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.
Use Azure Cloud Shell
Azure hosts Azure Cloud Shell, an interactive shell environment that you can use through your browser. Cloud Shell lets you use either
PowerShell to work with Azure services. You can use the Cloud Shell pre-installed commands to run the code in this article without having to install anything on your local environment.
To launch Azure Cloud Shell:
|Select Try It in the upper-right corner of a code block. Selecting Try It doesn't automatically copy the code to Cloud Shell.|
|Go to https://shell.azure.com or select the Launch Cloud Shell button to open Cloud Shell in your browser.|
|Select the Cloud Shell button on the top-right menu bar in the Azure portal.|
To run the code in this article in Azure Cloud Shell:
- Launch Cloud Shell.
- Select the Copy button on a code block to copy the code.
- Paste the code into the Cloud Shell session with Ctrl+Shift+V on Windows and Linux, or Cmd+Shift+V on macOS.
- Press Enter to run the code.
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.

Clean up deployment
After the sample script has been run, the following command can be used to remove the resource group and all resources associated with it.
az group delete --name myResourceGroup
This script uses the following commands to create a resource group, App Service app, Cosmos DB, and all related resources. Each command in the table links to command specific documentation.
||Creates a resource group in which all resources are stored.|
||Creates an App Service plan.|
||Creates an App Service app.|
||Creates a Cosmos DB account.|
||Lists connection strings for the specified Cosmos DB account.|
||Creates or updates an app setting for an App Service app. App settings are exposed as environment variables for your app.|
