[License](#license) 23 | 24 | 25 | ## Overview 26 | In this project, we will set up an Amazon Bedrock agent with an action group that can translate natural language queries (NLQ) into SQL queries. The agent will query an Amazon Athena database, but the concept can be extended to most SQL databases. 27 | 28 | For those who prefer an Infrastructure-as-Code (IaC) solution, we provide an AWS CloudFormation template that will deploy all the necessary resources. If you would like to deploy via AWS CloudFormation, please refer to the guide in the section below. 29 | 30 | Alternatively, this README will walk you through the step-by-step process to set up the Amazon Bedrock agent manually using the AWS Console. 31 | 32 | ## Solution Overview 33 | This solution integrates Amazon Bedrock agents, AWS Lambda, Amazon Athena, and AWS Glue to process real-time user queries by translating natural language inputs into SQL queries to interact with data stored in Amazon S3. The Amazon Bedrock agent, acting as the central orchestrator, receives user inputs from an interface hosted on an EC2 instance. Using a chain-of-thought mechanism, it breaks down complex queries and delegates tasks to the appropriate AI models and services. The agent utilizes an action group, defined by OpenAPI schemas, to structure and execute multiple tasks. This action group interacts with a Lambda function, which processes SQL queries generated by the Bedrock agent and runs them through Amazon Athena for analysis. 34 | 35 | AWS Glue supports this process by reading unstructured data from Amazon S3, creating structured tables through its Data Catalog and crawlers, making it ready for Athena's queries. The results of these queries are stored back in Amazon S3 for easy access. The entire system is designed to be serverless, scalable, and secure, providing a flexible solution to handle diverse and complex queries with minimal infrastructure overhead. 36 | 37 | ## Prerequisites 38 | - An active AWS Account. 39 | - Familiarity with AWS services like Amazon Bedrock, Amazon S3, AWS Lambda, Amazon Athena, and Amazon EC2. 40 | - Access will need to be granted to the **Titan Embeddings G1 - Text** and **Anthropic: Claude 3 Haiku** model from the Amazon Bedrock console. 41 | 42 | 43 | ## Architecture Diagram 44 | 45 | ![Diagram](images/diagram.png) 46 | 47 | 1. Company data is loaded into Amazon S3, which serves as the data source for AWS Glue. 48 | 49 | 2. Amazon Athena is a serverless query service that analyzes S3 data using standard SQL, with AWS Glue managing the data catalog. AWS Glue reads unstructured data from S3, creates queryable tables for Athena, and stores query results back in S3. This integration, supported by crawlers and the Glue Data Catalog, streamlines data management and analysis. 50 | 51 | 3. The AWS Lambda function acts as the execution engine, processing the SQL query and interfacing with Amazon Athena. Proper configuration of resource policies and permissions is critical to ensure secure and efficient operations, maintaining the integrity of the serverless compute environment. 52 | 53 | 4. The main purpose of an action group in an Amazon Bedrock agent is to provide a structured way to perform multiple actions in response to a user's input or request. This allows the agent to take a series of coordinated steps to address the user's needs, rather than just performing a single action. This action group includes an OpenAPI schema which is needed so that the Amazon Bedrock agent knows the format structure and parameters needed for the action group to interact with the compute layer, in this case, a Lambda function. 