January 28, 2025	Announcement of requirement to access Google Kubernetes Engine clusters through DNS-based endpoints. See release note .	If you don't use Workflows to access GKE clusters, no action is required from you. For more information, in this document, see the January 28, 2025 section.

January 28, 2025

Effective May 2, 2025, Workflows will not support HTTP requests to the IP-based endpoints of Google Kubernetes Engine (GKE) cluster control planes. To ensure that your workflow functions as expected, you must access the DNS-based endpoints . As a best practice, we recommend that instead of making a direct HTTP call, you use the Kubernetes API connector in a workflow.

Scope and impact

If you don't use Workflows to access GKE clusters, no action is required from you.

As of May 2, 2025, new workflows are impacted; however, existing workflows will continue to function.

By August 1, 2025, any workflows that continue to make HTTP requests to the IP-based endpoints of GKE clusters might not function as expected.

Required action

Ensure that any workflows that access the IP-based endpoints of GKE clusters are modified to use the DNS-based endpoints instead by July 21, 2025. For more information, see HTTP requests to GKE .
