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

Parameters

Parameter Choices/Defaults Comments

- / required

Name of the resource. The name is 1-63 characters long and complies with RFC1035.

project

string

The Google Cloud Platform project to use.

properties

-

The instance properties for this instance template.

can_ip_forward

boolean

  • 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. If these instances will be used as an IP gateway or it will be set as the next-hop in a Route resource, specify true. If unsure, leave this set to false.

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

  • 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

  • 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

-

Specifies a 256-bit customer-supplied encryption key, encoded in RFC 4648 base64 to either encrypt or decrypt this resource.

rsa_encrypted_key

-

Specifies an RFC 4648 base64 encoded, RSA-wrapped 2048-bit customer-supplied encryption key to either encrypt or decrypt this resource.

index

-

Assigns a zero-based index to this disk, where 0 is reserved for the boot disk. For example, if you have many disks attached to an instance, each disk would have a unique index number. If not specified, the server will choose an appropriate value.

initialize_params

-

Specifies the parameters for a new disk that will be created alongside the new instance. Use initialization parameters to create boot disks or local SSDs attached to the new instance.

disk_name

-

Specifies the disk name. If not specified, the default is to use the name of the instance.

disk_size_gb

-

Specifies the size of the disk in base-2 GB.

disk_type

-

Reference to a disk type.

Specifies the disk type to use to create the instance.

If not specified, the default is pd-standard.

source_image

-

The source image to create this disk. When creating a new instance, one of initializeParams.sourceImage or disks.source is required. To create a disk with one of the public operating system images, specify the image by its family name.

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.

raw_key

-

Specifies a 256-bit customer-supplied encryption key, encoded in RFC 4648 base64 to either encrypt or decrypt this resource.

interface

-

  • SCSI
  • NVME

Specifies the disk interface to use for attaching this disk, which is either SCSI or NVME. The default is SCSI.

Persistent disks must always use SCSI and the request will fail if you attempt to attach a persistent disk in any other format than SCSI.

mode

  • READ_WRITE
  • READ_ONLY

The mode in which to attach this disk, either READ_WRITE or READ_ONLY. If not specified, the default is to attach the disk in READ_WRITE mode.

source

-

Reference to a disk. When creating a new instance, one of initializeParams.sourceImage or disks.source is required.

If desired, you can also attach existing non-root persistent disks using this property. This field is only applicable for persistent disks.

Note that for InstanceTemplate, specify the disk name, not the URL for the disk.

This field represents a link to a Disk resource in GCP. It can be specified in two ways. First, you can place a dictionary with key 'name' and value of your resource's name Alternatively, you can add `register: name-of-resource` to a gcp_compute_disk task and then set this source field to "Template:Name-of-resource"

This field represents a link to a Address resource in GCP. It can be specified in two ways. First, you can place a dictionary with key 'address' and value of your resource's address Alternatively, you can add `register: name-of-resource` to a gcp_compute_address task and then set this nat_ip field to "Template:Name-of-resource"

type

- / required

  • ONE_TO_ONE_NAT

Specifies the title of an existing network. When creating an instance, if neither the network nor the subnetwork is specified, the default network global/networks/default is used; if the network is not specified but the subnetwork is specified, the network is inferred.

This field represents a link to a Network resource in GCP. It can be specified in two ways. First, you can place a dictionary with key 'selfLink' and value of your resource's selfLink Alternatively, you can add `register: name-of-resource` to a gcp_compute_network task and then set this network field to "Template:Name-of-resource"

If the network resource is in legacy mode, do not provide this property. If the network is in auto subnet mode, providing the subnetwork is optional. If the network is in custom subnet mode, then this field should be specified.

This field represents a link to a Subnetwork resource in GCP. It can be specified in two ways. First, you can place a dictionary with key 'selfLink' and value of your resource's selfLink Alternatively, you can add `register: name-of-resource` to a gcp_compute_subnetwork task and then set this subnetwork field to "Template:Name-of-resource"
