问题
Right now I am using the Auto Scaling Command Line Tool to launch a new EC2 instance once per day and run a script that terminates itself upon completion. Now I need to do the same thing with a different script, but this one requires several Python modules to be installed. Therefore, I would like to schedule the start/stop of a single, existing instance rather than the launch/termination of a brand new instance. I've scoured Amazon's documentation/blogs but I can't determine if this functionality is supported with Autoscaling. How could this be accomplished?
回答1:
Its not supported with autoscaling. If you want to keep doing what you are currently doing. You could install the python modules with a cloud init script.
You can also start/stop an existing instance with the command line tools, just not the autoscaling ones.

My eventual solution was to set up an instance the way I wanted and then create an AMI from it. My autoscaling setup then starts/stops an instance of that AMI.
