= Overriding the priority class name for catalog source pods
|
|
|
|
.Prerequisites
|
|
|
|
* A `CatalogSource` object of source type `grpc` with `spec.image` is defined.
|
|
ifdef::openshift-dedicated,openshift-rosa,openshift-rosa-hcp[]
|
|
* You have access to the cluster as a user with the `dedicated-admin` role.
|
|
endif::openshift-dedicated,openshift-rosa,openshift-rosa-hcp[]
|
|
|
|
.Procedure
|
|
|
|
* Edit the `CatalogSource` object and add or modify the `spec.grpcPodConfig` section to include the following:
|
|
+
|
|
[source,yaml]
|
|
----
|
|
grpcPodConfig:
|
|
priorityClassName: <priority_class>
|
|
----
|
|
+
|
|
where `<priority_class>` is one of the following:
|
|
+
|
|
--
|
|
* One of the default priority classes provided by Kubernetes: `system-cluster-critical` or `system-node-critical`
|
|
* An empty set (`""`) to assign the default priority
|
|
* A pre-existing and custom defined priority class
|
|
--
|
|
|
|
[NOTE]
|
|
====
|
|
Previously, the only pod scheduling parameter that could be overriden was `priorityClassName`. This was done by adding the `operatorframework.io/priorityclass` annotation to the `CatalogSource` object. For example:
|
|
|
|
[source,yaml,subs="attributes+"]
|
|
----
|
|
apiVersion: operators.coreos.com/v1alpha1
|
|
kind: CatalogSource
|
|
metadata:
|
|
name: example-catalog
|
|
namespace: {global_ns}
|
|
annotations:
|
|
operatorframework.io/priorityclass: system-cluster-critical
|
|
----
|
|
|
|
If a `CatalogSource` object defines both the annotation and `spec.grpcPodConfig.priorityClassName`, the annotation takes precedence over the configuration parameter.
