Python script to output current EC2 instance information to a text file, ideally
for Conky to display on your desktop.

Expects the standard AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY environment
variables to be defined.

Requires the boto Python package:
$ pip install boto

"""
#!/usr/bin/env python
import os
import boto.ec2

AWS_ACCESS_KEY = os.environ['AWS_ACCESS_KEY_ID']
AWS_SECRET_KEY = os.environ['AWS_SECRET_ACCESS_KEY']
EC2_CONNECTION = boto.ec2.EC2Connection(AWS_ACCESS_KEY, AWS_SECRET_KEY)

output = open(os.environ['HOME']+ '/.conkec2', 'w')

for reservation in EC2_CONNECTION.get_all_instances():
    for instance in reservation.instances:
        output.write(instance.id + ": ")
        output.write(instance.state + "\n")
        output.write(instance.instance_type + "\n")
        output.write(instance.launch_time + "\n")
        output.write(instance.dns_name + "\n")
        output.write("\n")
