    Edit Node Selection

    This section introduces how to edit the automatic node allocation for pod IP pools to automatically match appropriate nodes for the pod IP pool.

    When creating a pod IP pool, by default, its IP addresses can be allocated to pods on all nodes. You can set node selectors to restrict that only pods on nodes that meet specific conditions can use the IP addresses of the IP pool.

    Prerequisites

    • You should join a cluster and have the Cluster Network Resource Management permission within the cluster. For more information, refer to "Cluster Members" and "Cluster Roles".

    • KubeSphere Network should have been installed and enabled.

    Steps

    1. Log in to the KubeSphere web console with a user who has the Cluster Network Resource Management permission, and access your cluster.

    2. Click Network > Pod IP Pools in the left navigation pane.

    3. Click more on the right side of the pod IP pool you want to operate, and then select Edit YAML from the dropdown list.

    4. Enter the expression under the spec.nodeSelector parameter to filter nodes through custom expressions. For more information about expressions, please refer to Node Selector.

    Attention

    • The CIDR of the pod IP pool must not overlap with the CIDR of the nodes and the CIDR of the services.

    • When modifying related fields, you must clearly understand the impact of the operation, please proceed with caution.
