Using Azure Key Vault Secrets in GitLab CI Jobs: A Step-by-Step Guide

In this article, we will discuss how to use Azure Key Vault secrets in GitLab CI jobs. This guide will provide a detailed context of the topic, covering key concepts and subtitles. We will also include code blocks, properly formatted according to the programming language, and ensure that the content inside the code block has the necessary indentation and tabulation needed.

Introduction

Azure Key Vault is a cloud-based service that provides secure storage of keys, secrets, and certificates. It enables you to centrally manage and control access to sensitive information, such as API keys, passwords, and tokens. GitLab CI/CD is a continuous integration and delivery tool that automates the software development process. By integrating Azure Key Vault with GitLab CI/CD, you can securely store and access sensitive information in your CI/CD pipelines.

Prerequisites

To follow this guide, you need to have the following:

• An Azure account with an active subscription
• An Azure Key Vault instance
• A GitLab account with a repository containing a .gitlab-ci.yml file
• Access to Azure Key Vault and GitLab CI/CD

Step 1: Configure OpenID Connect for Azure

To authenticate to Azure Key Vault from GitLab CI/CD, you need to configure OpenID Connect for Azure. This will enable you to retrieve temporary credentials to access Azure Key Vault secrets.

To configure OpenID Connect for Azure, follow the guide Configure OpenID Connect for Azure.

Step 2: Set up a Federated Identity Provider in GitLab

Once you have configured OpenID Connect for Azure, you need to set up a Federated Identity Provider in GitLab. This will enable GitLab to authenticate to Azure Key Vault using the temporary credentials.

To set up a Federated Identity Provider in GitLab, follow the guide Set up a Federated Identity Provider in GitLab.

Step 3: Create a GitLab CI/CD Variable for Azure Key Vault

Next, you need to create a GitLab CI/CD variable for Azure Key Vault. This variable will contain the URL of the Azure Key Vault instance and the name of the secret you want to access.

To create a GitLab CI/CD variable for Azure Key Vault, follow the guide Creating and Managing CI/CD Variables for Projects.

Step 4: Access Azure Key Vault Secrets in GitLab CI/CD Jobs

Finally, you can access Azure Key Vault secrets in GitLab CI/CD jobs. To do this, you need to use the Azure CLI or PowerShell scripts in your GitLab CI/CD jobs.

Here is an example of how to access an Azure Key Vault secret in a GitLab CI/CD job using the Azure CLI:
