Quick start
ACK Edge clusters let you manage edge computing resources within a single Kubernetes cluster and sink Alibaba Cloud capabilities to the edge to improve resource and application O&M efficiency and keep workloads stable. Follow these steps to get started.s let you manage edge computing resources within a single Kubernetes cluster. Follow these steps to get started.

|
Confirm the network environment and network plugin before creating an ACK Edge cluster. |
|
|
Before creating an ACK Edge cluster, activate ACK Edge for free. If ACK is not activated beforehand, cluster creation may fail.ACK Edge cluster. |
Activate Container Service for Kubernetes and authorize roles |
|
Create an ACK edge cluster in the ACK console, via API, or with Terraform. |
|
|
ACK Edge clusters manage multiple resource types, including data center nodes, ECS nodes across regions and cloud providers, and Edge Node Service (ENS) nodes. Add edge nodes to use these features. |

|
Edge scalability |
Network autonomy of edge nodes |
Configure edge node autonomy so applications keep running when an edge node disconnects from the cloud, without pod eviction or migration to other edge nodes. |
|
|
Application management |
In edge scenarios such as multi-region nodes and on-premises data centers, use YurtAppSets and DaemonSet update models for application management.
|
||
|
Cross-region communication |
Use the Raven add-on for cross-domain communication when cloud-edge resources are in different network domains. |
||
|
Offline O&M |
When edge node autonomy is enabled, the cloud control plane cannot modify edge workloads. Use offline O&M tools for emergency operations, including business rollback, resource configuration changes, and business updates. |
||
|
Elastic Cloud Resource |
Elasticity for ECS nodes, elastic container instances, and ACS instances |
When on-premises resources are insufficient, ACK Edge clusters scale out cloud nodes. Supported elastic resources include ECS-based node pools, elastic container instances, and ACS-based instances. |
|
|
Cloud Capability Sinking |
Observability |
ACK Edge clusters integrate monitoring, logging, and Node Problem Detector (NPD) to ensure edge service stability. |
|
|
Cloud-native AI suite |
ACK Edge clusters integrate with the cloud-native AI suite for the AI console, GPU sharing and scheduling, KServe, and Fluid acceleration. |
||
|
Image Acceleration |
Accelerate image pulling to reduce deployment time. ACK Edge clusters support on-demand and P2P image loading. |
||
|
Security management |
Improve security governance with cloud security capabilities. ACK Edge clusters support cluster auditing, custom Subject Alternative Names (SANs) for the API server certificate, Secret encryption, and RAM Roles for Service Accounts (RRSA). |
