In modern application development, managing secrets and sensitive configuration data is crucial. Azure Key Vault provides a secure and efficient way to store these sensitive values. In this article, we’ll explore how to integrate Azure DevOps pipelines with Azure Key Vault using templates and variable groups.
Before we begin, ensure you have the following:
- An Azure DevOps project set up with appropriate permissions.
- An Azure Key Vault with secrets you want to access in your pipelines.
- Basic knowledge of YAML and Azure DevOps pipelines.
Using Variable Groups with Azure Key Vault
Variable groups in Azure DevOps allow you to define a set of variables that can be reused across multiple pipelines. When combined with Azure Key Vault, you can securely store and reference sensitive information.
Creating a Variable Group
- Navigate to your Azure DevOps project.
- Go to
- Click on
+ Variable groupto create a new group.
- Add variables and their values, leaving the sensitive ones empty.
Linking Variable Groups to Key Vault
To access secrets from Azure Key Vault in your pipelines, you’ll need to link your variable groups:
- In the Azure DevOps project, go to
- Select the variable group you created earlier.
- Click on
Link secrets from an Azure key vault as variables.
- Choose your Azure subscription and Key Vault.
Now, your variable group is linked to the Key Vault, allowing you to reference secrets in your pipeline.
For more detailed information, refer to the official documentation on Variable Groups.
Integrating Azure Key Vault with Pipelines
Azure Key Vault integration with Azure DevOps pipelines allows you to securely store and use sensitive information in your CI/CD process. To learn more about this integration, refer to the official documentation on Azure Key Vault integration in Release pipelines.
Using Templates for Code Reusability
Azure DevOps templates provide a way to define reusable, parameterized pipeline configurations. When combined with variable groups and Key Vault, you can streamline your CI/CD process.
Creating a Template
Create a new YAML file in your repository (e.g.,
azure-pipeline-template.yml). This template will define the structure of your pipeline and accept parameters for customization.
parameters: - name: environment displayName: 'Environment' type: string default: 'dev' - name: buildConfiguration displayName: 'Build Configuration' type: string default: 'Release' jobs: - job: BuildAndDeploy displayName: 'Build and Deploy Job' pool: vmImage: 'windows-latest' steps: - script: | echo "Building for $ environment with configuration: $" # Add your build and deployment steps here
In this template, we define two parameters:
buildConfiguration. These parameters allow for customization when the template is used in a pipeline. Note how we reference the parameters using
Using the Template in a Pipeline
In your pipeline YAML file (e.g.,
main-pipeline.yml), reference the template and pass the desired values for the parameters. Additionally, declare your regular variables using name/value pairs.
variables: - name: regularVariable value: 'This is a regular variable' - name: MyRegularVariable value: 'This is another regular variable' - group: 'MyVariableGroup' # Reference to your variable group trigger: branches: exclude: - '*' pr: branches: include: - '*' jobs: - template: azure-pipeline-template.yml parameters: environment: ' prod' buildConfiguration: 'Debug'
In the above example, the template is referenced, and the
environment parameter is set to
buildConfiguration is set to
'Debug'. Note how we have defined our Variables and Variable Group references, when including both in your Variable block you must reference un-grouped variables using name/value syntax, as defined in the documentation.
