@ -136,6 +136,11 @@ The following arguments are supported:
* `metadata` - (Optional) Metadata key/value pairs to make available from
within instances created from this template.
* `metadata_startup_script` - (Optional) An alternative to using the
startup-script metadata key, mostly to match the compute_instance resource.
This replaces the startup-script metadata key on the created instance and
thus the two mechanisms are not allowed to be used simultaneously.
* `network_interface` - (Required) Networks to attach to instances created from
this template. This can be specified multiple times for multiple networks.
Structure is documented below.
