Go-sqsd is a clone of the sqsd found on Worker applications in AWS's Elastic Beanstalk PaaS. Given a queue URL and an HTTP endpoint URL, it polls the queue for messages and POSTs them to the endpoint. If the endpoint responds with a 200 response, the messasge is deleted.
To build the cli:
go install github.com/slank/go-sqsd/cli/sqsd
usage: sqsd [options] queue_url dest_url
-http.content_type="application/json": Value of the Content-Type HTTP header
-sqs.messages_per_request=10: Maximum number of messages to receive per request
-sqs.poll_wait_seconds=20: Long poll time in seconds
-sqs.sleep_duration=10s: After an empty receive, wait this long before next poll
AWS credentials are passed via the standard methods (environment variables, user credential files, instance profiles, etc). The AWS CLI docs have a concise description of the various sources. sqsd offers no command-line options for passing AWS credentials.
You may need to set the AWS_REGION environment variable to the region where the SQS queue is defined.
