The existing feature branch capability in CDAF (Git only, entry.ps1/entry.sh) has been based on docker-compose, for stand-up, test and tear-down environments based on feature branches. For some organizations, where containers are not feasible, i.e. system complexity, proprietary software, a limited number on perpetual environments are available.
The CDAF extension (2.4.5) allows for the targeting of one or more environments, based on branch name prefix (definition file is feature-branch.properties).
Important note: beware of potential environment drift over time as different environments receive different updates.
