module: gcp_pubsub_subscription
description:
- A named resource representing the stream of messages from a single, specific topic,
to be delivered to the subscribing application.
short_description: Creates a GCP Subscription
version_added: 2.6
author: Google Inc. (@googlecloudplatform)
requirements:
- python >= 2.6
- requests >= 2.18.4
- google-auth >= 1.3.0
options:
state:
description:
- Whether the given object should exist in GCP
choices:
- present
- absent
default: present
name:
description:
- Name of the subscription.
required: true
topic:
description:
- A reference to a Topic resource.
- 'This field represents a link to a Topic resource in GCP. It can be specified
in two ways. First, you can place in the name of the resource here as a string
Alternatively, you can add `register: name-of-resource` to a gcp_pubsub_topic
task and then set this topic field to "{{ name-of-resource }}"'
required: true
labels:
description:
- A set of key/value label pairs to assign to this Subscription.
required: false
version_added: 2.8
push_config:
description:
- If push delivery is used with this subscription, this field is used to configure
it. An empty pushConfig signifies that the subscriber will pull and ack messages
using API methods.
required: false
suboptions:
push_endpoint:
description:
- A URL locating the endpoint to which messages should be pushed.
- For example, a Webhook endpoint might use "U(https://example.com/push".)
required: true
attributes:
description:
- Endpoint configuration attributes.
- Every endpoint has a set of API supported attributes that can be used to
control different aspects of the message delivery.
- The currently supported attribute is x-goog-version, which you can use to
change the format of the pushed message. This attribute indicates the version
of the data expected by the endpoint. This controls the shape of the pushed
message (i.e., its fields and metadata). The endpoint version is based on
the version of the Pub/Sub API.
- If not present during the subscriptions.create call, it will default to
the version of the API used to make such call. If not present during a subscriptions.modifyPushConfig
call, its value will not be changed. subscriptions.get calls will always
return a valid version, even if the subscription was created without this
attribute.
- 'The possible values for this attribute are: - v1beta1: uses the push format
defined in the v1beta1 Pub/Sub API.'
- "- v1 or v1beta2: uses the push format defined in the v1 Pub/Sub API."
required: false
ack_deadline_seconds:
description:
- 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.
required: false
message_retention_duration:
description:
- How long to retain unacknowledged messages in the subscription's backlog, from
the moment a message is published. If retainAckedMessages is true, then this
also configures the retention of acknowledged messages, and thus configures
how far back in time a subscriptions.seek can be done. Defaults to 7 days. Cannot
be more than 7 days (`"604800s"`) or less than 10 minutes (`"600s"`).
- 'A duration in seconds with up to nine fractional digits, terminated by ''s''.
Example: `"600.5s"`.'
required: false
default: 604800s
version_added: 2.8
retain_acked_messages:
description:
- Indicates whether to retain acknowledged messages. If `true`, then messages
are not expunged from the subscription's backlog, even if they are acknowledged,
until they fall out of the messageRetentionDuration window.
required: false
type: bool
version_added: 2.8
