Tools for deploying Data Factory (v2) in Microsoft Azure

azure.datafactory.tools

PowerShell module to help simplify Azure Data Factory CI/CD processes. This module was created to meet the demand for a quick and trouble-free deployment of an Azure Data Factory instance to another environment.
The main advantage of the module is the ability to publish all the Azure Data Factory service code from JSON files by calling one method. The module supports now:

• Creation of Azure Data Factory, if it doesn't exist
• Deployment of all type of objects: pipelines, datasets, linked services, data flows, triggers, integration runtimes
• Finding the right order for deploying objects (no more worrying about object names)
• Built-in mechanism to replace, remove or add the properties with the indicated values (CSV and JSON file formats supported)
• Stopping/starting triggers
• Dropping objects when not exist in the source (code)
• Filtering (include or exclude) objects to be deployed by name and/or type
• 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

The following features coming in the future:

• Build function to support validation of files, dependencies and config
• Unit Tests of selected Pipelines and Linked Services

The module publishes code, which is created and maintained by ADF in a code repository, when configured.

Overview

This module works for Azure Data Factory V2 only and uses Az.DataFactory PowerShell module from Microsoft for the management of objects in ADF service.

Support

The module is compatible and works with Windows PowerShell 5.1, PowerShell Core 6.0 and above. This means you can use Linux-based agents in your Azure DevOps pipelines.

How to start

Install-Module

To install the module, open PowerShell command line window and run the following lines:

Install-Module -Name azure.datafactory.tools -Scope CurrentUser
Import-Module -Name azure.datafactory.tools

If you want to upgrade module from a previous version:

Update-Module -Name azure.datafactory.tools

Check your currently available version of module:

Get-Module -Name azure.datafactory.tools

Publish Azure Data Factory

This module publishes all objects from JSON files stored by ADF in a code repository (collaboration branch). Bear in mind we are talking about master branch, NOT adf_publish branch.
If you want to deploy from adf_publish branch - read this article: Deployment of Azure Data Factory with Azure DevOps.

Where is my code?

If you have never seen code of your Azure Data Factory instance - then you need to configure the code repository for your ADF. This article helps you to do that: Setting up Code Repository for Azure Data Factory v2.
Once you have set up the code repository, clone the repo and pull (download) onto local machine. The folder structure should look like this:

SQLPlayerDemo  
    dataflow  
    dataset  
    integrationRuntime  
    linkedService  
    pipeline  
    trigger  

Some of these folders might not exist when ADF has none of that kind of objects.

Examples

Publish (entire) ADF code into ADF service in Azure:

Publish-AdfV2FromJson 
   -RootFolder            <String>
   -ResourceGroupName     <String>
   -DataFactoryName       <String>
   -Location              <String>
   [-Stage]               <String>
   [-Option]              <AdfPublishOption>
   [-Method]              <String>

Assuming your ADF is named SQLPlayerDemo and the code is located in c:\GitHub\AdfName\, replace the values for SubscriptionName, ResourceGroupName, DataFactoryName and run the following command using PowerShell CLI:

$SubscriptionName = 'Subscription'
Set-AzContext -Subscription $SubscriptionName
$ResourceGroupName = 'rg-devops-factory'
$DataFactoryName = "SQLPlayerDemo"
$Location = "NorthEurope"
$RootFolder = "c:\GitHub\AdfName\"
Publish-AdfV2FromJson -RootFolder "$RootFolder" -ResourceGroupName "$ResourceGroupName" -DataFactoryName "$DataFactoryName" -Location "$Location"

Other environments (stage)

Use optional [-Stage] parameter to prepare json files of ADF with appropriate values for properties and deploy to another environment correctly. See section: How it works / Step: Replacing all properties environment-related for more details.

Detailed Wiki documentation - coming soon.

Publish Options

The options allows you control which objects should be deployed by including or excluding them from the list. First of all you need to create the object:

# Example 0: Creating Publish Option object
$opt = New-AdfPublishOption

AdfPublishOption contains the following options:

• [HashTable] Includes - defines a list of objects to be published (default: empty)
• [HashTable] Excludes - defines a list of objects to be NOT published (default: empty)
• [Boolean] DeleteNotInSource - indicates whether the objects not in the source should be deleted or not (default: false)
• [Boolean] StopStartTriggers - indicates whether the triggers would be stopped and restarted during the deployment (default: true)
• [Boolean] CreateNewInstance - specifies whether the target ADF should be created when it does not exist. When target ADF doesn't exist and this option is set to false then Publish-AdfV2FromJson function fails. (default: true)
• [Boolean] DeployGlobalParams - indicates whether deploy Global Parameters of ADF. Nothing happens when parameters are not defined. (default: true)
• [Boolean] FailsWhenConfigItemNotFound - indicates whether configuration items not found fails the script. (default: true)
• [Boolean] FailsWhenPathNotFound - indicates whether missing paths fails the script. (default: true)

