= Scaling worker nodes using the CLI
|
|
|
|
[role="_abstract"]
|
|
Edit a machine pool to scale the number of worker nodes in that specific machine pool by using {rosa-cli}.
|
|
|
|
.Procedure
|
|
|
|
. Run the following command to see the default machine pool that is created with each cluster:
|
|
+
|
|
[source,terminal]
|
|
----
|
|
$ rosa list machinepools --cluster=<cluster-name>
|
|
----
|
|
+
|
|
*Example output*:
|
|
+
|
|
[source,terminal]
|
|
----
|
|
ID AUTOSCALING REPLICAS INSTANCE TYPE LABELS TAINTS AVAILABILITY ZONES
|
|
Default No 2 m5.xlarge us-east-1a
|
|
----
|
|
|
|
. To scale the default machine pool out to a different number of nodes, run the following command:
|
|
+
|
|
[source,terminal]
|
|
----
|
|
$ rosa edit machinepool --cluster=<cluster-name> --replicas=<number-nodes> <machinepool-name>
|
|
----
|
|
+
|
|
*For example*:
|
|
+
|
|
[source,terminal]
|
|
----
|
|
$ rosa edit machinepool --cluster=my-rosa-cluster --replicas 3 Default
|
|
----
|
|
|
|
. Run the following command to confirm that the machine pool has scaled:
|
|
+
|
|
[source,terminal]
|
|
----
|
|
$ rosa describe cluster --cluster=<cluster-name> | grep Compute
|
|
----
|
|
+
|
|
*For example*:
|
|
+
|
|
[source,terminal]
|
|
----
|
|
$ rosa describe cluster --cluster=my-rosa-cluster | grep Compute
|
|
----
|
|
+
|
|
*Example output*:
|
|
+
|
|
[source,terminal]
|
|
----
|

- Compute (Autoscaled): 2-4
|
