Cluster and Node Pool Configurations

Check Items

Check whether the nic-max-above-warm-target value configured for the network component of the current cluster exceeds the maximum value allowed.

Solution

Determine the scope of impact based on the error information. For example:

configuration check failed: [nodepool id(1786cd55-xxxx-xxxx-aac8-0255ac100095): [eni/nic-max-above-warm-target] should be less than or equal to 256, nodepool id(master): [eni/nic-max-above-warm-target] should be less than or equal to 256]. Please make corrections at settings

This error information indicates that there are two abnormal nic-max-above-warm-target settings:

• nodepool id(1786cd55-xxxx-xxxx-aac8-0255ac100095) indicates that the node pool with the ID 1786cd55-xxxx-xxxx-aac8-0255ac100095 has an abnormal configuration.
• nodepool id(master) indicates that the cluster has an abnormal configuration.

Scenario 1: Abnormal node pool configuration

To fix this issue, perform the following operations:

1. Log in to the CCE console and click the cluster name to access the cluster console. In the navigation pane, choose Nodes.
2. Locate the affected node pool and choose More > Manage.
3. In Networking Components, set the nic-max-above-warm-target value to a maximum of 256.

   

4. Click OK.

Scenario 2: Abnormal cluster configuration

To fix this issue, perform the following operations:

1. Log in to the CCE console and click the cluster name to access the cluster console. In the navigation pane, choose Settings.
2. Click the Network tab and set the Threshold for Unbinding Pre-bound Container ENIs value to a maximum of 256.

   

3. Click Confirm Configuration.
