Security Considerations
-
Environment Variable Security: These variables contain sensitive credentials and should be:
- Never committed to version control
- Stored securely in production environments
- Rotated regularly
-
Access Control: Ensure that only authorized services and users have access to these environment variables.
-
Default Credentials: These are intended for development and testing. In production, consider using more secure credential management systems.
Usage Examples
Development Environment
# .env.local
AAI_DEFAULT_OPENAI_API_KEY=sk-your-openai-key
AAI_DEFAULT_ANTHROPHIC=sk-ant-your-anthropic-key
AAI_DEFAULT_AWS_BEDROCK_ACCESS_KEY=AKIA...
AAI_DEFAULT_AWS_BEDROCK_SECRET_KEY=your-secret-key
Docker Environment
# docker-compose.yml
environment:
- AAI_DEFAULT_OPENAI_API_KEY=${OPENAI_API_KEY}
- AAI_DEFAULT_ANTHROPHIC=${ANTHROPHIC_API_KEY}
- AAI_DEFAULT_AWS_BEDROCK_ACCESS_KEY=${AWS_ACCESS_KEY}
- AAI_DEFAULT_AWS_BEDROCK_SECRET_KEY=${AWS_SECRET_KEY}
Troubleshooting
Common Issues
-
Missing Variables: If a required variable is not set, the corresponding AAI node will throw an error with a descriptive message.
-
Invalid Credentials: Ensure that the API keys and credentials are valid and have the necessary permissions.
-
Network Issues: Some services may require specific network configurations or firewall rules.
