Manage spot (preemptible) instances in a cloud environment. The code will query for the existence of running instances, retire from the condor queue servers that have been alive for a while (to prevent jobs running when machines are pulled down), will pull down idle machines and finally create new ones.

The best is to install inside a virtualenv

python3 -m venv spotmanager
cd spotmanager
source bin/activate
pip install --upgrade pip
pip install wheel
pip install git+https://github.com/egede/spotmanager.git

The code can run from the controller script. Do

controller --help

to see the options. Almost for sure code will need to be modified to suit an individual use.
