Azure Key Vault is a powerful service provided by Microsoft Azure that allows you to securely store and manage sensitive information such as API keys, passwords, and connection strings. Azure Pipelines, on the other hand, is a versatile CD platform offered by Azure. By integrating Azure Key Vault secrets into Azure Release Pipelines, you can enhance the security of your CD processes and ensure that sensitive information is protected.
In this blog post, we will guide you through the process of leveraging Azure Key Vault secrets in Azure Release Pipelines, enabling you to securely retrieve and use them in your CD workflows.
