## Synopsis

- A named resource to which messages are sent by publishers.

## 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
--- | --- | ---
auth_kind string / required | Choices: application machineaccount serviceaccount | The type of credential used.
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.
kms_key_name string added in 2.9 |  | The resource name of the Cloud KMS CryptoKey to be used to protect access to messages published on this topic. Your project's PubSub service account (`service-{{PROJECT_NUMBER}}@gcp-sa-pubsub.iam.gserviceaccount.com`) must have `roles/cloudkms.cryptoKeyEncrypterDecrypter` to use this feature. The expected format is `projects/*/locations/*/keyRings/*/cryptoKeys/*` .
labels dictionary added in 2.8 |  | A set of key/value label pairs to assign to this Topic.
message_storage_policy dictionary added in 2.9 |  | Policy constraining the set of Google Cloud Platform regions where messages published to the topic may be stored. If not present, then no constraints are in effect.
| allowed_persistence_regions list / required |  | A list of IDs of GCP regions where messages that are published to the topic may be persisted in storage. Messages published by publishers running in non-allowed GCP regions (or running outside of GCP altogether) will be routed for storage in one of the allowed regions. An empty list means that no regions are allowed, and is not a valid configuration.
name string / required |  | Name of the topic.
project string |  | The Google Cloud Platform project to use.
scopes list |  | 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.
state string | Choices: present ← absent | Whether the given object should exist in GCP
