Adding SQS redrive policy using AWS CLI command

Question

I am trying to set redrive policy for SQS using the AWS CLI Command below , but seeing an error related to redrive JSON. Can you please let me know how I can fix this?

redrive_policy="{\"RedrivePolicy\":{\"deadLetterTargetArn\":\"$dlq_arn\",\"maxReceiveCount\":\"15\"}}"

AWS CLI COMMAND

aws sqs set-queue-attributes --queue-url https://queue.amazonaws.com/12345678/test-queue --attributes $redrive_policy --region=us-east-1

Error Message

Parameter validation failed: Invalid type for parameter Attributes.RedrivePolicy, value: OrderedDict([(u'deadLetterTargetArn', u'arn:aws:sqs:us-east-1:12345678:dlq'), (u'maxReceiveCount', u'15')]), type: , valid types:

Answer 1

Have you tried just creating the JSON in a separate file and passing it as an argument to your AWS CLI command? I find it's difficult to get all of the escaping correct when passing the JSON as a parameter. So you'd basically do it as the example shows in the AWS documentation:

https://docs.aws.amazon.com/cli/latest/reference/sqs/set-queue-attributes.html#examples

1. So first you'd create a new file called "set-queue-attributes.json" like so:

    {
      "DelaySeconds": "10",
      "MaximumMessageSize": "131072",
      "MessageRetentionPeriod": "259200",
      "ReceiveMessageWaitTimeSeconds": "20",
      "RedrivePolicy": "{\"deadLetterTargetArn\":\"arn:aws:sqs:us-east-1:80398EXAMPLE:MyDeadLetterQueue\",\"maxReceiveCount\":\"1000\"}",
      "VisibilityTimeout": "60"
    }

2. Then run the command like this:

aws sqs set-queue-attributes --queue-url https://sqs.us-east-1.amazonaws.com/80398EXAMPLE/MyNewQueue --attributes file://set-queue-attributes.json --region=us-east-1
