.. 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 ``__. .. 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 `.

Read :doc:`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 ` to support additional services, features, and configuration not present in base devstack.
