USER STORY STATEMENT: As a 12 Factor App Developer, I need to run Admin Process (XII) tasks as one-off processes.

User Story | Enabler Task

STORY: As a 12 Factor App Developer, I need to run Admin Process (XII) tasks as once-off (standalone) processes in an identical environment as the regular long-running processes of the app so that these tasks can be run against the same release, using the same codebase, dependency isolation and config of that release.

In the Context of: 
  - Running administration scripts or management tasks in the same environment as the app runtime
As a: As a 12 Factor App Developer
I/We want: I need to run admin/management process tasks as once-off (standalone) processes
In the/an: identical environment as the regular long-running processes of the app, i.e. the `release`.
And: preferablly use a REPL shell environment that ships with the technologies involved.
Because: these tasks must  
  i) run against a release (V)
 ii) use the same codebase (I) .. run against that release (V)
iii) use the same config (III) .. run against that release (V)
iv) align with dependency isolotion (II) of the release
 v) across same deployed process types (VI)
vi) for once off scripts be easy to run in REPL shells.

Type of: Enabler Task

Defintion: Process Formation

The array of processes that are used to do the app’s regular business (such as handling web requests) as it runs.
i.e.:

• Running database migrations (e.g. manage.py migrate in Django)
• Running a console (also known as a REPL shell) to
  i) Run arbitrary code or
  ii) inspect the app’s models against the live database.
• Running one-time scripts committed into the app’s repo
