gcp_compute_instance_template – Creates a GCP InstanceTemplate

New in version 2.6.

Synopsis

  • Defines an Instance Template resource that provides configuration settings for your virtual machine instances. Instance templates are not tied to the lifetime of an instance and can be used and reused as to deploy virtual machines. You can also use different templates to create different virtual machine configurations. Instance templates are required when you create a managed instance group.
  • Tip: Disks should be set to autoDelete=true so that leftover disks are not left behind on machine deletion.

Requirements

The below requirements are needed on the host that executes this module.

  • python >= 2.6
  • requests >= 2.18.4
  • google-auth >= 1.3.0

boolean
    Choices:
  • no
  • yes
Enables instances created based on this template to send packets with source IP addresses other than their own and receive packets with destination IP addresses other than their own.

description
-
An optional text description for the instances that are created from this instance template.
disks
-
An array of disks that are associated with the instances that are created from this template.
auto_delete
boolean
    Choices:
  • no
  • yes
Specifies whether the disk will be auto-deleted when the instance is deleted (but not when the disk is detached from the instance).
Tip: Disks should be set to autoDelete=true so that leftover disks are not left behind on machine deletion.
boot
boolean
    Choices:
  • no
  • yes
Indicates that this is a boot disk. The virtual machine will use the first partition of the disk for its root filesystem.
device_name
-
Specifies a unique device name of your choice that is reflected into the /dev/disk/by-id/google-* tree of a Linux operating system running within the instance. This name can be used to reference the device for mounting, resizing, and so on, from within the instance.
disk_encryption_key
-
Encrypts or decrypts a disk using a customer-supplied encryption key.
raw_key

source_image_encryption_key
-
The customer-supplied encryption key of the source image. Required if the source image is protected by a customer-supplied encryption key.
Instance templates do not store customer-supplied encryption keys, so you cannot create disks for instances in a managed instance group if the source images are encrypted with your own keys.
