## Synopsis

- The `sns_topic` module allows you to create, delete, and manage subscriptions for AWS SNS topics. As of 2.6, this module can be use to subscribe and unsubscribe to topics outside of your AWS account.

## Requirements

The below requirements are needed on the host that executes this module.

- boto
- python >= 2.6

## Parameters

Parameter | Choices/Defaults | Comments
--- | --- | ---
aws_access_key string |  | AWS access key. If not set then the value of the AWS_ACCESS_KEY_ID, AWS_ACCESS_KEY or EC2_ACCESS_KEY environment variable is used. aliases: ec2_access_key, access_key
aws_secret_key string |  | AWS secret key. If not set then the value of the AWS_SECRET_ACCESS_KEY, AWS_SECRET_KEY, or EC2_SECRET_KEY environment variable is used. aliases: ec2_secret_key, secret_key
debug_botocore_endpoint_logs boolean added in 2.8 | Choices: no ← yes | Use a botocore.endpoint logger to parse the unique (rather than total) "resource:action" API calls made during a task, outputing the set to the resource_actions key in the task results. Use the aws_resource_action callback to output to total list made during a playbook. The ANSIBLE_DEBUG_BOTOCORE_LOGS environment variable may also be used.
delivery_policy - |  | Delivery policy to apply to the SNS topic
display_name - |  | Display name of the topic
ec2_url string |  | Url to use to connect to EC2 or your Eucalyptus cloud (by default the module will use EC2 endpoints). Ignored for modules where region is required. Must be specified for all other modules if region is not used. If not set then the value of the EC2_URL environment variable, if any, is used.
name - / required |  | The name or ARN of the SNS topic to manage
policy - |  | Policy to apply to the SNS topic
profile string |  | Uses a boto profile. Only works with boto >= 2.24.0.
purge_subscriptions boolean | Choices: no yes ← | Whether to purge any subscriptions not listed here. NOTE: AWS does not allow you to purge any PendingConfirmation subscriptions, so if any exist and would be purged, they are silently skipped. This means that somebody could come back later and confirm the subscription. Sorry. Blame Amazon.
region string |  | The AWS region to use. If not specified then the value of the AWS_REGION or EC2_REGION environment variable, if any, is used. See http://docs.aws.amazon.com/general/latest/gr/rande.html#ec2_region aliases: aws_region, ec2_region
security_token string |  | AWS STS security token. If not set then the value of the AWS_SECURITY_TOKEN or EC2_SECURITY_TOKEN environment variable is used. aliases: access_token
state - | Choices: absent present ← | Whether to create or destroy an SNS topic
subscriptions - | Default: [] | List of subscriptions to apply to the topic. Note that AWS requires subscriptions to be confirmed, so you will need to confirm any new subscriptions.
| endpoint - / required |  | Endpoint of subscription
| protocol - / required |  | Protocol of subscription
validate_certs boolean | Choices: no yes ← | When set to "no", SSL certificates will not be validated for boto versions >= 2.6.0.

## Notes

Note

- If parameters are not set within the module, the following environment variables can be used in decreasing order of precedence `AWS_URL` or `EC2_URL`, `AWS_ACCESS_KEY_ID` or `AWS_ACCESS_KEY` or `EC2_ACCESS_KEY`, `AWS_SECRET_ACCESS_KEY` or `AWS_SECRET_KEY` or `EC2_SECRET_KEY`, `AWS_SECURITY_TOKEN` or `EC2_SECURITY_TOKEN`, `AWS_REGION` or `EC2_REGION`
- Ansible uses the boto configuration file (typically ~/.boto) if no credentials are provided. See https://boto.readthedocs.io/en/latest/boto_config_tut.html
- `AWS_REGION` or `EC2_REGION` can be typically be used to specify the AWS region, when required, but this can also be configured in the boto config file
