A node pool is a group of nodes that share the same configuration properties, such as instance types, operating systems, zones, labels, and taints. You can create multiple node pools with different configurations in a cluster. This lets you perform unified management on the nodes within each pool.
Create an edge node pool
Log on to the RDS console.
In the left navigation pane, click RDS Custom > Custom Container Clusters. In the top navigation bar, select a region.
On the ACK Edge Clusters page, click the ID of the target cluster.
On the Node Pools page, click Create Edge Node Pool.
On the Create Edge Node Pool page, configure the edge node pool.
Parameter
Description
Node Pool Name
The name must be 1 to 63 characters in length and can contain digits, underscores (_), and hyphens (-). The name must start with a letter, a Chinese character, or a digit.
Container Runtime
Edge 1.24 and later versions support only the containerd runtime.
Scale-out Mode
Currently, you can add nodes only using Manual Scale-out.
Node Configuration
The configuration of nodes in the node pool is the configuration of RDS Custom instances. For more information, see Create an RDS Custom instance.
NoteThe system automatically initializes and mounts the last data disk of each node. The data disk is mounted to /var/lib/container. The /var/lib/kubelet and /var/lib/containerd directories are mounted to the /var/lib/container directory.
Number Of Instances
The number of nodes (RDS Custom instances) that are automatically created when you create the node pool. The default value is 0, which indicates that no nodes are automatically created when the node pool is created.
After you confirm the configurations, click Pay Now to complete the payment.
View an edge node pool
Log on to the RDS console.
In the left navigation pane, click RDS Custom > Custom Container Clusters. In the top navigation bar, select a region.
On the ACK Edge Clusters page, click the ID of the target cluster.
On the Node Pools page, click the target node pool's ID to view its details.
Click the Basic Information tab to view details such as the node pool ID, container runtime, cloud-edge and inter-node network connectivity, pod network pattern, node labels, and taints.
You can click the Monitoring tab to view monitoring information for the node.
Scale out an edge node pool
Log on to the RDS console.
In the navigation pane on the left, click RDS Custom > Custom Container Clusters. In the top navigation bar, select a region.
On the ACK Edge Clusters page, click the target cluster ID.
On the Node Pools page, click Scale Out in the row of the target node pool.
On the Scale Out Node Pool page, specify the number of RDS Custom nodes and click OK.
You can click the ID of the target node pool to view the new nodes on the Basic Information tab.
Delete an edge node pool
To avoid affecting RDS Custom features, do not delete an associated edge node pool from the Container Service for Kubernetes (ACK) console or using ACK Edge APIs. You must delete the node pool from the RDS Custom console or using the relevant RDS Custom APIs.
Log on to the RDS console.
In the left navigation pane, click RDS Custom > Custom Container Clusters. In the top navigation bar, select a region.
On the ACK Edge Clusters page, click the ID of the target cluster.
On the Node Pools page, click Delete next to the target node pool.
On the Delete Node Pool page, click OK.
NoteIf the edge node pool contains edge nodes, you must first remove the edge nodes before you can delete the node pool.
