to get the diff (difference) between the current state and the proposed changes of your gitlab project branch.

The Gitlab Get Diff of Merge workflow serves as an entry point for Operations Manager automation to run the use cases described above.

Supported IAP Versions

Itential pre-builts are built and tested on particular versions of IAP. In addition, pre-builts that work with devices are often dependent on certain orchestration systems (e.g. NSO and IAG). As such, these pre-builts will have dependencies on these other systems. This version of the Gitlab get diff of merge from Repo pre-built has been tested with:

• IAP 2023.1.x

Getting Started

These instructions will help you get a copy of the pre-built in your IAP instance for testing in your environment. Reading this section is also helpful for deployments as it provides you with pertinent information on prerequisites and capabilities.

• The Pre-Built can be installed from within App-Admin_Essential. Simply search for the name of your desired Pre-Built and click the install button (as shown below).

Testing

While Itential tests this pre-built and its capabilities, it is often the case the customer environments offer their own unique circumstances. Therefore, it is our recommendation that you deploy this pre-built into a development/testing environment in which you can test the pre-built.

Using this Pre-Built

The main requirements to use this Pre-built are: 1. Running instance of the Itential OpenSource adapter-gitlab, which can be found in adapter-gitlab

The pre-built can be run using Operations Manager automation Gitlab Get Diff of Merge Automation. Use the following steps to complete the form:

1. Select the appropriate adapter-gitlab instance from the dropdown.
2. Input the Project ID of the project.
3. Input the Merge Request ID.
4. Select either verbose or non-verbose option for the performed operation details.

Note: All fields are mandatory.

Input Schema

Example input formData:

{
  "formData": {
    "mergeRequestId": 10,
    "options": {
      "verbose": false
    },
    "gitLabAdapterName": "gitlab",
    "projectId": "3434"
  }
}

The following table details the property keys of the input object.
