Scaling a Node Pool

You can specify a specification in a node pool for scaling.

The default node pool does not support scaling. Use Creating a Node to add a node.

1. Log in to the CCE console.
2. Click the cluster name to access the cluster console. Choose Nodes in the navigation pane. In the right pane, click the Node Pools tab.
3. Choose Scaling next to the target node pool.
4. In the displayed Node Pool Scaling window, configure scaling parameters.
   • Add or reduce nodes for scaling.
   • Use the selected flavor to increase or decrease the number of nodes.
   • Select a billing mode only when adding nodes.
     • Yearly/Monthly

       You must specify the required duration if Yearly/Monthly is selected. You can choose whether to select Auto-renew based on site requirements. Your order will automatically renew on a monthly or yearly basis, depending on if you purchased by month or by year.

     • Pay-per-use

       Resources will be billed based on usage duration. You can provision or delete resources at any time.

   • Configure the number of nodes to be added or deleted.
     • When scaling out a node pool, make sure that the total number of nodes, both existing and new, does not exceed the management scale of the current cluster.
     • When scaling in a node pool, make sure that the number of nodes to be removed does not exceed the number of nodes currently in the pool.

       Scaling in can result in the unavailability of resources associated with a node, such as local storage and workloads that were scheduled to that node. Exercise caution when performing this operation to avoid impact on running services.
