| APIVersion defines the versioned schema of this representation of an object. Servers should convert recognized schemas to the latest internal value, and may reject unrecognized values. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#resources |
|
| Kind is a string value representing the REST resource this object represents. Servers may infer this from the endpoint the client submits requests to. Cannot be updated. In CamelCase. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds |

| defaultNodeSelector helps set the cluster-wide default node selector to restrict pod placement to specific nodes. This is applied to the pods created in all namespaces and creates an intersection with any existing nodeSelectors already set on a pod, additionally constraining that pod’s selector. For example, defaultNodeSelector: “type=user-node,region=east” would set nodeSelector field in pod spec to “type=user-node,region=east” to all pods created in all namespaces. Namespaces having project-wide node selectors won’t be impacted even if this field is set. This adds an annotation section to the namespace. For example, if a new namespace is created with node-selector=’type=user-node,region=east’, the annotation openshift.io/node-selector: type=user-node,region=east gets added to the project. When the openshift.io/node-selector annotation is set on the project the value is used in preference to the value we are setting for defaultNodeSelector field. For instance, openshift.io/node-selector: “type=user-node,region=west” means that the default of “type=user-node,region=east” set in defaultNodeSelector would not be applied. |
|
| MastersSchedulable allows masters nodes to be schedulable. When this flag is turned on, all the master nodes in the cluster will be made schedulable, so that workload pods can run on them. The default value for this field is false, meaning none of the master nodes are schedulable. Important Note: Once the workload pods start running on the master nodes, extreme care must be taken to ensure that cluster-critical control plane components are not impacted. Please turn on this field after doing due diligence. |
|
| DEPRECATED: the scheduler Policy API has been deprecated and will be removed in a future release. policy is a reference to a ConfigMap containing scheduler policy which has user specified predicates and priorities. If this ConfigMap is not available scheduler will default to use DefaultAlgorithmProvider. The namespace for this configmap is openshift-config. |
|
| profile sets which scheduling profile should be set in order to configure scheduling decisions for new pods. Valid values are “LowNodeUtilization”, “HighNodeUtilization”, “NoScoring” Defaults to “LowNodeUtilization” |

| When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed |
|
| fieldValidation instructs the server on how to handle objects in the request (POST/PUT/PATCH) containing unknown or duplicate fields. Valid values are: - Ignore: This will ignore any unknown fields that are silently dropped from the object, and will ignore all but the last duplicate field that the decoder encounters. This is the default behavior prior to v1.23. - Warn: This will send a warning via the standard warning response header for each unknown field that is dropped from the object, and for each duplicate field that is encountered. The request will still succeed if there are no other errors, and will only persist the last of any duplicate fields. This is the default in v1.23+ - Strict: This will fail the request with a BadRequest error if any unknown fields would be dropped from the object, or if any duplicate fields are present. The error returned from the server will contain all unknown and duplicate fields encountered. |
