update front page of devstack docs
The devstack docs have gotten a bit meandering so even the quick start guide doesn't get you to a working setup without referencing other pages. This attempts to pull this back in a bit. Change-Id: I608331cbdae9cbe4f3e8bd3814415af0390a54d0

All-In-One Single VM
|
||||
--------------------
|
||||
|
||||
Run :doc:`OpenStack in a VM <guides/single-vm>`. The VMs launched in your cloud will be slow as
|
||||
they are running in QEMU (emulation), but it is useful if you don't have
|
||||
spare hardware laying around. :doc:`[Read] <guides/single-vm>`
|
||||
|
||||
All-In-One Single Machine
|
||||
-------------------------
|
||||
|
||||
Run :doc:`OpenStack on dedicated hardware <guides/single-machine>` This can include a
|
||||
server-class machine or a laptop at home.
|
||||
:doc:`[Read] <guides/single-machine>`
|
||||
|
||||
All-In-One LXC Container
|
||||
-------------------------
|
||||
|
||||
Run :doc:`OpenStack in a LXC container <guides/lxc>`. Beneficial for intermediate
|
||||
and advanced users. The VMs launched in this cloud will be fully accelerated but
|
||||
not all OpenStack features are supported. :doc:`[Read] <guides/lxc>`

DevStack
|
||||
========
|
||||
.. Documentation Architecture for the devstack docs.
|
||||
|
||||
It is really easy for online docs to meander over time as people
|
||||
attempt to add the small bit of additional information they think
|
||||
people need, into an existing information architecture. In order to
|
||||
prevent that we need to be a bit strict as to what's on this front
|
||||
page.
|
||||
|
||||
This should *only* be the quick start narrative. Which should end
|
||||
with 2 sections: what you can do with devstack once it's set up,
|
||||
and how to go beyond this setup. Both should be a set of quick
|
||||
links to other documents to let people explore from there.

DevStack is a series of extensible scripts used to quickly bring up a

development environment and as the basis for much of the OpenStack

project's functional testing.

DevStack will make substantial changes to your system during
|
||||
installation. Only run DevStack on servers or virtual machines that
|
||||
are dedicated to this purpose.
|
||||
|
||||
Quick Start
|
||||
-----------
|
||||
===========
|
||||
|
||||
#. Select a Linux Distribution
|
||||
|
||||
Only Ubuntu 14.04 (Trusty), Fedora 22 (or Fedora 23) and CentOS/RHEL
|
||||
7 are documented here. OpenStack also runs and is packaged on other
|
||||
flavors of Linux such as OpenSUSE and Debian.
|
||||
|
||||
#. Install Selected OS
|
||||
|
||||
In order to correctly install all the dependencies, we assume a
|
||||
specific minimal version of the supported distributions to make it as
|
||||
easy as possible. We recommend using a minimal install of Ubuntu or
|
||||
Fedora server in a VM if this is your first time.
|
||||
|
||||
#. Download DevStack
|
||||
|
||||
::
|
||||
|
||||
git clone https://git.openstack.org/openstack-dev/devstack
|
||||
|
||||
The ``devstack`` repo contains a script that installs OpenStack and
|
||||
templates for configuration files
|
||||
|
||||
#. Configure
|
||||
|
||||
We recommend at least a :ref:`minimal-configuration` be set up.
|
||||
|
||||
#. Add Stack User
|
||||
|
||||
Devstack should be run as a non-root user with sudo enabled
|
||||
(standard logins to cloud images such as "ubuntu" or "cloud-user"
|
||||
are usually fine).
|
||||
|
||||
You can quickly create a separate `stack` user to run DevStack with
|
||||
|
||||
::
|
||||
|
||||
devstack/tools/create-stack-user.sh; su stack
|
||||
|
||||
#. Start the install, this will take a few minutes.
|
||||
|
||||
::
|
||||
|
||||
cd devstack; ./stack.sh