54 | 55 | 5. An instruction prompt is provided to the Amazon Bedrock agent to help with orchestration. The Amazon Bedrock agent orchestrates the tasks by interpreting the input prompt and delegating specific actions to the LLM. 56 | 57 | 6. Collaboration with the task orchestrater in the previous step enables the LLM to process complex queries and generate outputs that align with the user's objectives. The chain of thought mechanism ensures that each step in the process is logically connected, leading to precise action execution. The model processes the user's natural language input, translating it into actionable SQL queries, which are then used to interact with data services. 58 | 59 | 7. The Amazon Bedrock agent endpoint serves as the bridge between the user's application that runs on an Amazon EC2 instance on AWS and the Amazon Bedrock agent, facilitating the transfer of input data in real-time. This setup is essential for capturing inputs that trigger the agent driven process. Natural language is used to query data, and return the response back to the user via the user interface. The results from the Athena query is returned to the user from the Lambda function through the Amazon Bedrock agent endpoint. 60 | 61 | 62 | ## Cost 63 | You are responsible for the cost of the AWS services used while running this Guidance. As of October 2024, the cost for running this Guidance with the default settings in the US West (Oregon) AWS Region is approximately $592.94 per month for processing 100,000 requests with an an input/output token count average of 700K. 64 | 65 | We recommend creating a [Budget](https://docs.aws.amazon.com/cost-management/latest/userguide/budgets-managing-costs.html) through [AWS Cost Explorer](https://aws.amazon.com/aws-cost-management/aws-cost-explorer/) to help manage costs. Prices are subject to change. For full details, refer to the pricing webpage for each AWS service used in this Guidance. 66 | 67 | | AWS Service | Dimensions | Cost [USD] | 68 | |---------------------------------------|-------------------------------------------|-------------| 69 | | EC2 Instance (t3.small) | Running an EC2 instance 24/7 per month | $17.74 | 70 | | AWS Lambda | 100k Invocations per month | ~$0.20 | 71 | | Amazon Bedrock Anthropic Claude 3 Haiku ***(Input)*** | 300K tokens per month (~200K words on average) | $75 | 72 | | Amazon Bedrock Anthropic Claude 3 Haiku ***(Output)*** | 400K tokens per month (~280K words on average) | $500 | 73 | | Amazon S3 (Simple Storage Service) | Total size of company reports is 1.1 KB | <$1 | 74 | | Amazon Athena | $5.00 per TB of data scanned | <$1 | 75 | 76 | ## Grant Model Access 77 | 78 | - We will need to grant access to the models that will be needed for the Amazon Bedrock agent. Navigate to the Amazon Bedrock console, then on the left of the screen, scroll down and select **Model access**.

After, save the changes. 138 | ![athena 2.5](images/athena2.5.png) 139 | 140 | ![athena 3](images/athena3.png) 141 | 142 | ## Testing the Bedrock Agent 143 | 144 | - Navigate to the Bedrock console. Go to the toggle on the left, and under **Builder tools** select ***Agents***, then the `athena-agent` that was created. 145 | 146 | ![navigate to agent](images/navigate_to_agent.png) 147 | 148 | 149 | - In the management console on the right, you have a test user interface. Enter prompts in the user interface to test your Bedrock agent. 150 | 151 | ![Agent test](images/agent_test.png) 152 | 153 | 154 | - Example prompts for Action Groups: 155 | 156 | 1. Show me all of the procedures in the imaging category that are insured. 157 | 158 | 2. Show me all of the customers that are vip, and have a balance over 200 dollars. 159 | 160 | 3. Return to me the number of procedures that are in the laboratory category. 161 | 162 | 4. Get me data of all procedures that were not insured, with customer names. 163 | 164 | 165 | - If you would like to launch the Streamlit app user interface, refer to **Step 7** below to configure the EC2 instance. 