Integrate the Azure Cosmos DB for NoSQL with Service Connector

1. Install dependencies.

   dotnet add package Microsoft.Azure.Cosmos
   dotnet add package Azure.Identity
   

2. Authenticate using Azure.Identity NuGet package and get the endpoint URL from the environment variable added by Service Connector. When using the code below, uncomment the part of the code snippet for the authentication type you want to use.

   using Microsoft.Azure.Cosmos;
   using Azure.Core;
   using Azure.Identity;
   using System; 
   
   // Uncomment the following lines corresponding to the authentication type you want to use.
   // For system-assigned identity.
   // TokenCredential credential = new DefaultAzureCredential();
   
   // For user-assigned identity.
   // TokenCredential credential = new DefaultAzureCredential(
   //     new DefaultAzureCredentialOptions
   //     {
   //         ManagedIdentityClientId = Environment.GetEnvironmentVariable("AZURE_COSMOS_CLIENTID");
   //     }
   // );
   
   // For service principal.
   // TokenCredential credential = new ClientSecretCredential(
   //     tenantId: Environment.GetEnvironmentVariable("AZURE_COSMOS_TENANTID")!,
   //     clientId: Environment.GetEnvironmentVariable("AZURE_COSMOS_CLIENTID")!,
   //     clientSecret: Environment.GetEnvironmentVariable("AZURE_COSMOS_CLIENTSECRET")!,
   //     options: new TokenCredentialOptions()
   // );
   
   // Create a new instance of CosmosClient using the credential above
   using CosmosClient client = new(
       accountEndpoint: Environment.GetEnvironmentVariable("AZURE_COSMOS_RESOURCEENDPOINT")!,
       tokenCredential: credential
   );

2. Authenticate using @azure/identity npm package and get the endpoint URL from the environment variable added by Service Connector. When using the code below, uncomment the part of the code snippet for the authentication type you want to use.

   import { CosmosClient } from "@azure/cosmos";
   const { DefaultAzureCredential } = require("@azure/identity");
   
   // Uncomment the following lines corresponding to the authentication type you want to use.
   // For system-assigned managed identity.
   // const credential = new DefaultAzureCredential();
   
   // For user-assigned managed identity.
   // const credential = new DefaultAzureCredential({
   //     managedIdentityClientId: process.env.AZURE_COSMOS_CLIENTID
   // });
   
   // For service principal.
   // const credential = new ClientSecretCredential(
   //     tenantId: process.env.AZURE_COSMOS_TENANTID,
   //     clientId: process.env.AZURE_COSMOS_CLIENTID,
   //     clientSecret: process.env.AZURE_COSMOS_CLIENTSECRET
   // );
   
   // Create a new instance of CosmosClient using the credential above
   const cosmosClient = new CosmosClient({ 
       process.env.AZURE_COSMOS_RESOURCEENDPOINT, 
       aadCredentials: credential
   });
   

For other languages, you can use the endpoint URL and other properties that Service Connector sets to the environment variables to connect to Azure Cosmos DB for NoSQL. For environment variable details, see Integrate Azure Cosmos DB for NoSQL with Service Connector.
