Using boto to fire up three Resin AMI instances.

ami-bb16ddd2 is an AMI which has Resin 4.24 on it.

from boto.ec2.connection import EC2Connection
import time

conn = EC2Connection('AWS_ACCESS_KEY', 'AWS_SECRET_KEY')

resin_image = conn.get_all_images(image_ids=["ami-bb16ddd2"])[0]
reservation = resin_image.run( min_count=3, max_count=3,
                               user_data="blah blah blah", 
                               instance_type='t1.micro',
                               key_name="resin2")

instances = reservation.instances
time.sleep(20)

count = 0
done = 0
while True:
    count += 1
    if count > 10: break
    print "Checking servers..."
    for instance in instances:
        instance.update()
        print "Server status %s " % instance.state
        if instance.state==u'running': done+=1
        
    if done >= 3: break
    time.sleep(20)

print ("All instances are running")

TODO read ~/.eucarc file for variables for AWS_ACCESS_KEY, AWS_SECRET_KEY TODO Allow passing of ami-bb16ddd2 as command line. TODO read USER_DATA from file passed as command line arg TODO pass number of servers as command line arg
