= Adding node tuning to a machine pool
|
|
|
|
You can add tunings for compute, also called worker, nodes in a machine pool to control their configuration on {hcp-title-first} clusters.
|
|
|
|
[NOTE]
|
|
====
|
|
This feature is only supported on {hcp-title-first} clusters.
|
|

|
.Prerequisites
|
|
|
|
* You installed and configured the latest {product-title} (ROSA) CLI, `rosa`, on your workstation.
|
|
* You logged in to your Red{nbsp}Hat account by using the ROSA CLI.
|
|
* You created a {hcp-title-first} cluster.
|
|
* You have an existing machine pool.
|
|
* You have an existing tuning configuration.
|

.Procedure
|
|
|
|
. List all of the machine pools in the cluster:
|
|
+
|
|
[source,terminal]
|
|
----
|
|
$ rosa list machinepools --cluster=<cluster_name>
|
|
----
|
|
+
|
|
.Example output
|
|
+
|
|
[source,terminal]
|
|
----
|
|
ID AUTOSCALING REPLICAS INSTANCE TYPE [...] AVAILABILITY ZONES SUBNET VERSION AUTOREPAIR TUNING CONFIGS
|
|
workers No 2 m5.xlarge [...] us-east-1a N/A 4.12.14 Yes
|
|
db-nodes-mp No 2 m5.xlarge [...] us-east-1a No 4.12.14 Yes
|
|

|
|
|
|
. You can add tuning configurations to an existing or new machine pool.
|
|
|
|
.. Add tunings when creating a machine pool:
|
|
+
|
|
[source,terminal]
|
|
----
|
|
$ rosa create machinepool -c <cluster-name> <machinepoolname> --tuning-configs <tuning_config_name>
|
|
----
|
|
+
|
|
.Example output
|
|
[source,terminal]
|
|
----
|
|
? Tuning configs: sample-tuning
|
|
I: Machine pool 'db-nodes-mp' created successfully on hosted cluster 'sample-cluster'
|
|
I: To view all machine pools, run 'rosa list machinepools -c sample-cluster'
|
|
----
|
|
|
|
.. Add or update the tunings for a machine pool:
|
|
+
|
|
[source,terminal]
|
|
----
|
|
$ rosa edit machinepool -c <cluster-name> <machinepoolname> --tuning-configs <tuningconfigname>
|
|
----
|
|
+
|
|
.Example output
|
|
[source,terminal]
|
|
----
|
|
I: Updated machine pool 'db-nodes-mp' on cluster 'mycluster'
|
|
----
|
|
|
|
.Verification
|
|
|
|
. List the available machine pools in your cluster:
|
|
+
|
|
[source,terminal]
|
|
----
|
|
$ rosa list machinepools --cluster=<cluster_name>
|
|

|
.Example output
|
|

|
|
----
|
|
|
|
. Verify that the tuning config is included for your machine pool in the output. |
