Optional. The Customer Managed Encryption Key (CMEK)
used to encrypt the boot disk attached to each node in the node pool.
Specify the key using the following format:
<code>projects/<var>KEY_PROJECT_ID</var>/locations/<var>LOCATION</var>/keyRings/<var>RING_NAME</var>/cryptoKeys/<var>KEY_NAME</var></code>.
Optional. The number of local SSD disks to attach to the node, which is
limited by the maximum number of disks allowable per zone (see Adding
Local SSDs).
Optional. Minimum CPU
platform
to be used by this instance. The instance may be scheduled on the
specified or a newer CPU platform. Specify the friendly names of CPU
platforms, such as "Intel Haswell"` or Intel Sandy Bridge".
Optional. Whether the nodes are created as legacy preemptible VM
instances.

[Spot][google.cloud.dataproc.v1.GkeNodePoolConfig.GkeNodeConfig.spot]
VMs, preemptible VM instances without a maximum lifetime. Legacy and Spot
preemptible nodes cannot be used in a node pool with the CONTROLLERrole
or in the DEFAULT node pool if the CONTROLLER role is not assigned (the
DEFAULT node pool will assume the CONTROLLER role).
Optional. Whether the nodes are created as Spot VM instances.
Spot VMs are the latest update to legacy
[preemptible
VMs][google.cloud.dataproc.v1.GkeNodePoolConfig.GkeNodeConfig.preemptible].
Spot VMs do not have a maximum lifetime. Legacy and Spot preemptible
nodes cannot be used in a node pool with the CONTROLLERrole
or in the DEFAULT node pool if the CONTROLLER role is not assigned (the
DEFAULT node pool will assume the CONTROLLER role).
