使用Boto启动已停止的EC2实例

Question

I am writing a python script that starts a specific instance that is currently stopped, and I am kind of stumped on how I'd do that. As far as I can understand from the Boto EC2 introduction on launching instances this creates a completely new instance?

conn.run_instances(
    '<ami-image-id>',
    key_name='myKey',
    instance_type='c1.xlarge',
    security_groups=['your-security-group-here'])

Code examples would be very welcome!

Answer 1

I had completely missed this command in the API

For future reference, this is how to start a stopped instance:

instance = conn.get_all_instances(instance_ids=['instance_id'])
print instance[0].instances[0].start()

Answer 2

You can now start multiple instances in one start_instances call, eg:

conn.start_instances(instance_ids=['instance_id_1', 'instance_id_2',])