Subsequently, you can define the needed options:

# Example 1: Including objects by type and name pattern
$opt = New-AdfPublishOption
$opt.Includes.Add("pipeline.Copy*", "")
$opt.DeleteNotInSource = $false

# Example 2: Excluding objects by type
$opt = New-AdfPublishOption
$opt.Excludes.Add("linkedService.*", "")
$opt.Excludes.Add("integrationruntime.*", "")
$opt.Excludes.Add("trigger.*", "")
$opt = New-AdfPublishOption

# Example 3: Excluding all objects from deployment
$opt = New-AdfPublishOption
$opt.Excludes.Add("*", "")
$opt.StopStartTriggers = $false

# Example 4: Including only one object to deployment
$opt = New-AdfPublishOption
$opt.Includes.Add("pipeline.Wait1", "")
$opt.StopStartTriggers = $false

# Example 5: Ignore missing configuration items (will just write warning to standard output instead)
$opt = New-AdfPublishOption
$opt.FailsWhenConfigItemNotFound = $false

# Example 5: Ignore missing paths (will just write warning to standard output instead)
$opt = New-AdfPublishOption
$opt.FailsWhenPathNotFound = $false

Bear in mind that Includes and Excludes lists are rules out each other.
Objects would be excluded from deployment only if Includes list remains empty.
When both lists are empty - all objects going to be published.

Includes & Excludes rules in a file

You can define set of filtering rules (includes/excludes) in a file and load all of them when creating Publish Option objects:

# Example 5: Creating Publish Option object with an initialised rules
$opt = New-AdfPublishOption -FilterFilePath ".\deployment\rules.txt"

Because one file contains all rules - there is a way to differentiate Include rules from Exclude.
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.

Filtering file example

+pipeline.*
trigger.*
-*.SharedIR*
-*.LS_SqlServer_DEV19_AW2017

The above file (if used) adds:

• 2 items to Includes list (line 1-2)
• 2 items to Excludes list (line 3-4)

The file should use UTF-8 encoding.

Using Publish Options in deployment

Once you define all necessary options, just add the parameter to the Publish function:

Publish-AdfV2FromJson -RootFolder "$RootFolder" `
   -ResourceGroupName "$ResourceGroupName" `
   -DataFactoryName "$DataFactoryName" `
   -Location "$Location" `
   -Option $opt

Pattern (WildCard)

As you probably noticed, you can use some patterns when defining name or type for objects to be included or excluded to/from deployment. To determine whether an object matches to the pattern (wildcard) - module uses the -like operator, as known in PowerShell. Therefore you can use the following combinations:

trigger.*
dataset.DS_*
*.PL_*
linkedService.???KeyVault*
pipeline.ScdType[123]

Full name of objects supported by the module is built of: {Type}.{Name}
All potential combinations can be found in code repository of ADF:
Type - name of folder
Name - name of file (without JSON extension)

Publishing objects from selected ADF's folder only

Although providing a pattern of selected object names to be published gives great flexibility in terms of part-deployment, it might not cover other scenarios. When your ADF has objects organised in folders, you may want to publish objects only within that folder, no matter what will change in the future.
Let's take the following ADF as an example:

If you want to publish only objects from "Copy" folder(s), you must perform three steps before publishing:

1. Load all ADF objects from your code (local folder)
2. Execute function which returns list of objects located in selected folder in ADF
3. Add returned list (of objects) to Includes in Publish Option

Sounds complicated? You have tools to do all those things!

# Step 1
$adf = Import-AdfFromFolder -RootFolder "$RootFolder" -FactoryName $DataFactoryName

# Step 2
$list1 = $adf.GetObjectsByFolderName('Copy')

# Step 3
$opt = New-AdfPublishOption
$opt.Includes += $list1

# Finally: Run Publish as usual
Publish-AdfV2FromJson -RootFolder "$RootFolder" -ResourceGroupName "$ResourceGroupName" -DataFactoryName "$DataFactoryName" -Location "$Location" -Option $opt

Naturally, you can add more objects from different folder. Just repeat steps 2-3:

$list2 = $adf.GetObjectsByFolderName('JSON')
$opt.Includes += $list2

Remember: Current version will not publish related objects when list of objects would be provided in Includes publish options. You must ensure that all dependent objects are already exist on target ADF service.

Publishing Method

Parameter: Method (optional)
Currently Publish-AdfV2FromJson cmdlet contains two methods of publishing:

• AzDataFactory,
• AzResource (default).

AzResource method has been introduced in version 0.9.0 due to bugs in Az.DataFactory PowerShell module and uses Az.Resources module to deploy Data Factory resources. However, if you still want to use Az.DataFactory module for deployments for any reasons - just use this parameter and specify the first method.

