How to invoke a REST API when an object arrives on S3?-CodePudding

S3 can be configured to invoke lambda when an object arrives in it.

Is it possible to invoke a REST API (endpoint of a microservice running in EKS) when an object arrives in S3?

From November 2021 is possible to integrate S3 with Amazon EventBridge. So you can create an EventBridge rule which is triggered on bucket object creation and has API destination as a target.

For this, the option Bucket Properties -> Amazon EventBridge -> "Send notifications to Amazon EventBridge for all events in this bucket" should be enabled.

Then, on EventBridge create the rule with an event pattern like this:

{
  "source": ["aws.s3"],
  "detail-type": ["Object Created"],
  "detail": {
    "bucket": {
      "name": ["<my-bucket-name>"]
    }
  }
}

And configure the target as API destination endpoint (configure http method, endpoint, authorization).

You can set up an SNS topic as a target for the event from S3. In the SNS topic, you can add an HTTP/s subscriber, which can be your API endpoint.

Have the Lambda hit the REST API for you.
