Hello, I was trying to understand the end result flow of the Airavata with Cloud Orchestrator and had the following question:-
Once the cluster has been setup, as we discussed, an ansible or some configuration management tool would boostrap and configure mesos. Which component in Airavata would host and call the ansible script and what event would trigger it? Thanks.
