Terraform: A Deep Dive into AWS IoT Core Provisioning
Terraform, an infrastructure as code (IaC) tool, enables you to define both cloud and on-premises resources in human-readable configuration files that you can version, reuse, and share.
Setting up an AWS IoT Thing
First, let’s provision an IoT Thing, which represents a device or a logical entity in AWS IoT Core.
resource "aws_iot_thing" "example_thing" {
name = "MyIoTThing"
}This snippet creates an IoT Thing named “MyIoTThing”. Things in AWS IoT Core are the central entities that represent your devices in the cloud.
Creating an IoT Policy
Next, we define an IoT Policy. Policies control access to AWS IoT resources.
resource "aws_iot_policy" "example_policy" {
name = "MyIoTPolicy"
policy = <<EOF
{
"Version": "2012-10-17",
"Statement": [{
"Action": [
"iot:Connect",
"iot:Publish",
"iot:Subscribe",
"iot:Receive"
],
"Effect": "Allow",
"Resource": "*"
}]
}
EOF
}This policy allows devices to connect, publish, subscribe, and receive messages from any topic.
Attaching Policy to Thing
For the Thing to interact with AWS IoT Core under the defined policy, we attach the policy to the Thing.
resource "aws_iot_policy_attachment" "example_attach" {
policy = aws_iot_policy.example_policy.name
target = aws_iot_thing.example_thing.arn
}This binds the policy to the Thing, specifying what the Thing is authorized to do.
AWS CDK Version 2: Building IoT Applications
The AWS Cloud Development Kit (CDK) is a software development framework for defining cloud infrastructure in code and provisioning it through AWS CloudFormation. It provides high-level components called constructs that preconfigure cloud resources with sensible defaults.
Setting up the Environment
We begin by initializing a new CDK app and installing necessary packages:
mkdir iot-core-app && cd iot-core-app
cdk init app — language typescript
npm install @aws-cdk/aws-iot @aws-cdk/aws-lambdaThis sets up a new CDK project and installs the IoT and Lambda packages.
Defining a Lambda Function for IoT Data Processing
Let’s create a Lambda function that will process IoT messages. We assume you have a Lambda function code ready in the lambda directory.
import * as lambda from 'aws-cdk-lib/aws-lambda';
import { Construct } from 'constructs';
export class IoTProcessingFunction extends Construct {
public readonly handler: lambda.Function;
constructor(scope: Construct, id: string) {
super(scope, id);
this.handler = new lambda.Function(this, 'IoTMessageHandler', {
runtime: lambda.Runtime.NODEJS_14_X,
handler: 'index.handler',
code: lambda.Code.fromAsset('lambda'),
});
}
}This construct defines a Node.js Lambda function that handles IoT messages.
Creating an IoT Rule to Trigger the Lambda Function
Next, we create an IoT rule that triggers the Lambda function whenever a message is published to a specific MQTT topic.
import * as iot from 'aws-cdk-lib/aws-iot';
import { IoTProcessingFunction } from './iot-processing-function';
import { Stack, StackProps } from 'aws-cdk-lib';
import { Construct } from 'constructs';
class IoTCoreStack extends Stack {
constructor(scope: Construct, id: string, props?: StackProps) {
super(scope, id, props);
const processingFunction = new IoTProcessingFunction(this, 'ProcessingFunction');
new iot.CfnTopicRule(this, 'IoTTopicRule', {
ruleName: 'ProcessIoTMessages',
topicRulePayload: {
actions: [{
lambda: {
functionArn: processingFunction.handler.functionArn
}
}],
sql: "SELECT * FROM 'iot/topic'",
awsIotSqlVersion: '2016-03-23',
ruleDisabled: false
}
});
}
}
const app = new cdk.App();
new IoTCoreStack(app, 'IoTCoreExample');This code snippet defines an IoT rule named ProcessIoTMessages that triggers the previously defined Lambda function whenever messages are published to 'iot/topic'. It showcases the powerful integration capabilities of AWS
