IOT Triggered Lambda
Instructions
Considering the serverless scripts, for triggering a lambda from IOT event all you have to do is add following code to your script
events:
- iot:
name: "IOTRule"
sql: "SELECT * FROM 'testtopic/#' where status = 'false'"
description: "This rule will select all published topic with status flag as false."
What the above script does is, It will trigger your lambda if any message published to IOT with topic as testtopic/. Now event that your lambda receives is what you send as message
Manual Approach Instructions
In Trigger configuration, select AWS IOT (aws devices iot) as trigger. Then in IoT type select Custom IoT rule. Now configure a Rule by selecting Create a new rule option. Give your Rule name and Rule description. Now the important part for Rule query statement Create a SQL statement for this rule. For example select * from "customtopic/#". Then select Enable Trigger to Enable the trigger now, or create it in a disabled state for testing (recommended). Best part of using this Add Trigger in Lambda approach is that Lambda will add the necessary permissions for AWS IoT to invoke your Lambda function from this trigger.