How it works

This section describes what the function Publish-AdfV2FromJson does step by step.

Step: Create ADF (if not exist)

You must have appropriate permission to create new instance.
Location parameter is required for this action.

Step: Replacing all properties environment-related

This step will be executed only when [Stage] parameter has been provided.
The whole concept of CI & CD (Continuous Integration and Continuous Delivery) process is to deploy automatically and without risk onto target infrastructure, supporting multi-environments. Each environment (or stage) has to be exactly the same code except for selected properties. Very often these properties are:

• Data Factory name
• Azure Key Vault URL (endpoint)
• Selected properties of Linked Services
• Some variables
• etc.

All these values are hold among JSON files in the code repository and due to their specifics - they are not parameterised as it happens in ARM template. That's why we need to replace the selected object's parameters into one specified for particular environment. The changes must be done just before deployment.

In order to address those needs, the process is able to read flat configuration file with all required values per environment. Below is an example of such config file:

type,name,path,value
linkedService,LS_AzureKeyVault,typeProperties.baseUrl,"https://kv-blog-uat.vault.azure.net/"
linkedService,LS_BlobSqlPlayer,typeProperties.connectionString,"DefaultEndpointsProtocol=https;AccountName=blobstorageuat;EndpointSuffix=core.windows.net;"
pipeline,PL_CopyMovies,activities[0].outputs[0].parameters.BlobContainer,UAT
pipeline,PL_CopyMovies_with_param,parameters.DstBlobContainer.defaultValue,UAT
pipeline,PL_Wait_Dynamic,parameters.WaitInSec,"{'type': 'int32','defaultValue': 22}"
# This is comment - the line will be omitted

You can replace any property with that method.

There are 4 columns in CSV file:

• type - Type of object. It's the same as folder where the object's file located
• name - Name of objects. It's the same as json file in the folder
• path - Path of the property's value to be replaced within specific json file
• value - Value to be set

Column TYPE

Column type accepts one of the following values only:

• integrationRuntime
• pipeline
• dataset
• dataflow
• linkedService
• trigger
• factory (for Global Parameters)

Column PATH

Unless otherwise stated, mechanism always replace (update) the value for property. Location for those Properties are specified by Path column in Config file.
Additionally, you can remove selected property altogether or create (add) new one. To define the desired action, put character + (plus) or - (minus) just before Property path:

• + (plus) - Add new property with defined value
• - (minus) - Remove existing property

See example below:

type,name,path,value
# As usual - this line only update value for connectionString:
linkedService,BlobSampleData,typeProperties.connectionString,"DefaultEndpointsProtocol=https;AccountName=sqlplayer2019;EndpointSuffix=core.windows.net;"
# MINUS means the desired action is to REMOVE encryptedCredential:
linkedService,BlobSampleData,-typeProperties.encryptedCredential,
# PLUS means the desired action is to ADD new property with associated value:
linkedService,BlobSampleData,+typeProperties.accountKey,"$($Env:VARIABLE)"
factory,BigFactorySample2,"$.properties.globalParameters.'Env-Code'.value","PROD"

Column VALUE

You can define 3 types of values in column Value: number, string, (nested) JSON object.
If you need to use comma (,) in Value column - remember to enclose entire value within double-quotes ("), like in this example below:

pipeline,PL_Wait_Dynamic,parameters.WaitInSec,"{'type': 'int32','defaultValue': 22}"

Using Tokens as dynamic values

You can use token syntax to define expression which should be replaced by value after reading CSV config file process. Currently PowerShell expression for environment is supported, which is: $Env:VARIABLE or $($Env:VARIABLE).
Assuming you have an Environment Variable name USERDOMAIN with value CONTOSO, this line from config file:

linkedService,AKV,typeProperties.baseUrl,"https://$Env:USERDOMAIN.vault.azure.net/"

will become that one after reading from disk:

linkedService,AKV,typeProperties.baseUrl,"https://CONTOSO.vault.azure.net/"

Having that in mind, you can leverage variables defined in Azure DevOps pipeline to replace tokens without extra task. This is possible because all pipeline's variables are available as environment variables within the agent.

Stage parameter

This parameter is optional. When defined, the 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 .\deployment\config-UAT.csv

Use the optional [-Stage] parameter when executing Publish-AdfV2FromJson module to replace values for/with properties specified in config file(s).