166 | 167 | 168 | 169 | ## Step-by-step Configuration and Setup 170 | 171 | ### Step 1: Creating S3 Buckets 172 | - Make sure that you are in the **us-west-2** region. If another region is required, you will need to update the region in the `invoke_agent.py` file on line 24 of the code. 173 | - **Domain Data Bucket**: Create an S3 bucket to store the domain data. For example, call the S3 bucket `athena-datasource-{alias}`. We will use the default settings. 174 | (Make sure to update **{alias}** with the appropriate value throughout the README instructions.) 175 | 176 | 177 | ![Bucket create 1](images/bucket_setup.gif) 178 | 179 | 180 | 181 | - Next, we will download .csv files that contain mock data for customers and procedures. Open up a terminal or command prompt, and run the following `curl` commands to download and save these files to the **Documents** folder: 182 | 183 | For **Mac** 184 | ```linux 185 | curl https://raw.githubusercontent.com/build-on-aws/bedrock-agent-txt2sql/main/S3data/mock-data-customers.csv --output ~/Documents/mock-data-customers.csv 186 | 187 | curl https://raw.githubusercontent.com/build-on-aws/bedrock-agent-txt2sql/main/S3data/mock-data-procedures.csv --output ~/Documents/mock-data-procedures.csv 188 | ``` 189 | 190 | For **Windows** 191 | 192 | ```windows 193 | curl https://raw.githubusercontent.com/build-on-aws/bedrock-agent-txt2sql/main/S3data/mock-data-customers.csv --output %USERPROFILE%\Documents\mock-data-customers.csv 194 | 195 | curl https://raw.githubusercontent.com/build-on-aws/bedrock-agent-txt2sql/main/S3data/mock-data-procedures.csv --output %USERPROFILE%\Documents\mock-data-procedures.csv 196 | ``` 197 | 198 | - These files are the datasource for Amazon Athena. Upload these files to S3 bucket `athena-datasource-{alias}`. Once the documents are uploaded, please review them. 199 | 200 | ![bucket domain data](images/bucket_domain_data.png) 201 | 202 | 203 | - **Amazon Athena Bucket**: Create another S3 bucket for the Athena service. Call it `athena-destination-store-{alias}`. You will need to use this S3 bucket when configuring Amazon Athena in the next step. 204 | 205 | 206 | ### Step 2: Setup Amazon Athena 207 | 208 | - Search for the Amazon Athena service, then navigate to the Athena management console. Validate that the **Query your data with Trino SQL** radio button is selected, then press **Launch query editor**. 209 | 210 | ![Athena query button](images/athena_query_edit_btn.png) 211 | 212 | - Before you run your first query in Athena, you need to set up a query result location with Amazon S3. Select the **Settings** tab, then the **Manage** button in the **Query result location and encryption** section. 213 | 214 | ![Athena manage button](images/athena_manage_btn.png) 215 | 216 | - Add the S3 prefix below for the query results location, then select the Save button: 217 | 218 | ```text 219 | s3://athena-destination-store-{alias} 220 | ``` 221 | 222 | ![choose athena bucket.png](images/choose_bucket.png) 223 | 224 | 225 | - Next, we will create an Athena database. Select the **Editor** tab, then copy/paste the following query in the empty query screen. After, select Run: 226 | 227 | ```sql 228 | CREATE DATABASE IF NOT EXISTS athena_db; 229 | ``` 230 | 231 | ![Create DB query](images/create_athena_db.png) 232 | 233 | 234 | - You should see query successful at the bottom. On the left side under **Database**, change the default database to `athena_db`, if not by default. 