Container Service for Kubernetes (ACK) enables centralized management of nodes in a node pool. For example, you can centrally manage the labels and taints that are attached to nodes in a node pool. This topic describes how to create a node pool in the ACK console.

Prerequisites

  • An ACK cluster is created. For more information, see Create an ACK cluster.
  • The Kubernetes version must be V1.9 or later.
Notice
  • By default, you can deploy up to 100 nodes in each cluster. To increase the quota, submit a ticket. Submit a ticket.
  • Before you add an existing Elastic Compute Service (ECS) instance deployed in a Virtual Private Cloud (VPC) network, make sure that an Elastic IP address is attached to the ECS instance, or a Network Address Translation (NAT) gateway is deployed in the same VPC network. In addition, you must make sure that the corresponding node can access the public network. Otherwise, you fail to add the ECS instance.

Procedure

  1. Log on to the ACK console.
  2. In the left-side navigation pane, choose Clusters > Clusters.
  3. Find the target cluster, click Node Pools in the Actions column.
    Node pools
  4. In the upper-right corner of the Node Pools page, click Create Node Pool.
  5. On the Create Node Pool page, configure the parameters for the node pool.
    Parameters
    For more information about the parameters, see Create an ACK cluster. The following list describes some of the parameters:
    • Quantity: Specify the number of nodes that you want to add to the node pool. If you do not want to add nodes to the pool, set this parameter to 0.
    • Operating System: Select Windows.
    • Node Label: Attach labels to the nodes in the pool.
    • ECS Label: Attach labels to the ECS instances.
  6. Click OK.
    On the Node Pools page, the status of the node pool displays Initializing. This means that the node pool creation is in progress. After the creation is complete, the status of the node pool changes to Active.nodepool

What to do next

After the node pool is created, go to the Node Pools page, click Details in the Actions column to view the node pool details. You can also click Scale Out to scale out the node pool.
