// defaultNodeSelector helps set the cluster-wide default node selector to

// 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.

// 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.