235 | 236 | - We'll need to create the `customers` table. Run the following query in Athena. `(Remember to update the {alias} field)`: 237 | 238 | ```sql 239 | CREATE EXTERNAL TABLE athena_db.customers ( 240 | `Cust_Id` integer, 241 | `Customer` string, 242 | `Balance` integer, 243 | `Past_Due` integer, 244 | `Vip` string 245 | ) 246 | ROW FORMAT DELIMITED 247 | FIELDS TERMINATED BY ',' 248 | LINES TERMINATED BY '\n' 249 | STORED AS TEXTFILE 250 | LOCATION 's3://athena-datasource-{alias}/'; 251 | ``` 252 | 253 | 254 | - Open another query tab and create the `procedures` table by running this query. `(Remember to update the {alias} field)`: 255 | 256 | ```sql 257 | CREATE EXTERNAL TABLE athena_db.procedures ( 258 | `Procedure_Id` string, 259 | `Procedure` string, 260 | `Category` string, 261 | `Price` integer, 262 | `Duration` integer, 263 | `Insurance` string, 264 | `Customer_Id` integer 265 | ) 266 | ROW FORMAT DELIMITED 267 | FIELDS TERMINATED BY ',' 268 | LINES TERMINATED BY '\n' 269 | STORED AS TEXTFILE 270 | LOCATION 's3://athena-datasource-{alias}/'; 271 | ``` 272 | 273 | 274 | - Your tables for Athena within editor should look similar to the following: 275 | 276 | ![Athena editor env created](images/env_created.png) 277 | 278 | - Now, lets quickly test the queries against the customers and procedures table by running the following two example queries below: 279 | 280 | ```sql 281 | SELECT * 282 | FROM athena_db.procedures 283 | WHERE insurance = 'yes' OR insurance = 'no'; 284 | ``` 285 | 286 | ![procedures query](images/procedure_query.png) 287 | 288 | 289 | ```sql 290 | SELECT * 291 | FROM athena_db.customers 292 | WHERE balance >= 0; 293 | ``` 294 | 295 | ![customers query](images/customer_query.png) 296 | 297 | 298 | - If tests were succesful, we can move to the next step. 299 | 300 | 301 | 302 | ### Step 3: Lambda Function Configuration 303 | - Create a Lambda function (Python 3.12) for the Bedrock agent's action group. We will call this Lambda function `bedrock-agent-txtsql-action`. 304 | 305 | ![Create Function](images/create_function.png) 306 | 307 | ![Create Function2](images/create_function2.png) 308 | 309 | - Copy the provided code from [here](https://github.com/build-on-aws/bedrock-agent-txt2sql/blob/main/function/lambda_function.py), or from below into the Lambda function. 310 | 311 | ```python 312 | import boto3 313 | from time import sleep 314 | 315 | # Initialize the Athena client 316 | athena_client = boto3.client('athena') 317 | 318 | def lambda_handler(event, context): 319 | print(event) 320 | 321 | def athena_query_handler(event): 322 | # Fetch parameters for the new fields 323 | 324 | # Extracting the SQL query 325 | query = event['requestBody']['content']['application/json']['properties'][0]['value'] 326 | 327 | print("the received QUERY:", query) 328 | 329 | s3_output = 's3://athena-destination-store-alias' # Replace with your S3 bucket 330 | 331 | # Execute the query and wait for completion 332 | execution_id = execute_athena_query(query, s3_output) 333 | result = get_query_results(execution_id) 334 | 335 | return result 336 | 337 | def execute_athena_query(query, s3_output): 338 | response = athena_client.start_query_execution( 339 | QueryString=query, 340 | ResultConfiguration={'OutputLocation': s3_output} 341 | ) 342 | return response['QueryExecutionId'] 343 | 344 | def check_query_status(execution_id): 345 | response = athena_client.get_query_execution(QueryExecutionId=execution_id) 346 | return response['QueryExecution']['Status']['State'] 347 | 348 | def get_query_results(execution_id): 349 | while True: 350 | status = check_query_status(execution_id) 351 | if status in ['SUCCEEDED', 'FAILED', 'CANCELLED']: 352 | break 353 | sleep(1) # Polling interval 354 | 355 | if status == 'SUCCEEDED': 356 | return athena_client.get_query_results(QueryExecutionId=execution_id) 357 | else: 358 | raise Exception(f"Query failed with status '{status}'") 359 | 360 | action_group = event.get('actionGroup') 361 | api_path = event.get('apiPath') 362 | 363 | print("api_path: ", api_path) 364 | 365 | result = '' 366 | response_code = 200 367 | 368 | 369 | if api_path == '/athenaQuery': 370 | result = athena_query_handler(event) 