CI/CD Azure Synapse Workspace with Azure Devops

Question

Dear all, 

I am working on CI/CD between Azure Synapse Workspace with Azure Devops. 

I have source code from someone else who work on this project before and it works well and I try to understand it and create my own project on it. right now, I have issues of the deplolyment stage: 

1.  under release, people usually add Git Repos in Artifacts, but in my case, I have a build synapse workspace before add Git Repos. 

So my question: why do we need to Build synapse workspace before add Git Repos?  

below is the source code for Build synapse workspace:

Could you tell me why do we need this?

2. in my Repos, we have develop branch (for CI) and prod branch (for CD). Under my Repos in develop branch, I have two yaml files which relates with pipeline in Pipelines. I have no idea how does it generate. Will these two yaml files will generate automatically when I create pi 

Many thanks, 

Joan

Why Build Synapse Workspace Before Adding Git Repos?

Building the Synapse workspace before adding Git repositories is a step that ensures the Synapse environment is correctly set up and all necessary configurations and dependencies are in place. This process typically includes:

1. Creating and configuring the Synapse workspace, including linked services, datasets, and other necessary resources.
2. Ensuring the workspace is deployed with a consistent initial state that can then be versioned and managed through Git repositories.
3. Ensuring that the environment is correctly configured and operational before integrating with version control, which helps to avoid issues later in the deployment pipeline.

YAML Files in the Repository

The YAML files you mentioned are used for defining CI/CD pipelines in Azure DevOps. These pipelines automate the build, test, and deployment processes.

1. Develop Branch (CI): The YAML file in this branch is responsible for Continuous Integration (CI). It usually contains steps for:
   • Building and validating code.
   • Running unit tests.
   • Preparing artifacts for deployment.
2. Prod Branch (CD): The YAML file in this branch is responsible for Continuous Deployment (CD). It typically includes steps for:
   • Deploying the validated code to the production environment.
   • Running integration and end-to-end tests.
   • Finalizing the deployment process.

Automatic Generation of YAML Files

YAML files are not automatically generated when you create a pipeline in Azure DevOps. Instead, these files need to be manually created and defined based on your specific CI/CD requirements. Here is an example :

trigger:

- develop

pool:

  vmImage: 'ubuntu-latest'

steps:

- task: UsePythonVersion@0

  inputs:

    versionSpec: '3.x'

    addToPath: true

- script: |

    python -m pip install --upgrade pip

    pip install -r requirements.txt

  displayName: 'Install dependencies'

- task: AzureCLI@2

  inputs:

    azureSubscription: 'your-azure-subscription'

    scriptType: 'bash'

    scriptLocation: 'inlineScript'

    inlineScript: |

      az synapse workspace create --name your-workspace --resource-group your-resource-group --location your-location

  displayName: 'Deploy Synapse Workspace'
