Use Azure Key Vault secrets in GitLab CI/CD

You can use secrets stored in the Azure Key Vault in your GitLab CI/CD pipelines.

Prerequisites:

• Have a key vault on Azure.
• Have an application with key vault permissions.
• Configure OpenID Connect in Azure to retrieve temporary credentials.
• Add CI/CD variables to your project to provide details about your Vault server:
  • AZURE_KEY_VAULT_SERVER_URL: The URL of your Azure Key Vault server, such as https://vault.example.com.
  • AZURE_CLIENT_ID: The client ID of the Azure application.
  • AZURE_TENANT_ID: The tenant ID of the Azure application.

Use Azure Key Vault secrets in a CI/CD job

You can use a secret stored in your Azure Key Vault in a job by defining it with the azure_key_vault keyword:

job:
  id_tokens:
    AZURE_JWT:
      aud: 'azure'
  secrets:
    DATABASE_PASSWORD:
      token: AZURE_JWT
      azure_key_vault:
        name: 'test'
        version: 'test'

In this example:

• name is the name of the secret.
• version is the version of the secret.
• GitLab fetches the secret from Azure Key Vault and stores the value in a temporary file. The path to this file is stored in a DATABASE_PASSWORD CI/CD variable, similar to file type CI/CD variables.
