AWS Credentials

Dynantic uses boto3 under the hood, so it follows the standard AWS credential resolution order:

  1. Environment variables (AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY)
  2. Shared credentials file (~/.aws/credentials)
  3. AWS config file (~/.aws/config)
  4. IAM role (on EC2, Lambda, ECS, etc.)

Lambda / ECS

On AWS Lambda or ECS, credentials are provided automatically via the execution role. No configuration needed.

For local development with LocalStack, see the integration guide.
