The Lambda is then connected to an API Gateway to allow user interface. 17 | 18 | **Functional Requirements:** 19 | 20 | Be able to query an RDS instance from within a AWS Lambda function without the use of VPC. 21 | 22 | **Performance Requirements:** 23 | 24 | Avoid performance issues caused by VPC configuration. 25 | 26 | **Recipes built on top of this recipe:** 27 | 28 | [How I Build a Scalable Crypto Exchange with AWS and web3.js](https://coderecipe.ai/architectures/95580531) 29 | 30 | ### Prerequisites 31 | 32 | Make sure you have AWS access key and secrete keys setup locally, following this video [here](https://www.youtube.com/watch?v=_f0d2pLJjiA) 33 | 34 | ### Download the code locally 35 | 36 | ``` 37 | git clone https://github.com/CodeRecipe-dev/LambdaToAuroraNoVPC 38 | ``` 39 | 40 | ### Deploy to the cloud 41 | 42 | ``` 43 | cd LambdaToAuroraNoVPC 44 | 45 | npm install serverless 46 | pip install -r requirements.txt 47 | 48 | serverless deploy --stage --dbUser 49 | ``` 50 | 51 | #### Create DB - Must be done before using app 52 | 53 | ``` 54 | sls invoke -f AuroraCRUD -d '{"body":{"eventType":"createTable"}}' -l --stage --dbUser 55 | ``` 56 | 57 | #### CRUD Operations 58 | 59 | ``` 60 | sls invoke -f AuroraCRUD -d '{"body":{"eventType":"saveRecord", "recordInfo": {"record_id": 1, "data": "hello"}}}' -l --stage --dbUser 61 | sls invoke -f AuroraCRUD -d '{"body":{"eventType":"getRecords"}}' -l --stage --dbUser 62 | sls invoke -f AuroraCRUD -d '{"body":{"eventType":"updateRecord", "recordInfo": {"record_id": 1, "data": "world"}}}' -l --stage --dbUser 63 | 64 | ``` -------------------------------------------------------------------------------- /handler.py: -------------------------------------------------------------------------------- 1 | import json 2 | import os 3 | import boto3 4 | from random import * 5 | import sql 6 | 7 | def handle_aurora_crud(event, context): 8 | request_body = event['body'] 9 | event_type = request_body['eventType'] 10 | databaseName = os.environ['DatabaseName'] 11 | awsSecretStoreArn = os.environ['AwsSecretStoreArn'] 12 | dbClusterOrInstanceArn = os.environ['DbClusterArn'] 13 | 14 | if event_type == "createTable": 15 | sql.create_table(databaseName, awsSecretStoreArn, dbClusterOrInstanceArn) 16 | return {"success": True, "message": "Created Table"} 17 | 18 | if event_type == "getRecords": 19 | records = sql.get_records(databaseName, awsSecretStoreArn, dbClusterOrInstanceArn) 20 | return {"success": True, "records": records} 21 | 22 | if event_type == "saveRecord": 23 | record_info = request_body['recordInfo'] 24 | record_info['record_id'] = randint(1,10000000) 25 | sql.create_record(databaseName, awsSecretStoreArn, dbClusterOrInstanceArn, record_info) 26 | return {"success": True, "message": "Saved Record", "record": record_info} 27 | 28 | if event_type == "updateRecord": 29 | record_info = request_body['recordInfo'] 30 | sql.update_record(databaseName, awsSecretStoreArn, dbClusterOrInstanceArn, record_info) 31 | return {"success": True, "message": "Updated Record"} -------------------------------------------------------------------------------- /index.html: -------------------------------------------------------------------------------- 1 | 2 | 3 | 4 | AWS Lambda to AWS RDS without VPC 5 | 6 | 7 | 15 |
