Loading... Loading... Menu This document explains how the Serverless Framework manages AWS credentials to deploy and interact with AWS resources on your behalf. Proper credential management is critical for security and ensuring that the framework can create and manage cloud resources according to your permissions. The Serverless Framework needs secure access to your AWS account to deploy and manage resources. This page covers various methods for providing AWS credentials to the framework, from simple local development setups to advanced production configurations with multiple accounts and roles.

Sources: docs/providers/aws/guide/credentials.md24-27 The Serverless Framework provides multiple ways to connect to AWS, with varying levels of complexity and security. Choose the method that best fits your development workflow and security requirements. The simplest approach is to store AWS credentials locally on your machine. The Serverless Framework can walk you through this process.

Process: - Run the serverless command - Select "Save AWS Credentials in a Local Profile" - Create an IAM user with appropriate permissions - Enter the generated Access Key and Secret Access Key - Credentials are stored in ~/.aws/credentials Sources: docs/providers/aws/guide/credentials.md44-61 For teams or scenarios requiring more sophisticated credential management, the Serverless Framework supports the standard AWS credentials provider chain, which includes: - Environment Variables: Using AWS_ACCESS_KEY_ID ,AWS_SECRET_ACCESS_KEY , etc.

AWS SSO: Configured via the AWS CLI - Shared Credentials File: Credentials in ~/.aws/credentials - IAM Roles for EC2: When running on EC2 instances - AWS Profiles: Using the AWS_PROFILE environment variable To use these methods, select "Skip & Set Later (AWS SSO, ENV Vars)" during the onboarding process. Sources: docs/providers/aws/guide/credentials.md63-83 Resolvers provide a flexible way to specify AWS credentials directly in your Serverless configuration files. This approach allows you to manage different credentials for different environments or services.

You define resolvers in your serverless.yml file within the stages section: You can define multiple resolvers for different AWS accounts and select which one to use for deployment: In this example, project-specific-account is used for deployment credentials, while both resolvers can be used to reference variables. Sources: docs/providers/aws/guide/credentials.md85-156 The Serverless Dashboard provides a streamlined way to manage AWS credentials through IAM roles, eliminating the need to manage local AWS credentials.

Process: - Create a Serverless Framework account - Open the Dashboard and navigate to "Settings" > "Integrations" - Click "Add Integrations" and select "AWS Access Role" - Complete the CloudFormation stack creation in your AWS account - Deploy your service using the Dashboard Provider This method creates an IAM role in your AWS account that the Serverless Framework uses to deploy your services. Sources: docs/providers/aws/guide/credentials.md206-231 For production environments, a more sophisticated multi-account setup is recommended to properly separate environments and manage access control.

The recommended setup includes: - Management Account: Used only for account management, not for deployments - Set up AWS Organizations - Enable IAM Identity Center - Create user accounts for team members - Stage Accounts: Separate accounts for different environments - Development account for testing - Production account for live systems - Clear separation prevents development changes from affecting production - Developer Accounts: Individual AWS accounts for each developer - Provides isolation for testing - Prevents conflicts between developers - Simplifies onboarding and offboarding - Combine with Serverless Dashboard Providers: - Create providers for each account in Serverless Dashboard - Link providers to specific stages Sources: docs/providers/aws/guide/credentials.md234-287 When you run a Serverless Framework command that interacts with AWS, the framework follows a specific process to find and use credentials.

The credential resolution order is: - Explicitly defined resolver in provider.resolver - Explicitly defined profile in provider.profile - Single defined resolver (if only one exists) - Standard AWS credential provider chain Sources: docs/providers/aws/guide/credentials.md196-205 When managing AWS credentials, keep these security best practices in mind: - Least Privilege: Use IAM policies that grant only the permissions required - Avoid Hardcoding: Never commit credentials to version control - Rotate Keys: Regularly rotate access keys for IAM users - Use Roles: Prefer IAM roles over long-lived access keys when possible - Separate Environments: Use different AWS accounts for development and production Sources: docs/providers/aws/guide/credentials.md234-242 When using Serverless Compose to manage multiple services, credential management becomes even more important.

Compose allows you to: - Deploy multiple services in parallel - Share outputs between services - Deploy services with different credentials You can specify different AWS credentials for different services in your serverless-compose.yml file: Sources: docs/guides/compose.md22-31 Common credential-related issues and their solutions: Refresh this wiki - AWS Credentials Management - Overview - Credential Management Methods - 1.
