AWS SQS - SpringBoot - 403 禁止

Question

I'm trying to access the AWS SQS list from a SpringBoot app which is deployed on AWS/eks but I am getting a 403 Forbidden as an error.

Do I have to add something specific to the AWS SQS Access Policy in order to grant access to the client as a producer/consumer?

I am not trying to push into the queue so far, I just want to see the list of the queues.

Thanks in advance

public ResponseEntity<ListQueuesResult> readQueueList() {
    AmazonSQS sqs = AmazonSQSClientBuilder.defaultClient();
    ListQueuesResult listOfQueues = sqs.listQueues();
    log.info("List of Queues: {}", listOfQueues);
    return ResponseEntity.ok(listOfQueues);
}

That is the biggest policy for an sqs i ever saw :D Is this autogenerated by some framework :) ?

Yes, you have to explicitly allow to read from the queue.

If I'm not wrong, it is with the

    "sqs:ReceiveMessage",
    "sqs:GetQueueAttributes",
    "sqs:DeleteMessage" Actions 

You have it in 2 places, so first i would check, if the conditions for those Actions are met.

If you are in control of the policy, I would:

1. make copy of it
2. slowly remove security until you can connect
3. find out why you could not connect originally (obligatory slap yourself on the forehead :)
4. Add removed security back
