fix(02-use-cases): Add multi-region support for SRE-Agent (#246) * Add multi-region support for SRE-Agent - Add AWS region configuration parameter to agent_config.yaml - Update gateway main.py to validate region matches endpoint URL - Modify SRE agent to read region from config and pass through function chain - Update memory client and LLM creation to use configurable region - Fixes hardcoded us-east-1 region dependencies Closes #245 * Move architecture file to docs/ and improve setup instructions - Move sre_agent_architecture.md to docs/ folder for better organization - Update graph export code to generate architecture file in docs/ folder - Add automatic docs directory creation if it doesn't exist - Improve README setup instructions: - Fix .env.example copy path to use sre_agent folder - Add note that Amazon Bedrock users don't need to modify .env - Add START_API_BACKEND variable to conditionally start backend servers - Useful for workshop environments where backends are already running * Improve gateway configuration documentation and setup instructions - Update config.yaml.example to use REGION placeholder instead of hardcoded us-east-1 - Add gateway configuration step to README setup instructions - Document .cognito_config file in auth.md automated setup section - Remove duplicate credential_provider_name from config.yaml.example - Update configuration.md to include .cognito_config in files overview - Add clear instructions to copy and edit gateway/config.yaml before creating gateway * Improve IAM role guidance and region handling - Add clear guidance about IAM role options in gateway/config.yaml.example - Explain that testing can use current EC2/notebook role - Recommend dedicated role for production deployments - Add aws sts get-caller-identity command to help users find their role - Update deployment scripts to use AWS_REGION env var as fallback - Scripts now follow: CLI arg -> AWS_REGION env var -> us-east-1 default * Remove unnecessary individual Cognito ID files - Remove creation of .cognito_user_pool_id file - Remove creation of .cognito_client_id file - Keep only .cognito_config as the single source of truth - Simplifies configuration management * Implement region fallback logic for SRE Agent - Added region fallback chain: agent_config.yaml -> AWS_REGION env -> us-east-1 - Modified agent_config.yaml to comment out region parameter to enable fallback - Updated multi_agent_langgraph.py with comprehensive fallback implementation - Added logging to show which region source is being used - Ensures flexible region configuration without breaking existing deployments - Maintains backward compatibility while adding multi-region support 2025-08-13 08:32:37 -04:00			`# SRE Agent Architecture`
