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
type: str
name:
description:
- Name of the subscription.
required: true
type: str
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 a dictionary with key ''name'' and value of
your resource''s name 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
type: dict
labels:
description:
- A set of key/value label pairs to assign to this Subscription.
required: false
type: dict
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
type: dict
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
type: str
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
type: dict
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
type: int
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
type: str
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'
expiration_policy:
description:
- A policy that specifies the conditions for this subscription's expiration.
- A subscription is considered active as long as any connected subscriber is successfully
consuming messages from the subscription or is issuing operations on the subscription.
If expirationPolicy is not set, a default policy with ttl of 31 days will be
used. The minimum allowed value for expirationPolicy.ttl is 1 day.
required: false
type: dict
version_added: '2.9'
suboptions:
ttl:
description:
- Specifies the "time-to-live" duration for an associated resource. The resource
expires if it is not active for a period of ttl. The definition of "activity"
depends on the type of the associated resource. The minimum and maximum
allowed values for ttl depend on the type of the associated resource, as
well. If ttl is not set, the associated resource never expires.
- A duration in seconds with up to nine fractional digits, terminated by 's'.
- Example - "3.5s".
required: false
type: str
project:
description:
- The Google Cloud Platform project to use.
type: str
auth_kind:
description:
- The type of credential used.
type: str
required: true
choices:
- application
- machineaccount
- serviceaccount
service_account_contents:
description:
- The contents of a Service Account JSON file, either in a dictionary or as a
JSON string that represents it.
type: jsonarg
service_account_file:
description:
- The path of a Service Account JSON file if serviceaccount is selected as type.
type: path
service_account_email:
description:
- An optional service account email address if machineaccount is selected and
the user does not wish to use the default email.
type: str
scopes:
description:
- Array of scopes to be used
type: list
env_type:
description:
- 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.
type: str
notes:
- 'API Reference: U(https://cloud.google.com/pubsub/docs/reference/rest/v1/projects.subscriptions)'
- 'Managing Subscriptions: U(https://cloud.google.com/pubsub/docs/admin#managing_subscriptions)'
- for authentication, you can set service_account_file using the c(gcp_service_account_file)
env variable.
- for authentication, you can set service_account_contents using the c(GCP_SERVICE_ACCOUNT_CONTENTS)
env variable.
- For authentication, you can set service_account_email using the C(GCP_SERVICE_ACCOUNT_EMAIL)
env variable.
- For authentication, you can set auth_kind using the C(GCP_AUTH_KIND) env variable.
- For authentication, you can set scopes using the C(GCP_SCOPES) env variable.
- Environment variables values will only be used if the playbook values are not set.
- The I(service_account_email) and I(service_account_file) options are mutually exclusive.
