AWS tools

Note

This is very beta, use at your own risk. That said, I am using it production.

Until my filter patch gets pulled, you’ll need to use this version of amazon-ec2:

https://github.com/stw/amazon-ec2/tree/add_filters_to_snapshots

Description

A simple gem to provide aws command line tools, currently only snapshots. snapshots allows you to create snapshots from volumes on aws and deletes snapshots greater than the keep parameter.

Usage

snapshots -v volume-id -k 2 -d "Some Description" -q

Creates a snapshot of volume-id, and deletes all snapshots except for the current and the last most recent.

If you’re using rvm and want to run it from cron you have to do something like this:

0 0 * * * /bin/bash -l -c 'snapshots -v volume-id -d "Some Description"'

This ensures rvm is loaded before running the script.

Installation

Ensure you set your amazon keys.

export EC2_PRIVATE_KEY=/path/to/private_key.pem 
export EC2_CERT=/path/to/cert.pem

gem install awstools

snapshot -v volume-id -k 2 -d "Some Description"

snapshot --help for params

options:

Usage:
     snapshots [options]

where [options] are:
     --volume, -v <s>:   Volume to snapshot
       --keep, -k <i>:   Snapshots to keep (default: 2)
--description, -d <s>:   Snapshot description
          --quiet, -q:   Don't print anything
       --simulate, -s:   Simulate, nothing created/deleted
           --help, -h:   Show this message

Reason

I looked for a simple tool to do this and didn’t find anything I liked so I put this together.
