Overview
When the service role CPU or memory is insufficient, you can increase the CPU or memory size by changing the configuration. This document introduces the relevant operations for changing instance configurations through the EMR on TKE console.
Note
Changing the configuration may cause running jobs to fail. Ensure that you perform this operation without impacting business operations.
During the configuration change process, resources may be preempted, causing pod reconstruction to fail and resulting in service unavailability. It is recommended to perform this operation during off-peak business hours.
Prerequisites
1. Pod resource configuration adjustments will be automatically billed item by item. Ensure sufficient account balance.
2. After the configuration of pay-as-you-go nodes is changed, the fees will be refrozen based on the latest configuration price. For more details, see EMR on TKE Billing Instructions > Purchase Instructions.
Directions
1. Log in to the EMR on TKE Console and click the Cluster ID/Name in the cluster list to enter the cluster details page.
2. On the cluster details page, select Cluster Services > A Certain Service, and enter the role management page.
3. On the role management page, select the service role that requires configuration changes and click Modify Configuration.
4. On the configuration adjustment page, confirm the relevant information for the configuration change, select the target CPU and memory configurations, and make sure to carefully read the important notice before checking Agree to Change Information.
5. After the fees are confirmed, click Confirm to adjust the configuration.