371 | else: 372 | response_code = 404 373 | result = {"error": f"Unrecognized api path: {action_group}::{api_path}"} 374 | 375 | response_body = { 376 | 'application/json': { 377 | 'body': result 378 | } 379 | } 380 | 381 | action_response = { 382 | 'actionGroup': action_group, 383 | 'apiPath': api_path, 384 | 'httpMethod': event.get('httpMethod'), 385 | 'httpStatusCode': response_code, 386 | 'responseBody': response_body 387 | } 388 | 389 | api_response = {'messageVersion': '1.0', 'response': action_response} 390 | return api_response 391 | ``` 392 | 393 | - Then, update the **alias** value for the `s3_output` variable in the python code above. After, select **Deploy** under **Code source** in the Lambda console. Review the code provided before moving to the next step. 394 | 395 | 396 | ![Lambda deploy](images/lambda_deploy.png) 397 | 398 | - Now, we need to apply a resource policy to Lambda that grants Bedrock agent access. To do this, we will switch the top tab from **code** to **configuration** and the side tab to **Permissions**. Then, scroll to the **Resource-based policy statements** section and click the **Add permissions** button. 399 | 400 | ![Permissions config](images/permissions_config.png) 401 | 402 | ![Lambda resource policy create](images/lambda_resource_policy_create.png) 403 | 404 | - Enter `arn:aws:bedrock:us-west-2:{aws-account-id}:agent/* `. ***Please note, AWS recommends least privilage so only the allowed agent can invoke this Lambda function***. A `*` at the end of the ARN grants any agent in the account access to invoke this Lambda. Ideally, we would not use this in a production environment. Lastly, for the Action, select `lambda:InvokeAction`, then ***Save***. 405 | 406 | ![Lambda resource policy](images/lambda_resource_policy.png) 407 | 408 | - We also need to provide this Lambda function permissions to interact with an S3 bucket, and Amazon Athena service. While on the `Configuration` tab -> `Permissions` section, select the Role name: 409 | 410 | ![Lambda role name 1](images/lambda_role1.png) 411 | 412 | - Select `Add permissions -> Attach policies`. Then, attach the AWS managed policies ***AmazonAthenaFullAccess***, and ***AmazonS3FullAccess*** by selecting, then adding the permissions. Please note, in a real world environment, it's recommended that you practice least privilage. 413 | 414 | ![Lambda role name 2](images/lambda_role2.png) 415 | 416 | - The last thing we need to do with the Lambda is update the configurations. Navigate to the `Configuration` tab, then `General Configuration` section on the left. From here select Edit. 417 | 418 | ![Lambda role name 2](images/lambda_config1.png) 419 | 420 | - Update the memory to **1024 MB**, and Timeout to **1 minute**. Scroll to the bottom, and save the changes. 421 | 422 | ![Lambda role name 2](images/lambda_config2.png) 423 | 424 | 425 | ![Lambda role name 3](images/lambda_config3.png) 426 | 427 | 428 | - We are now done setting up the Lambda function 429 | 430 | 431 | 432 | ### Step 4: Setup Bedrock agent and action group 433 | - Navigate to the Bedrock console. Go to the toggle on the left, and under **Builder tools** select ***Agents***, then ***Create Agent***. Provide an agent name, like `athena-agent` then ***Create***. 434 | 435 | ![agent create](images/agent_create.png) 436 | 437 | - For this next screen, agent description is optional. Use the default new service role. For the model, select **Anthropic Claude 3 Haiku**. Next, provide the following instruction for the agent: 438 | 439 | 440 | ```instruction 441 | You are a SQL developer creating queries for Amazon Athena. You generate SQL queries to return data based on a users request and table schemas. Here is how I want you to think step by step: 442 | 443 | 1. Query Decomposition and Understanding: 444 | - Analyze the user’s request to understand the main objective. 