# aws\_sns\_topic\_subscription
|
||||
|
||||
Provides a resource for subscribing to SNS topics. Requires that an SNS topic exist for the subscription to attach to.
|
||||
This resource allows you to automatically place messages sent to SNS topics in SQS queues, send them as HTTP(S) POST requests
|
||||
to a given endpoint, send SMS messages, or notify devices / applications. The most likely use case for Terraform users will
|
||||
probably be SQS queues.
|
||||
|
||||
## Example Usage
|
||||
|
||||
You can directly supply a topic ARN by hand in the `topic_arn` property:
|
||||
|
||||
```
|
||||
resource "aws_sns_topic_subscription" "user_updates_sqs_target" {
|
||||
topic_arn = "arn:aws:sns:us-west-2:432981146916:user-updates-topic"
|
||||
topic_arn = "${aws_sns_topic.user_updates.id}"
|
||||
protocol = "sqs"
|
||||
endpoint = "arn:aws:sqs:us-west-2:432981146916:terraform-queue-too"
|
||||
}
|
||||
```
|
||||
|
||||
Alternatively you can use the identifier of a previously created SNS topic:
|
||||
|
||||
```
|
||||
resource "aws_sns_topic" "user_updates" {
|
||||
name = "user-updates-topic"
|
||||
}
|
||||
|
||||
resource "aws_sns_topic_subscription" "user_updates_sqs_target" {
|
||||
topic_arn = "${aws_sns_topic.user_updates.id}"
|
||||
protocol = "sqs"
|
||||
endpoint = "arn:aws:sqs:us-west-2:432981146916:terraform-queue-too"
|
||||
}
|
||||
```
|
||||
|
||||
|
||||
Currently there is no SQS support, so you need to know the queue ARN ahead of time, however it would make sense to be
|
||||
able to populate the endpoint from an SQS resource in your JSON file.
|
||||
|
||||
## Argument Reference
|
||||
|
||||
The following arguments are supported:
|
||||
|
||||
* `topic_arn` - (Required) The ARN of the SNS topic to subscribe to
|
||||
* `protocol` - (Required) The protocol to use. The possible values for this are: `sqs`, `http`, `https`, `sms`, or `application`. (`email` is an option but unsupported, see below)
|
||||
* `endpoint` - (Required) The endpoint to send data to, the contents will vary with the protocol. (see below for more information)
|
||||
|
||||
### Protocols supported
|
||||
|
||||
Supported SNS protocols include:
|
||||
|
||||
* `http` -- delivery of JSON-encoded message via HTTP POST
|
||||
* `https` -- delivery of JSON-encoded message via HTTPS POST
|
||||
* `sms` -- delivery of message via SMS
|
||||
* `sqs` -- delivery of JSON-encoded message to an Amazon SQS queue
|
||||
* `application` -- delivery of JSON-encoded message to an EndpointArn for a mobile app and device
|
||||
|
||||
Unsupported protocols include the following:
|
||||
|
||||
* `email` -- delivery of message via SMTP
|
||||
* `email-json` -- delivery of JSON-encoded message via SMTP
|
||||
|
||||
These are unsupported because the email address needs to be authorized and does not generate an ARN until the target email address has been validated. This breaks
|
||||
the Terraform model and as a result are not currently supported.
|
||||
|
||||
### Specifying endpoints
|
||||
|
||||
Endpoints have different format requirements according to the protocol that is chosen.
|
||||
|
||||
* HTTP/HTTPS endpoints will require a URL to POST data to
|
||||
* SMS endpoints are mobile numbers that are capable of receiving an SMS
|
||||
* SQS endpoints come in the form of the SQS queue's ARN (not the URL of the queue) e.g: `arn:aws:sqs:us-west-2:432981146916:terraform-queue-too`
|
||||
* Application endpoints are also the endpoint ARN for the mobile app and device.
|
||||
|
||||
|
||||
## Attributes Reference
|
||||
|
||||
The following attributes are exported:
|
||||
|
||||
* `id` - The ARN of the subscription
|
||||
* `topic_arn` - The ARN of the topic the subscription belongs to
|
||||
* `protocol` - The protocol being used
|
||||
* `endpoint` - The full endpoint to send data to (SQS ARN, HTTP(S) URL, Application ARN, SMS number, etc.)
