SYNOPSIS
|
|
launch_ami.py -a ami_id [-b script_bucket] [-s script_name]
|
|
[-m module] [-c class_name] [-r]
|
|
[-g group] [-k key_name] [-n num_instances]
|
|
[-w] [extra_data]
|
|
Where:
|
|
ami_id - the id of the AMI you wish to launch
|
|
module - The name of the Python module containing the class you
|
|
want to run when the instance is started. If you use this
|
|
option the Python module must already be stored on the
|
|
instance in a location that is on the Python path.
|
|
script_file - The name of a local Python module that you would like
|
|
to have copied to S3 and then run on the instance
|
|
when it is started. The specified module must be
|
|
import'able (i.e. in your local Python path). It
|
|
will then be copied to the specified bucket in S3
|
|
(see the -b option). Once the new instance(s)
|
|
start up the script will be copied from S3 and then
|
|
run locally on the instance.
|
|
class_name - The name of the class to be instantiated within the
|
|
module or script file specified.
|
|
script_bucket - the name of the bucket in which the script will be
|
|
stored
|
|
group - the name of the security group the instance will run in
|
|
key_name - the name of the keypair to use when launching the AMI
|
|
num_instances - how many instances of the AMI to launch (default 1)
|
|
input_queue_name - Name of SQS to read input messages from
|
|
output_queue_name - Name of SQS to write output messages to
|
|
extra_data - additional name-value pairs that will be passed as
|
|
userdata to the newly launched instance. These should
|
|
be of the form "name=value"
|
|
The -r option reloads the Python module to S3 without launching
|
|
another instance. This can be useful during debugging to allow
|
|
you to test a new version of your script without shutting down
|
|
your instance and starting up another one.
|
|
The -w option tells the script to run synchronously, meaning to
|
|
wait until the instance is actually up and running. It then prints
|
|
the IP address and internal and external DNS names before exiting.
