# Azure Identity SDK for Rust Authentication library for Azure SDK clients using Microsoft Entra ID (formerly Azure AD). ## Installation ```sh cargo add azure_identity ``` ## Environment Variables ```bash # Service Principal (for production/CI) AZURE_TENANT_ID=<your-tenant-id> AZURE_CLIENT_ID=<your-client-id> AZURE_CLIENT_SECRET=<your-client-secret> # User-assigned Managed Identity (optional) AZURE_CLIENT_ID=<managed-identity-client-id> ``` ## DeveloperToolsCredential The recommended credential for local development. Tries developer tools in order (Azure CLI, Azure Developer CLI): ```rust use azure_identity::DeveloperToolsCredential; use azure_security_keyvault_secrets::SecretClient; let credential = DeveloperToolsCredential::new(None)?; let client = SecretClient::new( "https://my-vault.vault.azure.net/", credential.clone(), None, )?; ``` ### Credential Chain Order | Order | Credential | Environment | |-------|-----------|-------------| | 1 | AzureCliCredential | `az login` | | 2 | AzureDeveloperCliCredential | `azd auth login` | ## Credential Types | Credential | Usage | |------------|-------| | `DeveloperToolsCredential` | Local development - tries CLI tools | | `ManagedIdentityCredential` | Azure VMs, App Service, Functions, AKS | | `WorkloadIdentityCredential` | Kubernetes workload identity | | `ClientSecretCredential` | Service principal with secret | | `ClientCertificateCredential` | Service principal with certificate | | `AzureCliCredential` | Direct Azure CLI auth | | `AzureDeveloperCliCredential` | Direct azd CLI auth | | `AzurePipelinesCredential` | Azure Pipelines service connection | | `ClientAssertionCredential` | Custom assertions (federated identity) | ## ManagedIdentityCredential For Azure-hosted resources: ```rust use azure_identity::ManagedIdentityCredential; // System-assigned managed identity let credential = ManagedIdentityCredential::new(None)?; // User-assigned managed identity let options = ManagedIdentityCredentialOptions { client_id: Some("<user-assigned-mi-client-id>".into()), ..Default::default() }; let credential = ManagedIdentityCredential::new(Some(options))?; ``` ## ClientSecretCredential For service principal with secret: ```rust use azure_identity::ClientSecretCredential; let credential = ClientSecretCredential::new( "<tenant-id>".into(), "<client-id>".into(), "<client-secret>".into(), None, )?; ``` ## Best Practices 1. **Use `DeveloperToolsCredential` for local dev** — automatically picks up Azure CLI 2. **Use `ManagedIdentityCredential` in production** — no secrets to manage 3. **Clone credentials** — credentials are `Arc`-wrapped and cheap to clone 4. **Reuse credential instances** — same credential can be used with multiple clients 5. **Use `tokio` feature** — `cargo add azure_identity --features tokio` ## Reference Links | Resource | Link | |----------|------| | API Reference | https://docs.rs/azure_identity | | Source Code | https://github.com/Azure/azure-sdk-for-rust/tree/main/sdk/identity/azure_identity | | crates.io | https://crates.io/crates/azure_identity | ## When to Use This skill is applicable to execute the workflow or actions described in the overview. ## Diff History - **v00.33.0**: Ingested from antigravity-awesome-skills community repo --- ## Why This Skill Exists Implement — Azure Identity SDK for Rust authentication.