445 | - Break down reqeusts into sub-queries that can each address a part of the user's request, using the schema provided. 446 | 447 | 2. SQL Query Creation: 448 | - For each sub-query, use the relevant tables and fields from the provided schema. 449 | - Construct SQL queries that are precise and tailored to retrieve the exact data required by the user’s request. 450 | 451 | 3. Query Execution and Response: 452 | - Execute the constructed SQL queries against the Amazon Athena database. 453 | - Return the results exactly as they are fetched from the database, ensuring data integrity and accuracy. Include the query generated and results in the response. 454 | ``` 455 | 456 | It should look similar to the following: 457 | 458 | ![agent instruction](images/agent_instruction.png) 459 | 460 | - Scroll to the top, then select ***Save***. 461 | 462 | - Keep in mind that these instructions guide the generative AI application in its role as a SQL developer creating efficient and accurate queries for Amazon Athena. The process involves understanding user requests, decomposing them into manageable sub-queries, and executing these to fetch precise data. This structured approach ensures that responses are not only accurate but also relevant to the user's needs, thereby enhancing user interaction and data retrieval efficiency. 463 | 464 | 465 | - Next, we will add an action group. Scroll down to `Action groups` then select ***Add***. 466 | 467 | - Call the action group `query-athena`. In the `Action group type` section, select ***Define with API schemas***. For `Action group invocations`, set to ***Select an existing Lambda function***. For the Lambda function, select `bedrock-agent-txtsql-action`. 468 | 469 | - For the `Action group Schema`, we will choose ***Define with in-line OpenAPI schema editor***. Replace the default schema in the **In-line OpenAPI schema** editor with the schema provided below. You can also retrieve the schema from the repo [here](https://github.com/build-on-aws/bedrock-agent-txt2sql/blob/main/schema/athena-schema.json). After, select ***Add***. 470 | `(This API schema is needed so that the bedrock agent knows the format structure and parameters needed for the action group to interact with the Lambda function.)` 471 | 472 | ```schema 473 | { 474 | "openapi": "3.0.1", 475 | "info": { 476 | "title": "AthenaQuery API", 477 | "description": "API for querying data from an Athena database", 478 | "version": "1.0.0" 479 | }, 480 | "paths": { 481 | "/athenaQuery": { 482 | "post": { 483 | "description": "Execute a query on an Athena database", 484 | "requestBody": { 485 | "description": "Athena query details", 486 | "required": true, 487 | "content": { 488 | "application/json": { 489 | "schema": { 490 | "type": "object", 491 | "properties": { 492 | "Procedure ID": { 493 | "type": "string", 494 | "description": "Unique identifier for the procedure", 495 | "nullable": true 496 | }, 497 | "Query": { 498 | "type": "string", 499 | "description": "SQL Query" 500 | } 501 | } 502 | } 503 | } 504 | } 505 | }, 506 | "responses": { 507 | "200": { 508 | "description": "Successful response with query results", 509 | "content": { 510 | "application/json": { 511 | "schema": { 512 | "type": "object", 513 | "properties": { 514 | "ResultSet": { 515 | "type": "array", 516 | "items": { 517 | "type": "object", 518 | "description": "A single row of query results" 519 | }, 520 | "description": "Results returned by the query" 521 | } 522 | } 523 | } 524 | } 525 | } 526 | }, 527 | "default": { 528 | "description": "Error response", 529 | "content": { 530 | "application/json": { 531 | "schema": { 532 | "type": "object", 533 | "properties": { 534 | "message": { 535 | "type": "string" 536 | } 537 | } 538 | } 539 | } 540 | } 541 | } 542 | } 543 | } 544 | } 545 | } 546 | } 547 | ``` 548 | 549 | Your configuration should look like the following: 550 | 551 | 552 | ![ag create gif](images/action_group_creation.gif) 553 | 554 | 555 | 556 | - Now we will need to modify the **Advanced prompts**. While your still in edit mode, Scroll down to the advanced prompts section, and select `Edit`. 