#AWS TAG SNS TOPIC SQS QUEUE HOW TO#

If I can find a sensible way with the cli client it will most likely be available in the ruby sdk. If it helps, this will be using the Ruby SDK - but I think that the clients across the languages are pretty much all the same. Checking whether the queue exists and creating it if not is easy, subscribing a queue to a particular SNS topic on boot is also easy - but I can't seem to find a sensible way of checking whether a particular queue is already subscribed to a topic!

Something I'm struggling with now is how to ensure that an SNS subscription for the queue exists. For instance, on service boot, it checks whether its queues exist already in AWS and creates them if they don't. All Rights Reserved.I've found it's a useful strategy to create relevant queues whenever a queue worker service boots.

This flag is ignored if any of the following are defined: topicProps.masterKey, queueProps.encryptionMasterKey, encryptionKey or encryptionKeyProps.Īn optional, imported encryption key to encrypt the SQS Queue and SNS Topic with. If no key is provided, this flag determines whether the queue is encrypted with a new CMK or an AWS managed key.
