AWS DynamoDB Streams¶

The IntegrationSource supports the Amazon Web Services (AWS) DynamoDB Streams service, through its aws.ddbStreams property.

Amazon credentials¶

There are two options for authenticating to AWS.

Access key and secret¶

To use an IAM User access key and secret, create a Kubernetes Secret in the namespace of the resource. The Secret can be created like:

kubectl -n <namespace> create secret generic my-secret --from-literal=aws.accessKey=<accessKey> --from-literal=aws.secretKey=<secretKey>

Then in the IntegrationSource .spec.aws.auth section reference the Secret like this:

      auth:
        secret:
          ref:
            name: "my-secret"

Pod Default Credentials¶

If you are using IRSA or Pod Identity, you can create a Kubernetes ServiceAccount and associate it with an AWS IAM role. Then in the IntegrationSource .spec.aws.auth section specify the name of the ServiceAccount. This will assign the ServiceAccount to the Deployment resource created for the IntegrationSource.

      auth:
        serviceAccountName: "my-service-account"

AWS DynamoDB Streams Example¶

Below is an IntegrationSource to receive events from Amazon DynamoDB Streams.

apiVersion: sources.knative.dev/v1alpha1
kind: IntegrationSource
metadata:
  name: integration-source-aws-ddb
  namespace: knative-samples
spec:
  aws:
    ddbStreams:
      table: "my-table"
      region: "eu-north-1"
    auth:
      secret:
        ref:
        name: "my-secret"
  sink:
    ref:
      apiVersion: eventing.knative.dev/v1
      kind: Broker
      name: default

Inside of the aws.ddbStreams object we define the name of the table and its region. The credentials for the AWS service are referenced from the my-secret Kubernetes Secret
