= Configuring the {SMProductShortName} Operator to run on infrastructure nodes
|
|
|
|
This task should only be performed if the {SMProductShortName} Operator runs on an infrastructure node.
|
|
|
|
If the operator will run on a worker node, skip this task.
|
|
|
|
.Prerequisites
|
|
|
|
* The {SMProductShortName} Operator must be installed.
|
|
|
|
* One of the nodes comprising the deployment must be an infrastructure node. For more information, see "Creating infrastructure machine sets."
|
|
|
|
.Procedure
|
|
|
|
. List the operators installed in the namespace:
|
|
+
|
|
[source,terminal]
|
|
----
|
|
$ oc -n openshift-operators get subscriptions
|
|
----
|
|
|
|
. Edit the {SMProductShortName} Operator `Subscription` resource to specify where the operator should run:
|
|
+
|
|
[source,terminal]
|
|
----
|
|
$ oc -n openshift-operators edit subscription <name> <1>
|
|
----
|
|
<1> `<name>` represents the name of the `Subscription` resource. The default name of the `Subscription` resource is `servicemeshoperator`.
|
|
|
|
. Add the `nodeSelector` and `tolerations` to `spec.config` in the `Subscription` resource:
|
|
+
|
|
[source,yaml]
|

<1> Ensures that the operator pod is only scheduled on an infrastructure node.
|
|
<2> Ensures that the pod is accepted by the infrastructure node.
