When using Container Engine for Kubernetes to define a node pool's placement configuration, you can now specify preemptible capacity as the capacity type of compute instances hosting worker nodes in the node pool.

Preemptible capacity enables you to save money by using preemptible instances to run workloads that only need to run for brief periods or that can be interrupted when the capacity is reclaimed. Preemptible instances behave the same as regular compute instances, but the capacity is reclaimed when it's needed elsewhere, and the instances are terminated.
