= Changing the Amazon Web Services instance type by using the AWS console
|
|
|
|
You can change the Amazon Web Services (AWS) instance type that your control plane machines use by updating the instance type in the AWS console.
|
|
|
|
.Prerequisites
|
|
|
|
* You have access to the AWS console with the permissions required to modify the EC2 Instance for your cluster.
|
|
* You have access to the {product-title} cluster as a user with the `cluster-admin` role.
|
|
|
|
.Procedure
|
|
|
|
. Open the AWS console and fetch the instances for the control plane machines.
|
|
|
|
. Choose one control plane machine instance.
|
|
|
|
.. For the selected control plane machine, back up the etcd data by creating an etcd snapshot. For more information, see "Backing up etcd".
|
|
|
|
.. In the AWS console, stop the control plane machine instance.
|
|
|
|
.. Select the stopped instance, and click *Actions* -> *Instance Settings* -> *Change instance type*.
|
|
|
|
.. Change the instance to a larger type, ensuring that the type is the same base as the previous selection, and apply changes. For example, you can change `m6i.xlarge` to `m6i.2xlarge` or `m6i.4xlarge`.
|
|
|
|
.. Start the instance.
|
|
|
|
.. If your {product-title} cluster has a corresponding `Machine` object for the instance, update the instance type of the object to match the instance type set in the AWS console.
|
|
|
|
. Repeat this process for each control plane machine.
