google.cloud.gcp_tpu_node_info – Gather info for GCP Node

Note

This plugin is part of the google.cloud collection (version 1.0.2).

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.

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

Synopsis

  • Gather info for GCP Node

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

Comments

auth_kind

string / required

The type of credential used.

Choices:

  • application

  • machineaccount

  • serviceaccount

env_type

string

Specifies which Ansible environment you’re running this module within.

This should not be set unless you know what you’re doing.

This only alters the User Agent string for any API requests.

project

string

The Google Cloud Platform project to use.

scopes

list / elements=string

Array of scopes to be used

service_account_contents

jsonarg

The contents of a Service Account JSON file, either in a dictionary or as a JSON string that represents it.

service_account_email

string

An optional service account email address if machineaccount is selected and the user does not wish to use the default email.

service_account_file

path

The path of a Service Account JSON file if serviceaccount is selected as type.

zone

string

The GCP location for the TPU. If it is not provided, the provider zone is used.

Notes

Note

  • for authentication, you can set service_account_file using the gcp_service_account_file env variable.

  • for authentication, you can set service_account_contents using the GCP_SERVICE_ACCOUNT_CONTENTS env variable.

  • For authentication, you can set service_account_email using the GCP_SERVICE_ACCOUNT_EMAIL env variable.

  • For authentication, you can set auth_kind using the GCP_AUTH_KIND env variable.

  • For authentication, you can set scopes using the GCP_SCOPES env variable.

  • Environment variables values will only be used if the playbook values are not set.

  • The service_account_email and service_account_file options are mutually exclusive.

Examples

- name: get info on a node
  gcp_tpu_node_info:
    zone: us-central1-b
    project: test_project
    auth_kind: serviceaccount
    service_account_file: "/tmp/auth.pem"

Return Values

Common return values are documented here, the following are the fields unique to this module:

Key

Description

resources

complex

List of resources

Returned: always

acceleratorType

string

The type of hardware accelerators associated with this node.

Returned: success

cidrBlock

string

The CIDR block that the TPU node will use when selecting an IP address. This CIDR block must be a /29 block; the Compute Engine networks API forbids a smaller block, and using a larger block would be wasteful (a node can only consume one IP address).

Errors will occur if the CIDR block has already been used for a currently existing TPU node, the CIDR block conflicts with any subnetworks in the user’s provided network, or the provided network is peered with another network that is using that CIDR block.

Returned: success

description

string

The user-supplied description of the TPU. Maximum of 512 characters.

Returned: success

labels

dictionary

Resource labels to represent user provided metadata.

Returned: success

name

string

The immutable name of the TPU.

Returned: success

network

string

The name of a network to peer the TPU node to. It must be a preexisting Compute Engine network inside of the project on which this API has been activated. If none is provided, “default” will be used.

Returned: success

networkEndpoints

complex

The network endpoints where TPU workers can be accessed and sent work.

It is recommended that Tensorflow clients of the node first reach out to the first (index 0) entry.

Returned: success

ipAddress

string

The IP address of this network endpoint.

Returned: success

port

integer

The port of this network endpoint.

Returned: success

schedulingConfig

complex

Sets the scheduling options for this TPU instance.

Returned: success

preemptible

boolean

Defines whether the TPU instance is preemptible.

Returned: success

serviceAccount

string

The service account used to run the tensor flow services within the node. To share resources, including Google Cloud Storage data, with the Tensorflow job running in the Node, this account must have permissions to that data.

Returned: success

tensorflowVersion

string

The version of Tensorflow running in the Node.

Returned: success

useServiceNetworking

boolean

Whether the VPC peering for the node is set up through Service Networking API.

The VPC Peering should be set up before provisioning the node. If this field is set, cidr_block field should not be specified. If the network that you want to peer the TPU Node to is a Shared VPC network, the node must be created with this this field enabled.

Returned: success

zone

string

The GCP location for the TPU. If it is not provided, the provider zone is used.

Returned: success
