Azure DevOps Tasks (#adftools)

This extension to Azure DevOps has three tasks and only one goal: deploy Azure Data Factory (v2) seamlessly and reliable at minimum efforts. As opposed to ARM template publishing from 'adf_publish' branch, this task publishes ADF directly from JSON files, who represent all ADF artefacts.
The task based on the PowerShell module azure.datafactory.tools available through PSGallery.
Fully written in PowerShell, compatible with Windows PowerShell 5.1, PowerShell Core 6.0 and above.

Three tasks

• Build Azure Data Factory code - Validates all JSON files of ADF (v2) (adftools)
• Publish Azure Data Factory - Deploys entire ADF (v2) from JSON files to ADF instance
• Test connection of ADF Linked Service - Runs test connection of Linked Service of ADF (v2)

Bear in mind that these tasks works only for Azure Data Factory v2.

How to add task

For classic pipelines, you will find the Tasks available under the Deploy tab, or search for adftools:

You can also use the tasks in a pipeline configured with a yml file, the three tasks are called SQLPlayer.DataFactoryTools.BuildADF.BuildADFTask, SQLPlayer.DataFactoryTools.PublishADF.PublishADFTask and SQLPlayer.DataFactoryTools.TestADFLS.TestAdfLinkedServiceTask. You can also use the DevOps UI to configure these tasks and then view the generated yml, to ensure the yml is correct. One example, in which we use the 'Build ADF' task:

- job: 'build_adf'
  displayName: 'Build Azure Data Factory'
  pool:
    vmImage: 'windows-latest'
  steps:
    - task: SQLPlayer.DataFactoryTools.BuildADF.BuildADFTask@1
      displayName: 'Validate ADF files'
      inputs:
        DataFactoryCodePath: '$(System.DefaultWorkingDirectory)/data-factory'
        Action: Build

Publish Azure Data Factory

Use this task to deploy a folder of ADF objects from your repo to target Azure Data Factory instance.
For YAML pipelines, use task PublishADFTask@1.

Key capabilities

• Creation of Azure Data Factory, if not exist (option)
• Deployment of all type of objects: pipelines, datasets, linked services, data flows, triggers, integration runtimes, credentials
• Copes with dependencies (multiple levels) between objects when deploying (no more worrying about object names)
• Build-in mechanism to replace the properties with the indicated values (CSV or JSON file)
• Update, add or remove any property of ADF artefact
• Selective deployment declared in-line or by pointed file
• Stop/start triggers (option)
• Dropping objects when not exist in the source (code) (option)
• Filtering (include or exclude) objects to be deployed by name and/or type and/or type
• Filtering supports wildcards
• Publish options allow you to control:
  • Whether stop and restarting triggers
  • Whether delete or not objects not in the source
  • Whether create or not a new instance of ADF if it not exist
• Tokenisation in config file allows replace any value by Environment Variable or Variable from DevOps Pipeline
• Global Parameters
• Export ARM Templates from JSON files (new!)
• Support for Managed VNET and Managed Private Endpoint (new!)
• ⭐️ Incremental deployment (NEW!)
• Build function to support validation of files, dependencies and config
• Test connections (Linked Services)

For more details, please go to documentation of azure.datafactory.tools.

Parameters

Environment (stage)

Optional parameter. When defined, process will replace all properties defined in (csv) configuration file. The parameter can be either full path to csv file (must ends with .csv) or just stage name. When you provide parameter value 'UAT' the process will try open config file located in .\deployment\config-UAT.csv

More details: Step: Replacing all properties environment-related

Selective deployment

The task allows you to deploy subset of ADF's objects.
You can select objects specifying them by object's type, name or folder which belongs to, using include or exclude option.
All 3 parts (Type, Name, Folder) can be wildcarded, so all such variants are possible:

You can specify them by exact name or wildcard.
Example:

+pipeline.PL_Copy*  
+dataset.ds_srcCopy  
dataset.*  
-pipeline.PL_DoNotPublish*  
-integrationruntime.*
-*.*@testFolder

To simplify user experience – only one field is exposed in order to define include/exclude rules. Therefore, an extra character should be provided before the name/pattern:

• + (plus) - for objects you want to include to a deployment
• - (minus) - for objects you want to exclude from a deployment

If char (+/-) is not provided – an inclusion rule would be applied.

Build/Test Azure Data Factory code

Another very helpful task is Build Azure Data Factory. The task has two actions to be chosen:

Build only

Use this action to validate the code of your Azure Data Factory before you publish it onto target ADF service. The function validates files of ADF in a given location, returning warnings or errors. This validation functionality is implemented in this task, so it is not the same implementation as behind the 'Validate all' button in the ADF UI. The following validation will be performed:

• Reads all files and validates its json format
• Checks whether all dependant objects exist
• Checks whether file name equals object name
• Validate configuration file(s) and its paths

The task sets these 2 pipeline output variables:

• AdfBuildTaskErrors
• AdfBuildTaskWarnings These variables will contain the number of errors or warnings found.

You can use them in any subsequent tasks as any other DevOps variables: $(AdfBuildTaskErrors)

Validate & Export ARM Template

This action uses ADFUtilities NPM package provided by Microsoft. It does exactly the same actions as you can do with ADF UI by clicking Validate all and then Export ARM Template. Therefore, this is a different implementation as the other action described above. So finally, you can automate this step and fully automate ADF deployment, even if you prefer to use Microsoft's approach with ARM Template.

Parameters:

• DataFactoryCodePath - Source folder where all ADF objects are kept. The folder should contain subfolders like pipeline, linkedservice, etc.
• Action - One of two actions to be executed:
  • Build only (simple validate) (Build for in YAML task) - Validates files integrity. No outcome files.
  • Validate & Export ARM Template (Export for in YAML task) - Validates files and export ARM Template files like ADF UI does. ARM Template files as the result. It uses ADFUtilities NPM package provided by Microsoft.

Test connection of ADF Linked Service

After deployment within automated CI/CD process, we would like to test foundamental Linked Services whom are used for dependant objects in ADF. In order to ensure the entire workload works, we must make sure that all Linked Services are configured correctly and have access to pointing resources.
The purpose of this task is to ensure such checking. It works exactly the same as hitting button Check connection in ADF Linked Service.

Be aware that the task uses undocumented API function.
