Trigger Specification

This specification describes the aws-sqs-queue trigger that scales based on an AWS SQS Queue.

triggers:
- type: aws-sqs-queue
  metadata:
    # Required: queueURL
    queueURL: https://sqs.eu-west-1.amazonaws.com/account_id/QueueName
    queueLength: "5"  # Default: "5"
    # Required: awsRegion
    awsRegion: "eu-west-1" 
    identityOwner: pod | operator # Optional. Default: pod

Parameter list:

  • queueURL - Full URL for the SQS Queue
  • queueLength - Target value for ApproximateNumberOfMessages in the SQS Queue
  • awsRegion - AWS Region for the SQS Queue
  • identityOwner - Receive permissions on the SQS Queue via Pod Identity or from the KEDA operator itself (see below).

When identityOwner set to operator - the only requirement is that the Keda operator has the correct IAM permissions on the SQS queue. Additional Authentication Parameters are not required.

Authentication Parameters

These parameters are relevant only when identityOwner is set to pod.

You can use TriggerAuthentication CRD to configure the authenticate by providing either a role ARN or a set of IAM credentials.

Pod identity based authentication:

  • podIdentity.provider needs to be set to either aws-kiam or aws-eks on the TriggerAuthentication and the pod/service account must be configured correctly for your pod identity provider.

Role based authentication:

  • awsRoleArn - Amazon Resource Names (ARNs) uniquely identify AWS resource

Credential based authentication:

  • awsAccessKeyID - Id of the user
  • awsSecretAccessKey - Access key for the user to authenticate with

The user will need access to read properties from the specified AWS SQS queue.
