Updating a Node Pool

Updated on 2024-01-26 GMT+08:00

Constraints

  • When editing the resource tags of the node pool. The modified configuration takes effect only for new nodes. To synchronize the configuration to the existing nodes, manually reset the existing nodes.
  • Updates of kubernetes labels and taints are automatically synchronized to existing nodes. You do not need to reset nodes.

Updating a Node Pool

  1. Log in to the CCE console.
  2. Click the cluster name to access the cluster console. Choose Nodes in the navigation pane and click the Node Pools tab on the right.
  3. Click Update next to the name of the node pool you will edit. Configure the parameters in the displayed Update Node Pool page.

    Basic Settings
    Table 1 Basic settings

    Parameter

    Description

    Node Pool Name

    Name of the node pool.

    Nodes

    Modify the number of nodes based on service requirements.

    Auto Scaling

    This function is disabled by default.

    After you enable autoscaler by clicking , nodes in the node pool are automatically created or deleted based on service requirements.

    • Maximum Nodes and Minimum Nodes: You can set the maximum and minimum number of nodes to ensure that the number of nodes to be scaled is within a proper range.
    • Node Pool Priority: indicates the priority of a node pool for a scale-out. A larger value indicates a higher priority. For example, the node pool with priority 4 is scaled out prior to the one with priority 1. If the priorities of multiple node pools are set to the same value, these node pools are not prioritized and they will be scaled out by following the rule of maximizing resource utilization.

      After the priority is changed, the modification takes effect within 1 minute.

    • Cooldown Period: Enter a period, in minutes. It specifies a period during which the nodes added in the current node pool cannot be scaled in.

    To ensure the proper running of AS, install the autoscaler.

    Advanced Settings
    Table 2 Advanced settings

    Parameter

    Description

    Kubernetes Label

    A Kubernetes label is a key-value pair added to a Kubernetes object (such as a pod). After specifying a label, click Add. A maximum of 20 labels can be added.

    Labels can be used to distinguish nodes. With workload affinity settings, container pods can be scheduled to a specified node. For more information, see Labels and Selectors.

    NOTE:

    After a Kubernetes label is modified, the inventory nodes in the node pool are updated synchronously.

    Taint

    This field is left blank by default. You can add taints to configure node anti-affinity. A maximum of 20 taints are allowed for each node. Each taint contains the following parameters:
    • Key: A key must contain 1 to 63 characters, starting with a letter or digit. Only letters, digits, hyphens (-), underscores (_), and periods (.) are allowed. A DNS subdomain name can be used as the prefix of a key.
    • Value: A value must start with a letter or digit and can contain a maximum of 63 characters, including letters, digits, hyphens (-), underscores (_), and periods (.).
    • Effect: Available options are NoSchedule, PreferNoSchedule, and NoExecute.

    For details, see Managing Node Taints.

    NOTE:

    After a taint is modified, the existing nodes in the node pool are updated synchronously.

    Edit key pair

    Only node pools that use key pairs for login support key pair editing. You can select another key pair.

    NOTE:

    The edited key pair automatically takes effect on newly added nodes. For existing nodes, manually reset the nodes for the modification to take effect.

  4. After the configuration, click OK.

    After the node pool parameters are updated, go to the Nodes page to check whether the node to which the node pool belongs is updated. You can reset the node to synchronize the configuration updates for the node pool.
