使用 CLI 将应用服务应用连接到 Cosmos DBConnect an App Service app to Cosmos DB using CLI

此示例脚本使用 Azure Cosmos DB 的用于 MongoDB 的 API 和应用服务应用来创建一个 Azure Cosmos DB 帐户。This sample script creates an Azure Cosmos DB account using the Azure Cosmos DB's API for MongoDB and an App Service app. 然后,它将使用应用设置将 MongoDB 连接字符串链接到 Web 应用。It then links a MongoDB connection string to the web app using app settings.

如果没有 Azure 订阅,可在开始前创建一个试用帐户If you don't have an Azure subscription, create a trial account before you begin.

如果选择在本地安装并使用 CLI,则需使用 Azure CLI 2.0 或更高版本。If you choose to install and use the CLI locally, you need Azure CLI version 2.0 or later. 若要查找版本,请运行 az --versionTo find the version, run az --version. 如果需要进行安装或升级,请参阅安装 Azure CLIIf you need to install or upgrade, see Install Azure CLI.

示例脚本Sample script

#/bin/bash

# Variables
appName="webappwithcosmosdb$RANDOM"
location="ChinaNorth"

# Create a Resource Group 
az group create --name myResourceGroup --location $location

# Create an App Service Plan
az appservice plan create --name myAppServicePlan --resource-group myResourceGroup --location $location
# Create a Web App
az webapp create --name $appName --plan myAppServicePlan --resource-group myResourceGroup 

# Create a Cosmos DB with MongoDB API
az cosmosdb create --name $appName --resource-group myResourceGroup --kind MongoDB

# Get the MongoDB URL
connectionString=$(az cosmosdb list-connection-strings --name $appName --resource-group myResourceGroup \
--query connectionStrings[0].connectionString --output tsv)

# Assign the connection string to an App Setting in the Web App
az webapp config appsettings set --name $appName --resource-group myResourceGroup \
--settings "MONGODB_URL=$connectionString" 

清理部署Clean up deployment

运行示例脚本后,可以使用以下命令删除资源组以及与其关联的所有资源。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
