Container Service for Kubernetes (ACK) allows you to use a node pool to manage multiple nodes in a cluster as a group. For example, you can centrally manage the labels and taints of the nodes in a node pool. This topic describes how to create a node pool that consists of Windows nodes in the ACK console.
- An ACK cluster is created. For more information, see Create a managed Kubernetes cluster.
- The Kubernetes version of the cluster is later than V1.9.
A Windows node pool supports only Flannel as the network plug-in and does not support Terway.
- By default, a cluster can contain at most 100 nodes. To increase the quota,Submit a ticket.
When you add an Elastic Compute Service (ECS) instance to a node pool, make sure that the ECS instance is associated with an elastic IP address (EIP) or a NAT gateway is configured for the virtual private cloud (VPC) where the ECS instance is deployed. In addition, make sure that the ECS instance can access the Internet. Otherwise, you cannot add the ECS instance.
- Windows node pools support Windows Server 2019 and Windows Server 1909 Core.
- Log on to the ACK console.
- In the left-side navigation pane of the ACK console, click Clusters.
- On the Clusters page, find the cluster that you want to manage and click the name of the cluster or click Details in the Actions column. The details page of the cluster appears.
- In the left-side navigation pane of the details page, choose .
- In the upper-right corner of the Node Pools page, click Create Node Pool. In the upper-right corner of the Node Pools page, you can also click Create Managed Node Pool to create a managed node pool, or click Configure Auto Scaling to create an auto-scaling node pool.
- In the Create Node Pool dialog box, configure the node pool. For more information about the parameters, see Create a managed Kubernetes cluster. The following list describes some of the parameters.
- Quantity: Specify the initial number of nodes in the node pool. If you do not want to add nodes to the pool, set this parameter to 0.
- Operating System: Select a Windows operating system.
- Node Label: Add labels to the nodes in the node pool.
- ECS Label: Add labels to the ECS instances.
- Click Confirm Order. On the Node Pools page, if the state of the node pool is Initializing, it indicates that the node pool is being created. After the node pool is created, the state of the node pool changes to Active.
