    "Statement": [
        {
            "Action": [
                "sqs:ListQueues",
                "sqs:GetQueueAttributes"

            "Effect": "Allow",
            "Resource": "*"
        }
    ]
}

We recommend using EC2/ECS Task roles so that you don't need to send credentials into the container, however if you can't use those or want to send in specific Access Keys and Secret keys, please see the AWS Documentation as to how you do that.
