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.
