Edit a Node Pool

Resize a provisioned cluster by changing size of the node pool.

Prerequisites

Before you start this procedure, log in to the Tanzu Mission Control console and make sure you have the appropriate permissions.

• To edit a node pool, you must be associated with the cluster.edit role for the cluster.
• To view the node pools for a cluster, you must have managementcluster.get permission.

For more information about adding permissions to custom roles, see Create a Custom Access Role.

Procedure

1. In the Tanzu Mission Control console, navigate to the cluster whose node pool you want to edit.
2. On the cluster detail page, click the Node pools tab.
3. Click to expand the node pool you want to edit.
4. Click Edit.
5. Make the desired changes.
   You can modify the following settings in your node pool.

   • number of worker nodes
   • instance type
   • storage class (for Tanzu Kubernetes clusters running in vSphere)

   However, you cannot modify the other aspects of the node pool after it is created.
6. Click Save.

Results

If you decrease the number of nodes in the node pool, Tanzu Mission Control removes the additional nodes and allows the cluster to redistribute the workloads running on the nodes as necessary.

If you increase the number of nodes in the node pool, Tanzu Mission Control provisions the necessary resources and then launches the additional nodes.
