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.
