Change

Starting May 5, 2026, ACK will gradually stop resolving domains in the format {Cluster ID}.{region}.alicontainer.com. You must configure your own custom domains to continue using the Ingress service.

Impact

This change impacts the following cluster types:

• ACK managed clusters, ACK dedicated clusters, ACK Edge clusters, and ACK Lingjun clusters: Ingress rules that use an alicontainer.com domain will become unresolvable, making the associated backend services inaccessible via that domain.
• Distributed Cloud Container Platform for Kubernetes (ACK One) (GitOps): For ACK One fleet clusters using the default Argo CD domain, the domain will become unresolvable.
• ACK One (workflow clusters): For workflow clusters using the default ArgoServer domain, the domain will become unresolvable.

As of July 15, 2024, ACK already stopped providing alicontainer.com testing domains for newly created clusters. Clusters created after this date are not affected by this change. For details, see [Product Change] Discontinuation of Ingress testing domains for new clusters.
