Connect an App Service app to Cosmos DB using CLI
This sample script creates an Azure Cosmos DB account using the Azure Cosmos DB's API for MongoDB and an App Service app. It then links a MongoDB connection string to the web app using app settings.
Open Azure Cloud Shell
Azure Cloud Shell is a free, interactive shell that you can use to run the steps in this article. Common Azure tools are preinstalled and configured in Cloud Shell for you to use with your account. Select Copy to copy the code, paste it in Cloud Shell, and then press Enter to run it. There are a few ways to open Cloud Shell:
|Select Try It in the upper-right corner of a code block.|
|Open Cloud Shell in your browser.|
|Select the Cloud Shell button on the menu in the upper-right corner of the Azure portal.|
If you choose to install and use the CLI locally, you need Azure CLI version 2.0 or later. To find the version, run
az --version. If you need to install or upgrade, see Install Azure CLI.
