Overview

This package contains a collection of Amazon Web Service related scripts e.g.

• jlds3upload : automated file upload to S3
• jldrxsqs : receive from an SQS queue to JSON/string stdout
• jldtxsqs : transmit on SQS JSON/string from stdin
• jldleader: distributed leader election protocol manager

The philosophy behind these scripts is:

• simplicity : each script only does 1 thing
• reporting : status & error reporting through stderr and (optionally) JSON stdout
• data driven : object in from src ==> object out to dst
• data flow : piping through stdin / stdout

Scripts can easily be "composed" through standard Linux piping :

jldrxsqs @config1.txt | some_other_command | jldtxsqs @config2.txt

The data format used is JSON.

Configuration

Can be performed through options on the command line or using a file (use a leading @).
