The order of the steps were a bit confusing for the first timers in the devstack document. So, changed the order of installation steps to make it clear. Change-Id: Ifaa051887dab95719b9ca5d1b2fbe2f5f549d269 Closes-Bug: #1627939

.. 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

|
DevStack is a series of extensible scripts used to quickly bring up a
|
|
complete OpenStack environment based on the latest versions of
|
|
everything from git master. It is used interactively as a development
|
|
environment and as the basis for much of the OpenStack project's
|
|
functional testing.
|
|
|
|
The source is available at
|
|
`<https://git.openstack.org/cgit/openstack-dev/devstack>`__.
|
|
|
|
.. warning::
|
|
|
|
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
|
|
===========
|
|
|
|
Install Linux
|
|
-------------
|
|
|
|
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.
|
|
|
|
If you do not have a preference, Ubuntu 16.04 is the most tested, and
|
|
will probably go the smoothest.
|
|
|
|
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
|
|
|
|
::
|
|
|
|
$ adduser stack
|
|
|
|
Since this user will be making many changes to your system, it should
|
|
have sudo privileges:
|
|
|
|
::
|
|
|
|
$ echo "stack ALL=(ALL) NOPASSWD: ALL" >> /etc/sudoers
|
|
$ su stack
|
|
|
|
Download DevStack
|
|
-----------------
|
|
|
|
::
|
|
|
|
$ git clone https://git.openstack.org/openstack-dev/devstack
|
|
$ cd 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 at the root of the
|
|
devstack git repo.
|
|
::
|
|
|
|
[[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.
|
|
|
|
Start the install
|
|
-----------------
|
|
|
|
::
|
|
|
|
./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!
|
|
-------
|
|
|
|
You now have a working DevStack! Congrats!
|
|
|
|
Your devstack will have installed ``keystone``, ``glance``, ``nova``,
|
|
``cinder``, ``neutron``, and ``horizon``. Floating IPs will be
|
|
available, guests have access to the external world.
|
|
|
|
You can access horizon to experience the web interface to
|
|
OpenStack, and manage vms, networks, volumes, and images from
|
|
there.
|
|
|
|
You can ``source openrc`` in your shell, and then use the
|
|
``openstack`` command line tool to manage your devstack.
|
|
|
|
You can ``cd /opt/stack/tempest`` and run tempest tests that have
|
|
been configured to work with your devstack.
|
|
|
|
You can :doc:`make code changes to OpenStack and validate them
|
|
<development>`.
|
|
|
|
Going further
|
|
-------------
|
|
|
|
Learn more about our :doc:`configuration system <configuration>` to
|
|
customize devstack for your needs. Including making adjustments to the
|
|
default :doc:`networking <networking>`.
|
|
|
|
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>`.