557 | 558 | ![ad prompt btn](images/advance_prompt_btn.png) 559 | 560 | 561 | - In the `Advanced prompts`, navigate to the **Orchestration** tab. Enable the `Override orchestration template defaults` option. `Activate orchestration template` should be enabled by default. Otherwise, enable it. 562 | 563 | - In the `Prompt template editor`, go to line 19-20, make a line space, then copy/paste the following prompt (**Make sure to update the alias values in the schemas first**): 564 | 565 | ```sql 566 | Here are the table schemas for the Amazon Athena database . 567 | 568 | 569 | 570 | CREATE EXTERNAL TABLE athena_db.customers ( 571 | `Cust_Id` integer, 572 | `Customer` string, 573 | `Balance` integer, 574 | `Past_Due` integer, 575 | `Vip` string 576 | ) 577 | ROW FORMAT DELIMITED 578 | FIELDS TERMINATED BY ',' 579 | LINES TERMINATED BY '\n' 580 | STORED AS TEXTFILE 581 | LOCATION 's3://athena-datasource-{alias}/'; 582 | 583 | 584 | 585 | CREATE EXTERNAL TABLE athena_db.procedures ( 586 | `Procedure_ID` string, 587 | `Procedure` string, 588 | `Category` string, 589 | `Price` integer, 590 | `Duration` integer, 591 | `Insurance` string, 592 | `Customer_Id` integer 593 | ) 594 | ROW FORMAT DELIMITED 595 | FIELDS TERMINATED BY ',' 596 | LINES TERMINATED BY '\n' 597 | STORED AS TEXTFILE 598 | LOCATION 's3://athena-datasource-{alias}/'; 599 | 600 | 601 | 602 | Here are examples of Amazon Athena queries . 603 | 604 | 605 | 606 | SELECT * FROM athena_db.procedures WHERE insurance = 'yes' OR insurance = 'no'; 607 | 608 | 609 | 610 | SELECT * FROM athena_db.customers WHERE balance >= 0; 611 | 612 | 613 | ``` 614 | 615 | - Here is a clip on configuring the requirements from above. 616 | ![adv prompt create gif](images/adv_prompt_creation.gif) 617 | 618 | 619 | - This prompt helps provide the agent an example of the table schema(s) used for the database, along with an example of how the Amazon Athena query should be formatted. Additionally, there is an option to use a [custom parser Lambda function](https://docs.aws.amazon.com/bedrock/latest/userguide/lambda-parser.html) for more granular formatting. 620 | 621 | - Scroll to the bottom and select the ***Save and exit***. Then, ***Save and exit*** one more time. 622 | 623 | 624 | 625 | ### Step 5: Create an alias 626 | - At the top, select **Save**, then **Prepare**. After, select **Save and exit**. Then, scroll down to the **Alias** section and select ***Create***. Choose a name of your liking, then create the alias. Make sure to copy and save your **AliasID**. Also, scroll to the top and save the **Agent ID** located in the **Agent overview** section. You will need this in step 7. Refer to the screenshots below. 627 | 628 | ***Alias Agent ID*** 629 | 630 | ![Create alias](images/create_alias.png) 631 | 632 | ***Agent ID*** 633 | 634 | ![Agent ARN2](images/agent_arn2.png) 635 | 636 | 637 | ## Step 6: Testing the Setup 638 | 639 | ### Testing the Bedrock Agent 640 | - In the test UI on the right, select **Prepare**. Then, enter prompts in the user interface to test your Bedrock agent. 641 | 642 | ![Agent test](images/agent_test.png) 643 | 644 | 645 | - Example prompts for Action Groups: 646 | 647 | 1. Show me all of the procedures in the imaging category that are insured. 648 | 649 | 2. Show me all of the customers that are vip, and have a balance over 200 dollars. 650 | 651 | 3. Return to me the number of procedures that are in the laboratory category. 652 | 653 | 4. Get me data of all procedures that were not insured, with customer names. 