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. You can use either Bash or PowerShell with Cloud Shell to work with Azure services. You can use the Cloud Shell preinstalled commands to run the code in this article without having to install anything on your local environment.
To start 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:
Start Cloud Shell.
Select the Copy button on a code block to copy the code.
Paste the code into the Cloud Shell session by selecting Ctrl+Shift+V on Windows and Linux or by selecting Cmd+Shift+V on macOS.
Select 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
