// Package podtolerationrestriction is a plugin that first verifies
|
|
// any conflict between a pod's tolerations and its namespace's
|
|
// tolerations, and rejects the pod if there's a conflict. If there's
|
|
// no conflict, the pod's tolerations are merged with its namespace's
|
|
// toleration. Resulting pod's tolerations are verified against its
|
|
// namespace's whitelist of tolerations. If the verification is
|
|
// successful, the pod is admitted otherwise rejected. If a namespace
|
|
// does not have associated default or whitelist of tolerations, then
|
|
// cluster level default or whitelist of tolerations are used instead
|
|
// if specified. Tolerations to a namespace are assigned via
|
|
// scheduler.alpha.kubernetes.io/defaultTolerations and
|
|
// scheduler.alpha.kubernetes.io/tolerationsWhitelist annotations
|
|
// keys.
