Demo

Remove this once we have the SQS controller

aws sqs receive-message --queue-url $(aws sqs get-queue-url --queue-name demo | jq -r ".QueueUrl")

aws sqs send-message --queue-url $(aws sqs get-queue-url --queue-name demo | jq -r ".QueueUrl") --message-body "$(echo $(k get events -ojson | jq ".items[0]"))"

aws sqs delete-message --queue-url demo --receipt-handle $(aws sqs receive-message --queue-url $(aws sqs get-queue-url --queue-name demo | jq -r ".QueueUrl") | jq -r ".Messages[].ReceiptHandle")
