Hi Mathieu, Thanks for bringing up the topic. There are several efforts currently in progress which should lead to solving the problems you're describing. We are working on introducing CLI commands which would perform the deployment configuration operations on deployment plan in Swift. This is a main step to finally reach CLI and GUI compatibility/interoperability. CLI will perform actions to configure deployment (roles, networks, environments selection, parameters setting etc.) by calling Mistral workflows which store the information in deployment plan in Swift. The result is that all the information which define the deployment are stored in central place - deployment plan in Swift and the deploy command is turned into simple 'openstack overcloud <planName> deploy'. Deployment plan then has plan-environment.yaml which has the list of environments used and customized parameter values, roles-data.yaml which carry roles definition and network-data.yaml which carry networks definition. The information stored in these files (and deployment plan in general) can then be treated as source of information about deployment. The deployment can then be easily exported and reliably replicated.
Here is the document which we put together to identify missing pieces between GUI,CLI and Mistral TripleO API. We'll use this to discuss the topic at PTG this week and define work needed to be done to achieve the complete interoperability.  Also there is a pending patch from Steven Hardy which aims to remove CLI specific environments merging which should fix the problem with tracking of the environments used with CLI deployment.   https://gist.github.com/jtomasek/8c2ae6118be0823784cdafebd9c0edac (Apologies for inconvenient format, I'll try to update this to better/editable format.
