// An EphemeralContainer is a temporary container that you may add to an existing Pod for
// user-initiated activities such as debugging. Ephemeral containers have no resource or
// scheduling guarantees, and they will not be restarted when they exit or when a Pod is
// removed or restarted. The kubelet may evict a Pod if an ephemeral container causes the
// Pod to exceed its resource allocation.
