Upgrading to New Node Pools
Upgraded node pools provide additional benefits beyond flexible payment options (pay-per-use and yearly/monthly). They also enhance configuration management and improve resource management efficiency and flexibility.
Why to Upgrade to the New Version?
- Flexible resource configuration: New node pools allow you to create pay-per-use nodes and select more cost-effective yearly/monthly nodes, depending on your needs.
- Multiple flavors available: You can easily filter different flavors for nodes, such as GPU nodes, based on CPU and memory parameters to meet the specific requirements of various service scenarios.
- Advanced auto scaling: New node pools can automatically scale and you can configure multiple scaling policies to optimize resource utilization for different service scenarios.
- Enhanced configuration management: New node pools offer improved customization options for Kubernetes parameters and provide better guidance to meet the complex requirements of managing containerized applications.
What Are Changes in the New Version?
- Yearly/Monthly nodes created in the new node pools cannot be manually scaled in. They can only be deleted or unsubscribed from.
- During auto scaling, only pay-per-use nodes are scaled in or out by default.
- You cannot create yearly/monthly nodes using the API for updating a node pool. Instead, you must increase or decrease them.
- By default, nodes created in new yearly/monthly node pools will be billed on a pay-per-use basis.
| Type | Before the Upgrade | After the Upgrade | |
|---|---|---|---|
| Pay-per-Use Node Pool | Yearly/Monthly Node Pool | ||
| Billing mode of nodes | Pay-per-use only | Yearly/Monthly only | Both pay-per-use and yearly/monthly |
| Node scale-out | Change the number of nodes in the node pool configuration. | Change the number of nodes in the node pool configuration. | Scale in or out the node pool. |
| Node scale-in |
|
| Pay-per-use nodes: Decrease them. Yearly/Monthly nodes: Unsubscribe from or remove them. |
| Upgrade | Upgrade the cluster to v1.21.11-r0, v1.23.9-r0, v1.25.4-r0, or later.
NOTE: After a node pool is upgraded, any nodes added using the API for updating a node pool will be pay-per-use by default. | ||
How to Upgrade to the New Version?
You need to upgrade your cluster to v1.21.11-r0, v1.23.9-r0, v1.25.4-r0, or later, and then perform the following operations to trigger the upgrade process of new node pool.
- Log in to the CCE console.
- Click the cluster name to access the cluster console. Choose Nodes in the navigation pane. In the right pane, click the Node Pools tab.
- Click Scaling in the Operation column of the target node pool. In the displayed dialog box, click Upgrade Now.
