Creating a cluster subnet group - Amazon Redshift

Amazon Redshift will no longer support the use of Python UDFs after June 30, 2026. We will start enforcing it in phases. For more information on the details of Python end of life and migration options, see the blog post that was published on June 30, 2025.

Creating a cluster subnet group

The following procedure walks you through how to create a subnet group for a provisioned cluster. You must have at least one cluster subnet group defined to provision a cluster in a VPC.

To create a cluster subnet group for a provisioned cluster

  1. Sign in to the AWS Management Console and open the Amazon Redshift console at https://console.aws.amazon.com/redshiftv2/.

  2. On the navigation menu, choose Configurations, then choose Subnet groups. The list of subnet groups is displayed.

  3. Choose Create cluster subnet group to display the create page.

  4. Enter information for the subnet group, including which subnets to add.

  5. Choose Create cluster subnet group to create the group with the subnets that you chose.
