To connect on-premises #Terraform with #Azure #DevOps

To connect on-premises Terraform with Azure DevOps, you can follow these general steps:

1. Install Terraform: Ensure that you have Terraform installed on your on-premises machine. You can download the Terraform binary from the official website (https://www.terraform.io/downloads.html) and follow the installation instructions.
2. Create a Terraform Configuration: Set up your Terraform configuration files to define the infrastructure you want to manage. These files typically have a .tf extension and describe the resources, providers, variables, and backend configurations.
3. Initialize Backend: Choose a backend for storing Terraform state. Azure Storage Account is a common choice for Azure DevOps. Configure the backend block in your Terraform configuration files to store the state in Azure Storage.

Example backend configuration for Azure Storage:

terraform { backend "azurerm" { storage_account_name = "your_storage_account_name" container_name = "your_container_name" key = "your_state_file.tfstate" access_key = "your_storage_account_access_key" sas_token = "optional_sas_token" } }

4. Set up Azure DevOps: In your Azure DevOps organization, create a new project or use an existing one. Ensure that you have the necessary permissions to manage pipelines and configure service connections.

5 . Create an Azure DevOps Pipeline: Set up a pipeline in Azure DevOps to automate the execution of Terraform commands. Define the pipeline using YAML or classic UI-based editor. You'll need to specify the steps, agent pool, and resources required for running Terraform.

6. Configure Azure DevOps Service Connection: To connect to your on-premises environment, create a service connection in Azure DevOps. This connection will enable communication between Azure DevOps and your on-premises machine.

• In Azure DevOps, go to your project and navigate to "Project Settings."
• Under "Pipelines," select "Service Connections."
• Click on "New Service Connection" and choose "Azure Resource Manager."
• Follow the prompts to provide the required information, such as the subscription, authentication method, and other details.

7. Update Azure DevOps Pipeline: Modify your Azure DevOps pipeline configuration to include the Terraform tasks and reference the service connection created in the previous step.

Example Terraform pipeline steps in Azure DevOps YAML:

steps: - task: UseTerraform@0 inputs: provider: 'azurerm' command: 'init' backendServiceArm: 'your_service_connection_name' backendAzureRmResourceGroupName: 'your_resource_group_name' backendAzureRmStorageAccountName: 'your_storage_account_name' backendAzureRmContainerName: 'your_container_name' backendAzureRmKey: 'your_state_file.tfstate' - task: UseTerraform@0 inputs: provider: 'azurerm' command: 'apply'

8. Commit and Trigger Pipeline: Commit your Terraform configuration files and the Azure DevOps pipeline configuration to your repository. Trigger the pipeline to start the execution of Terraform commands against your on-premises environment.

Once your pipeline runs, it will connect to your on-premises machine and execute the Terraform commands defined in your pipeline configuration, enabling you to manage your infrastructure using Terraform with Azure DevOps.
