iboto 0.20.2

Amazon EC2 shell for managing multiple accounts and regions easily

Introduction

iboto offers an interactive shell with the basic set of ec2 commands from the Amazon command line tools, on steroids!

It adds:

• multiple account support

• multiple region support

• powerful filtering

• tab-completion on arguments:

  • amis

  • instance ids

  • tags

  • zones

  • instance types, etc.

  Saving much fiddly copy-pasting of ids around.

• much snappier

  Without having to load all of Java up first before running a command you’ll see it’s much snappier controlling instances compared to the Amazon tools (as great as they are!).

• extra functionality:

  • ec2ssh - waits for the instance to be running and SSH to be available before connecting; all without having to find and copy the public dns name, guess when it’s booted fully or even open a new terminal for SSH.

  • ec2watch - closely monitor what is happening to your instances whilst you’re waiting.

• all the nice features of ipython

  History recall, python integration, session recording, configurability, etc.

It’s probably best illustrated with a demo session:

~ % iboto
iboto ready

Commands available:
%ec2din  (aka ls)
%limit   (aka .)
%pop     (aka ..)
%ec2ssh
%ec2run
%ec2start
%ec2stop
%ec2kill
%ec2watch
%account
%region

Installation

Install with your favourite package manager:

$ pip install iboto

You can then run iboto from your path:

$ iboto

The default is to start the shell with every account/region visible. You can limit to a specific account/region from the command line:

$ iboto demo1 eu-west-1

Configuration

The first time iboto is run you’ll be taken through a wizard which will configure the credentials for your account(s).

Help

The best documentation is the command documentation accessed by entering ‘%command?’ at the shell prompt, e.g.:

'%ec2start?'

'%limit?'

Future plans

• Add the full set of ec2 tools

• Add further AWS apis.

• Parallel ec2ssh execution for more than one host.
