 You will need a service principal to deploy an app to an Azure resource from Azure Pipelines. Since we are going to retrieve secrets in a pipeline, we will need to grant permission to the service when we create the Azure Key vault. 
 
-A service principal is automatically created by Azure Pipeline when you connect to an Azure subscription from inside a pipeline definition or when you create a new service connection from the project settings page. You can also manually create the service principal from the portal or using Azure CLI and re-use it across projects. It is recommended that you use an existing service principal when you want to have a pre-bdefined set of permissions.