DevStack Documentation
|
||||
======================
|
||||
|
||||
Overview
|
||||
--------
|
||||
|
||||
:doc:`An overview of DevStack goals and priorities <overview>`
|
||||
|
||||
Configuration
|
||||
Install Linux
|
||||
-------------
|
||||
|
||||
:doc:`Configuring and customizing the stack <configuration>`
|
||||
Start with a clean and minimal install of a Linux system. Devstack
|
||||
attempts to support Ubuntu 14.04/16.04, Fedora 23/24, CentOS/RHEL 7,
|
||||
as well as Debian and OpenSUSE.
|
||||
|
||||
Plugins
|
||||
If you do not have a preference, Ubuntu 16.04 is the most tested, and
|
||||
will probably go the smoothest.
|
||||
|
||||
Download DevStack
|
||||
-----------------
|
||||
|
||||
::
|
||||
|
||||
git clone https://git.openstack.org/openstack-dev/devstack
|
||||
|
||||
The ``devstack`` repo contains a script that installs OpenStack and
|
||||
templates for configuration files
|
||||
|
||||
Create a local.conf
|
||||
-------------------
|
||||
|
||||
Create a ``local.conf`` file with 4 passwords preset
|
||||
|
||||
::
|
||||
|
||||
[[local|localrc]]
|
||||
ADMIN_PASSWORD=secret
|
||||
DATABASE_PASSWORD=$ADMIN_PASSWORD
|
||||
RABBIT_PASSWORD=$ADMIN_PASSWORD
|
||||
SERVICE_PASSWORD=$ADMIN_PASSWORD
|
||||
|
||||
This is the minimum required config to get started with DevStack.
|
||||
|
||||
Add Stack User
|
||||
--------------
|
||||
|
||||
Devstack should be run as a non-root user with sudo enabled
|
||||
(standard logins to cloud images such as "ubuntu" or "cloud-user"
|
||||
are usually fine).
|
||||
|
||||
You can quickly create a separate `stack` user to run DevStack with
|
||||
|
||||
::
|
||||
|
||||
devstack/tools/create-stack-user.sh; su stack
|
||||
|
||||
Start the install
|
||||
-----------------
|
||||
|
||||
::
|
||||
|
||||
cd devstack; ./stack.sh
|
||||
|
||||
This will take a 15 - 20 minutes, largely depending on the speed of
|
||||
your internet connection. Many git trees and packages will be
|
||||
installed during this process.
|
||||
|
||||
Profit!
|
||||
-------
|
||||
|
||||
:doc:`Extending DevStack with new features <plugins>`
|
||||
You now have a working DevStack! Congrats!
|
||||
|
||||
FAQ
|
||||
---
|
||||
Your devstack will have installed ``keystone``, ``glance``, ``nova``,
|
||||
``cinder``, ``neutron``, and ``horizon``. Floating IPs will be
|
||||
available, guests have access to the external world.
|
||||
|
||||
:doc:`The DevStack FAQ <faq>`
|
||||
You can access horizon to experience the web interface to
|
||||
OpenStack, and manage vms, networks, volumes, and images from
|
||||
there.
|
||||
|
||||
Contributing
|
||||
------------
|
||||
You can ``source openrc`` in your shell, and then use the
|
||||
``openstack`` command line tool to manage your devstack.
|
||||
|
||||
:doc:`Pitching in to make DevStack a better place <hacking>`
|
||||
You can ``cd /opt/stack/tempest`` and run tempest tests that have
|
||||
been configured to work with your devstack.
|
||||
|
||||
Going further
|
||||
-------------
|
||||
|
||||
Learn more about our :doc:`configuration system <configuration>` to
|
||||
customize devstack for your needs.
|
||||
|
||||
Read :doc:`guides <guides>` for specific setups people have (note:
|
||||
guides are point in time contributions, and may not always be kept
|
||||
up to date to the latest devstack).
|
||||
|
||||
Enable :doc:`devstack plugins <plugins>` to support additional
|
||||
services, features, and configuration not present in base devstack.
|
||||
|
||||
Get :doc:`the big picture <overview>` of what we are trying to do
|
||||
with devstack, and help us by :doc:`contributing to the project
|
||||
<hacking>`.
