Many applications have a data directory, usually due to having an embedded database. For the set I work with, this includes Red Hat IdM/FreeIPA, CloudForms/ManageIQ, Ansible Tower/AWX, and OpenShift/Kubernetes. Its enough of a pattern that I have Ansible code for pairing a set of newly allocated partitions with a set of previously built virtual machines.
Part of my Job is making sure our customers can run our software in Public clouds. Recently, I was able to get CloudForms Management Engine (CFME) to deploy to Azure. Once I got it done manually, I wanted to automate the deployment, and that means Ansible. Turns out that launching custom images from Ansible is not support int the current GA version of the Azure modules, but has been implemented upstream.
