| January 28, 2025 | Announcement of requirement to access Google Kubernetes Engine clusters through DNS-based endpoints. See [release note](https://docs.cloud.google.com/workflows/docs/release-notes#January_28_2025). | 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](https://docs.cloud.google.com/workflows/docs/service-announcements#2025-01-28) section. |

## January 28, 2025

Effective **May 2, 2025** , Workflows will not support
[HTTP requests](https://docs.cloud.google.com/workflows/docs/http-requests) to the
[IP-based endpoints](https://docs.cloud.google.com/kubernetes-engine/docs/reference/rest/v1/projects.locations.clusters#ipendpointsconfig)
of Google Kubernetes Engine (GKE) cluster control planes. To ensure that your
workflow functions as expected, you must access the
[DNS-based endpoints](https://docs.cloud.google.com/kubernetes-engine/docs/reference/rest/v1/projects.locations.clusters#dnsendpointconfig).
As a best practice, we recommend that instead of making a direct HTTP call, you
use the [Kubernetes API connector](https://docs.cloud.google.com/workflows/docs/access-kubernetes-api) 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** .

[HTTP requests to GKE](https://docs.cloud.google.com/workflows/docs/issues#gke-calls).
