google.cloud.gcp_compute_instance module – Creates a GCP Instance

Note

This module is part of the google.cloud collection (version 1.4.1).

You might already have this collection installed if you are using the ansible package. It is not included in ansible-core. To check whether it is installed, run ansible-galaxy collection list.

To install it, use: ansible-galaxy collection install google.cloud. You need further requirements to be able to use this module, see Requirements for details.

To use it in a playbook, specify: google.cloud.gcp_compute_instance.

Note

The google.cloud collection will be removed from Ansible 12 due to violations of the Ansible inclusion requirements. The collection has unresolved sanity test failures. See the discussion thread for more information.

confidential_instance_config dictionary	Configuration for confidential computing (requires setting the machine type to any of the n2d-* types and a boot disk of type pd-ssd).
enable_confidential_compute boolean	Enables confidential computing. Choices: `false` `true`

boot boolean	Indicates that this is a boot disk. The virtual machine will use the first partition of the disk for its root filesystem. Choices: `false` `true`
device_name string	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.

raw_key string	Specifies a 256-bit customer-supplied encryption key, encoded in RFC 4648 base64 to either encrypt or decrypt this resource.
rsa_encrypted_key string	Specifies an RFC 4648 base64 encoded, RSA-wrapped 2048-bit customer-supplied encryption key to either encrypt or decrypt this resource.
index integer	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 dictionary	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 string	Specifies the disk name. If not specified, the default is to use the name of the instance.

source_image_encryption_key dictionary	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.
