If there's 20 // no conflict, the pod's tolerations are merged with its namespace's 21 // toleration. Resulting pod's tolerations are verified against its 22 // namespace's whitelist of tolerations. If the verification is 23 // successful, the pod is admitted otherwise rejected. If a namespace 24 // does not have associated default or whitelist of tolerations, then 25 // cluster level default or whitelist of tolerations are used instead 26 // if specified. Tolerations to a namespace are assigned via 27 // scheduler.alpha.kubernetes.io/defaultTolerations and 28 // scheduler.alpha.kubernetes.io/tolerationsWhitelist annotations 29 // keys. 30 package podtolerationrestriction // import "k8s.io/kubernetes/plugin/pkg/admission/podtolerationrestriction" 31
