ip_forward
bool

(added in 1.9)
    Choices:
  • no ←
  • yes
set to yes if the instance can forward ip packets (useful for gateways)
machine_type Default:
n1-standard-1
machine type to use for the instance, use 'n1-standard-1' by default
metadata
a hash/dictionary of custom data for the instance; '{"key":"value", ...}'
name
either a name of a single instance or when used with 'num_instances', the base name of a cluster of nodes

aliases: base_name

(added in 2.3)
can be used with 'name', specifies the number of nodes to provision using 'name' as a base name

preemptible
bool

(added in 2.1)
    Choices:
  • no ←
  • yes

name of the subnetwork in which the instance should be created
tags
a comma-separated list of tags to associate with the instance
zone
required
Default:
us-central1-a
the GCE zone to use. The list of available zones is at https://cloud.google.com/compute/docs/regions-zones/regions-zones#available.

Notes

Note

  • Either instance_names or name is required.
  • JSON credentials strongly preferred.
