= Adding instance types
|
|
|
|
|
|
After a machine pool is created, the instance type cannot be changed. To add a different instance type for worker nodes, you must create a new machine pool for the additional instance type.
|
|
|
|
.Procedure
|
|
|
|
. To add an instance type with a new machine pool, enter the following command:
|
|
+
|
|
[source,terminal]
|
|
----
|
|
$ rosa create machinepool --cluster=<cluster-name> <machinepool_ID> --instance-type=<type>
|
|
----
|
|
+
|
|
This example creates a new machine pool with the instance type `m5.2x.large`, 2 replicas, and labels on a cluster named `mycluster`:
|
|
+
|
|
[source,terminal]
|
|
----
|
|
$ rosa create machinepool --cluster=mycluster db-nodes-large-mp --replicas=2 --labels=app=db,tier=backend --instance-type=m5.2xlarge
|
|

[NOTE]
|
|
====
|
|
For a complete list of supported instance types, see the _Policies and Service Definition_.

. To verify that the machine pool was created with the instance type, enter the following command:

|
|
[source,terminal]
|
|
----
|
|
$ rosa list machinepools --cluster=<cluster_name>