654 | 655 | 656 | ## Step 7: Setup and Run Streamlit App on EC2 (Optional) 657 | 1. **Obtain CF template to launch the streamlit app**: Download the Cloudformation template from [here](https://github.com/build-on-aws/bedrock-agent-txt2sql/blob/main/cfn/3-ec2-streamlit-template.yaml). This template will be used to deploy an EC2 instance that has the Streamlit code to run the UI. 658 | 659 | 660 | 2. **Edit the app to update agent IDs**: 661 | - Navigate to the EC2 instance management console. Under instances, you should see `EC2-Streamlit-App`. Select the checkbox next to it, then connect to it via `EC2 Instance Connect`. 662 | 663 | ![ec2 connect clip](images/ec2_connect.gif) 664 | 665 | - If you see a message that says **EC2 Instance Connect service IP addresses are not authorized**, then you will need to re-deploy the template and select the correct CIDR range for the EC2 based on the region you are in. This will allow you to cannect to the EC2 instance via SSH. By default, it is the allowed CIDR range for **us-west-2** region. However, if you are in the **us-east-1** region for example, the CIDR range will need to be **18.206.107.24/29** when deploying the AWS Cloudformation template. Additional CIDR ranges for each region can be found [here](https://raw.githubusercontent.com/joetek/aws-ip-ranges-json/refs/heads/master/ip-ranges-ec2-instance-connect.json). 666 | 667 | ![ec2 ssh error](images/ec2_ssh_error.gif) 668 | 669 | - Next, use the following command to edit the invoke_agent.py file: 670 | ```bash 671 | sudo vi app/streamlit_app/invoke_agent.py 672 | ``` 673 | 674 | - Press ***i*** to go into edit mode. Then, update the ***AGENT ID*** and ***Agent ALIAS ID*** values. 675 | 676 | ![file_edit](images/file_edit.png) 677 | 678 | - After, hit `Esc`, then save the file changes with the following command: 679 | ```bash 680 | :wq! 681 | ``` 682 | 683 | - Now, start the streamlit app by running the following command: 684 | ```bash 685 | streamlit run app/streamlit_app/app.py 686 | 687 | - You should see an external URL. Copy & paste the URL into a web browser to start the streamlit application. 688 | 689 | ![External IP](images/external_ip.png) 690 | 691 | 692 | - Once the app is running, please test some of the sample prompts provided. (On 1st try, if you receive an error, try again.) 693 | 694 | ![Running App ](images/running_app.png) 695 | 696 | Optionally, you can review the trace events in the left toggle of the screen. This data will include the rational tracing, invocation input tracing, and observation tracing. 697 | 698 | ![Trace events ](images/trace_events.png) 699 | 700 | 701 | ## Cleanup 702 | 703 | After completing the setup and testing of the Bedrock Agent and Streamlit app, follow these steps to clean up your AWS environment and avoid unnecessary charges: 704 | 1. Delete S3 Buckets: 705 | - Navigate to the S3 console. 706 | - Select the buckets "athena-datasource-alias" and "bedrock-agents-athena-output-alias". Make sure that both of these buckets are empty by deleting the files. 707 | - Choose 'Delete' and confirm by entering the bucket name. 708 | 709 | 2. Remove Lambda Function: 710 | - Go to the Lambda console. 711 | - Select the "bedrock-agent-txtsql-action" function. 712 | - Click 'Delete' and confirm the action. 713 | 714 | 3. Delete Bedrock Agent: 715 | - In the Bedrock console, navigate to 'Agents'. 716 | - Select the created agent, then choose 'Delete'. 717 | 718 | 4. Clean Up EC2 Environment: 719 | - Navigate to the EC2 management console. 720 | - Select the EC2 instance created, then delete. 721 | 722 | 723 | ## Security 724 | 725 | See [CONTRIBUTING](CONTRIBUTING.md#security-issue-notifications) for more information. 726 | 727 | ## License 728 | 729 | This library is licensed under the MIT-0 License.
