Dr. Jens Harbott de41a18909 Update distros on the docs start page
Centos 7 is no longer supported, replace with Centos 8. Also Debian
hasn't been working for some time and progress in fixing it has stalled,
so drop it for now.

.. 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
========
.. image:: assets/images/logo-blue.png
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://opendev.org/openstack/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 the two latest LTS releases of Ubuntu, the
latest/current Fedora version, CentOS/RHEL 8 and OpenSUSE.
If you do not have a preference, Ubuntu 18.04 (Bionic Beaver) is the
most tested, and will probably go the smoothest.
Add Stack User (optional)
-------------------------
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).
If you are not using a cloud image, you can create a separate `stack` user
to run DevStack with
.. code-block:: console
$ sudo useradd -s /bin/bash -d /opt/stack -m stack
Since this user will be making many changes to your system, it should
have sudo privileges:
.. code-block:: console
$ echo "stack ALL=(ALL) NOPASSWD: ALL" | sudo tee /etc/sudoers.d/stack
$ sudo su - stack
Download DevStack
-----------------
.. code-block:: console
$ git clone https://opendev.org/openstack/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 four passwords preset at the root of the
devstack git repo.
.. code-block:: ini
[[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.
.. note:: There is a sample :download:`local.conf </assets/local.conf>` file
under the *samples* directory in the devstack repository.
Start the install
-----------------
.. code-block:: console
$ ./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``,
``placement``, ``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.
Use devstack in your CI with :doc:`Ansible roles <zuul_roles>` and
:doc:`Jobs <zuul_jobs>` for Zuul V3. Migrate your devstack Zuul V2 jobs to Zuul
V3 with this full migration :doc:`how-to <zuul_ci_jobs_migration>`.
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>`.
