Configure GCP for a Google Cloud Storage sink connector

To be able to sink data from Apache Kafka® to Google Cloud Storage via the dedicated Aiven connector, you need to perform the following steps in the GCP console:

Create the Google Cloud Storage (GCS) bucket

You can create the GCS bucket using the dedicated Google cloud console page. When creating the bucket, specify bucket name and location, the other settings can be left as default.

Create a Google service account and generate a JSON service key

Follow the instructions to:

  • create a Google service account
  • create a JSON service key

The JSON service key will be used in the connector configuration

Grant the service account access to the GCS bucket

Navigate in the GCS bucket detail page, in the Permissions tab and grant access to the newly created service account to the bucket. The following object permissions must be enabled in the bucket:

  • storage.objects.create
  • storage.objects.delete (needed for overwriting, for example on re-processing)

The connector should be granted these permissions via a custom role or the standard role Storage Legacy Bucket Writer. You also need to ensure the bucket doesn't have a retention policy that prohibits overwriting.
