Introduction

In this repository you will find a way to setup your build and release pipeline in Azure DevOps (Azure Pipelines) to use source control for your Azure Data Explorer functions. Any commands for your Azure Data Explorer database within CSL files can be used, although this reference is tested for functions.

This reference uses the Azure Data Explorer Commands utility task for Azure Pipelines. This must be enabled in your tenant, and can be acquired from the Visual Studio Marketplace: https://marketplace.visualstudio.com/items?itemName=Azure-Kusto.PublishToADX.

Build

As part of your build pipeline, the script file pre-deploy.sh will run to process the CSL files (located in /src) with your Azure Data Explorer commands. The script will capture environment variables from Azure DevOps and create a record of the ingestion in your database.

The build pipeline can be defined as shown below (see azure-pipelines.yml). Adjust according to your solution.

Release

In your release pipeline, a few Azure Data Explorer commands can be included. One is needed to ensure that the table is available in Azure Data Explorer, and one to ingest the CSL files to deploy the functions.

For the table creation, see Init.csl for a reference as to how this can be done.

The release pipeline can be defined as shown below. Adjust according to your solution.

  AadClientId: '...'
  AadClientSecret: '...'
  AdxClusterName: '...'
  AdxClusterRegion: '...'
  AdxDatabaseName: '...'

Modify and test

The script file pre-deploy.sh uses environment variables available during the build in Azure Pipelines. However, it can still be modified and executed with the sample folder /src in your own environment. It is built to run on Linux-based systems.

./pre-deploy.sh

After running the script, a new folder named publish will be created with the processed CSL files.

Usage

Once everything is assembled. Records of the ingestion can then be found in the Deployments table in Azure Data Explorer.
