$ oc edit machineset <machineset> -n openshift-machine-api
You can modify a compute machine set, such as adding labels, changing the instance type, or changing block storage.
If you need to scale a compute machine set without making other changes, see Manually scaling a compute machine set. |
To make changes to a compute machine set, edit the MachineSet
YAML. Then, remove all machines associated with the compute machine set by deleting each machine or scaling down the compute machine set to 0
replicas. Then, scale the replicas back to the desired number. Changes you make to a compute machine set do not affect existing machines.
If you need to scale a compute machine set without making other changes, you do not need to delete the machines.
By default, the OKD router pods are deployed on workers. Because the router is required to access some cluster resources, including the web console, do not scale the compute machine set to |
Install an OKD cluster and the oc
command line.
Log in to oc
as a user with cluster-admin
permission.
Edit the compute machine set by running the following command:
$ oc edit machineset <machineset> -n openshift-machine-api
Scale down the compute machine set to 0
by running one of the following commands:
$ oc scale --replicas=0 machineset <machineset> -n openshift-machine-api
Or:
$ oc edit machineset <machineset> -n openshift-machine-api
You can alternatively apply the following YAML to scale the compute machine set:
|
Wait for the machines to be removed.
Scale up the compute machine set as needed by running one of the following commands:
$ oc scale --replicas=2 machineset <machineset> -n openshift-machine-api
Or:
$ oc edit machineset <machineset> -n openshift-machine-api
You can alternatively apply the following YAML to scale the compute machine set:
|
Wait for the machines to start. The new machines contain changes you made to the compute machine set.
