gcp_pubsub_subscription – Creates a GCP Subscription

New in version 2.6.

Synopsis

  • A named resource representing the stream of messages from a single, specific topic, to be delivered to the subscribing application.

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
ack_deadline_seconds
-
This value is the maximum time after a subscriber receives a message before the subscriber should acknowledge the message. After message delivery but before the ack deadline expires and before the message is acknowledged, it is an outstanding message and will not be delivered again during that time (on a best-effort basis).
For pull subscriptions, this value is used as the initial value for the ack deadline. To override this value for a given message, call subscriptions.modifyAckDeadline with the corresponding ackId if using pull. The minimum custom deadline you can specify is 10 seconds. The maximum custom deadline you can specify is 600 seconds (10 minutes).
If this parameter is 0, a default value of 10 seconds is used.
For push delivery, this value is also used to set the request timeout for the call to the push endpoint.
If the subscriber never acknowledges the message, the Pub/Sub system will eventually redeliver the message.
auth_kind

    Choices:
  • machineaccount
  • serviceaccount
  • application

push_config
-

push_endpoint
-
A URL locating the endpoint to which messages should be pushed.
For example, a Webhook endpoint might use "https://example.com/push".
