Amazon EventBridge Tutorial: Creating a Basic Rule

Introduction

Amazon EventBridge is a serverless event bus that makes it easy to route events between your applications and services. In this tutorial, we will show you how to create a basic rule that routes events to a Lambda function.

Prerequisites

To complete this tutorial, you will need the following:

• An AWS account
• The AWS CLI
• A Lambda function

Step 1: Create an EventBridge rule

To create an EventBridge rule, you can use the AWS CLI. The following command will create a rule that routes all events from the my-event-source event source to the my-lambda-function Lambda function:

``` aws events put-rule --name my-rule --event-pattern '{"source": ["my-event-source"]}' --targets '{"Id": "MyTarget", "Arn": "arn:aws:lambda:us-east-1:123456789012:function:my-lambda-function"}' ```

Step 2: Test the rule

To test the rule, you can use the AWS CLI to send a test event to the event source. The following command will send a test event to the my-event-source event source:

``` aws events put-events --entries '{"Source": "my-event-source", "Detail": "Hello, world!"}' ```

Step 3: View the rule in the console

You can view the rule in the AWS console by going to the EventBridge console and clicking on the Rules tab. The rule will be listed in the table of rules.

Conclusion

In this tutorial, we showed you how to create a basic EventBridge rule. You can use this rule to route events to any Lambda function or other AWS service.