There are 2 ways to provide value for Stage parameter:

Stage value as environment code/name

You can provide short environment code, e.g. UAT, PROD for Stage parameter.
In that case, planning deployment into UAT and PROD environments you need to create these files (subfolder deployment in relation to main ADF location):

SQLPlayerDemo  
    dataflow  
    dataset
    deployment               (new folder)  
        config-uat.csv       (file for UAT environment)
        config-prod.csv      (file for PROD environment)
    factory
    integrationRuntime  
    linkedService  
    pipeline  
    trigger  

File name must follow the pattern: config-{stage}.csv and be located in folder named: deployment.

Stage value as full path to CSV config file

The second way is to provide full path to configuration file.
For example, if you provide c:\MyCode\adf\uat-parameters.csv, an exact file will be use to read configuration as the value ends with ".csv". Although, in that case, the file may be located anywhere, it's recommended to keep them along with other ADF files.

JSON format of Config file

If you prefer using JSON rather than CSV for setting up configuration - JSON files are also supported now. In that case, Stage parameter must be set with full path to configuration file. Take a look at the following example:

{
  "LS_AzureDatabricks": [
    {
      "name": "$.properties.typeProperties.existingClusterId",
      "value": "$($Env:DatabricksClusterId)",
      "action": "add"
    },
    {
      "name": "$.properties.typeProperties.encryptedCredential",
      "value": "",
      "action": "remove"
    }
  ],
  "LS_AzureKeyVault": [
    {
      "name": "$.properties.typeProperties.baseUrl",
      "value": "https://kv-$($Env:Environment).vault.azure.net/",
      "action": "update"
    }
  ]
}

Step: Stoping triggers

This block stops all triggers which must be stopped due to deployment.

Operation might be skipped when StopStartTriggers = false in Publish Options

Step: Deployment of ADF objects

This step is actually responsible for doing all the stuff. The mechanism is smart enough to publish all objects in the right order, thence a developer doesn't need to care of object names due to deployment failure any longer.

Find out Publish Option capabilities in terms of filtering objects intended to be deployed.

Step: Deleting objects not in source

This process removes all objects from ADF service whom couldn't be found in the source (ADF code).
The mechanism is smart enough to dropping the objects in right order.

Operation might be skipped when DeleteNotInSource = false in Publish Options

Step: Restarting all triggers

Restarting all triggers that should be enabled.

Operation might be skipped when StopStartTriggers = false in Publish Options

Publish from Azure DevOps

There are two ways you can deploy Azure Data Factory with this approach (directly from code) within Azure DevOps Pipeline using:

• Publish Azure Data factory task (recommended)
• Azure PowerShell task

Using Publish Azure Data factory (task)

Custom Build/Release Task for Azure DevOps has been prepared as a very convenient way of configuring deployment task in Release Pipeline (Azure DevOps). Although it's only UI put on top of azure.datafactory.tools PS module, it gives users great experience if they don't have PowerShell skills or perhaps prefer using a clear and simple fields configuration approach.
The "Publish Azure Data factory" task is available for free and open-source. You can install it from Microsoft MarketPlace onto your organisation.
More information: Marketplace | Source code and documentation

Using Azure PowerShell (task)

Having this as a PowerShell module, it is very easy to configure a Release Pipeline in Azure DevOps to publish ADF code as if it was running from a local machine. All the steps you must create are:

• Download & install Az.DataFactory and azure.datafactory.tools PowerShell modules
• Execute Publish-AdfV2FromJson method with parameters

Both steps you can be found here:

# Step 1
Install-Module Az.DataFactory -MinimumVersion "1.10.0" -Force
Install-Module -Name "azure.datafactory.tools" -Force
Import-Module -Name "azure.datafactory.tools" -Force

# Step 2
Publish-AdfV2FromJson -RootFolder "$(System.DefaultWorkingDirectory)/_ArtifactName/" -ResourceGroupName "$(ResourceGroupName)" -DataFactoryName "$(DataFactoryName)" -Location "$(Location)" -Stage "$(Release.EnvironmentName)"

YAML:

variables:
  ResourceGroupName: 'rg-devops-factory'
  DataFactoryName: 'SQLPlayerDemo'
steps:
- powershell: |
   Install-Module Az.DataFactory -MinimumVersion "1.10.0" -Force
   Install-Module -Name "azure.datafactory.tools" -Force
   Import-Module -Name "azure.datafactory.tools" -Force
  displayName: 'PowerShell Script'
steps:
- task: AzurePowerShell@4
  displayName: 'Azure PowerShell script: InlineScript'
  inputs:
    azureSubscription: 'Subscription'
    ScriptType: InlineScript
    Inline: |
     Publish-AdfV2FromJson -RootFolder "$(System.DefaultWorkingDirectory)/_ArtifactName_/" -ResourceGroupName "$(ResourceGroupName)" -DataFactoryName "$(DataFactoryName)" -Location "$(Location)" -Stage "$(Release.EnvironmentName)"
     
    FailOnStandardError: true
    azurePowerShellVersion: LatestVersion```
