All-In-One installer

Registered by Emilien Macchi on 2018-03-29

We had the discussion for the first time as a community during the PTG in Dublin.
The idea is to provide a "single" (or small count) node installer for TripleO.
A kind of a "Packstack" replacement... but not a parity replacement.
Just a similar idea which would support containers.

Benefits:
* composable services (any set of services)
* can create a set of pre-defined roles to make it easy for devs
* a condensed single node environment.
* lower bar to be able to dev/test TripleO. Single machine: VM. Simpler tooling
* alternate interface (playbooks) could allow users to run the installer itself in a container. Small footprint installer. Container -> generates Ansible playbooks. Which you launch on a host.

The user would have to run:
openstack tripleo deploy --standalone --config all_in_one.yaml

on a fresh centos7 instance and it would deploy OpenStack in less than one hour... this could be a target.
