Represents a query that applied over pods, returns the number of pods which should match the "replica" count. This is the query used by the replication controller to figure out whether it has to spin up or shut down pods. The labels specified in the "spec.selector" map must match the labels applied to the pods created by this deployment configuration, which are the "[[#spec.template.metadata.labels|spec.template.metadata.labels]]".
