Changing Cluster Scale
|
|
======================
|
|
|
|
Scenario
|
|
--------
|
|
|
|
CCE allows you to change the number of nodes managed in a cluster.
|
|
|
|
Notes and Constraints
|
|
---------------------
|
|
|
|
- This function is supported for clusters of v1.15 and later versions.
|
|
- Starting from v1.15.11, the number of nodes in a cluster can be changed to 2000. The number of nodes in a single master node cannot be changed to 1000 or more.
|
|
- Currently, a cluster can only be scaled out to a larger specification, but cannot be scaled in.
|
|
- During the specifications change, master nodes will be powered off and on, and the cluster cannot run properly. Perform the change during off-peak hours.
|
|
- Changing the cluster scale does not affect the services running in the cluster. However, the control plane (master nodes) will be interrupted for a short period of time. You are advised not to perform any other operations (such as creating workloads) during the change.
|
|
- Change failures will trigger a cluster rollback to the normal state. If the rollback fails, submit a service ticket.
|
|
|
|
Procedure
|
|
---------
|
|
|
|
#. Log in to the CCE console. In the navigation pane, choose **Clusters**.
|
|
|
|
#. Click |image1| next to the cluster whose specifications need to be changed.
|
|
|
|
#. On the page displayed, select a new flavor for **Target Flavor** as required.
|
|
|
|
#. Click **OK**.
|
|
|
|
You can click **Operation Records** in the upper left corner to view the cluster change history. The status changes from **Executing** to **Successful**, indicating that the cluster specifications are successfully changed.
