In this tutorial, you will learn how to deploy OpenStack using DevStack on Ubuntu 22.04\/Ubuntu 20.04. There are different methods\/tools<\/a> that you can use to deploy OpenStack. Such include Ansible-kolla, openstack-ansible e.t.c. We will use DevStack to deploy a single node OpenStack on Ubuntu 22.04\/Ubuntu 20.04. DevStack<\/a> is a set of scripts and utilities to quickly deploy an OpenStack cloud from git source trees.<\/em><\/p>\n\n\n\n

Deploy OpenStack using DevStack on Ubuntu<\/h2>\n\n\n\n

In order to deploy OpenStack using DevStack, below are our system resources assigned to the vms. Of course if you have the capability to use more, please do!<\/p>\n\n\n\n

Item<\/strong><\/td>Specifics<\/strong><\/td><\/tr>
Linux System<\/td>Minimal Ubuntu 22.04\/20.04 VM running on VirtualBox<\/td><\/tr>
Processors<\/td>4 vCPUs<\/td><\/tr>
RAM<\/td>8 GB<\/td><\/tr>
Disk<\/td>50 GB<\/td><\/tr>
Internet Access<\/td>Yes<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

Install Minimal Linux System<\/h3>\n\n\n\n

You need deploy a minimal version of the Linux system you want to deploy OpenStack on since DevStack will install all the required packages. In this tutorial, we are using Ubuntu 22.04\/20.04 servers running on VirtualBox.<\/p>\n\n\n\n

Run System Update\/Upgrade<\/h3>\n\n\n\n

Once the system is up, you can update the system package repos;<\/p>\n\n\n\n

sudo apt update -y<\/code><\/pre>\n\n\n\n
sudo apt upgrade -y && sudo systemctl reboot -i<\/code><\/pre>\n\n\n\n
Create an Optional Deployment User<\/h3>\n\n\n\n
To deploy OpenStack using DevStack, you need to optionally have a standard user account, with passwordless sudo rights on your system.<\/p>\n\n\n\n
To create a user account, run the command below;<\/p>\n\n\n\n
sudo useradd -m -s \/bin\/bash cloud-admin<\/code><\/pre>\n\n\n\n
Give the user passwordless sudo rights;<\/p>\n\n\n\n
sudo visudo -f \/etc\/sudoers.d\/cloud-admin<\/code><\/pre>\n\n\n\n
Enter the line below<\/p>\n\n\n\n
cloud-admin ALL = NOPASSWD: ALL<\/code><\/pre>\n\n\n\n
Save and exit the file.<\/p>\n\n\n\n
Clone DevStack Github Repository<\/h3>\n\n\n\n
Switch to deployment user created above and clone the DevStack Github repository which contains a script that installs OpenStack and templates for configuration files<\/em>;<\/p>\n\n\n\n
sudo -u cloud-admin -i<\/code><\/pre>\n\n\n\n
git clone https:\/\/opendev.org\/openstack\/devstack<\/code><\/pre>\n\n\n\n
ls -1 devstack<\/code><\/pre>\n\n\n\n
clean.sh\nCONTRIBUTING.rst\ndata\ndoc\nextras.d\nfiles\nfunctions\nfunctions-common\nFUTURE.rst\ngate\nHACKING.rst\ninc\nlib\nLICENSE\nMakefile\nopenrc\nplaybooks\nREADME.rst\nroles\nrun_tests.sh\nsamples\nstackrc\nstack.sh\ntests\ntools\ntox.ini\nunstack.sh\n<\/code><\/pre>\n\n\n\n
Configure DevStack for OpenStack Deployment<\/h3>\n\n\n\n
To begin with, you need to create to define\/create passwords for some OpenStack services such Horizon, database, RabbitMQ and services password. These passwords need to be defined on the local.conf file under the root directory of the DevStack repository. If you do not define these passwords, you will be prompted by the installer to enter them during the installation of OpenStack.<\/p>\n\n\n\n
Thus, navigate to the devstack Github repository directory;<\/p>\n\n\n\n
cd devstack<\/code><\/pre>\n\n\n\n
vim local.conf<\/code><\/pre>\n\n\n\n
Enter the settings below, and update the value of each variable to your preferred password;<\/p>\n\n\n\n
[[local|localrc]]\nADMIN_PASSWORD=YourPasswordHere<\/strong>\nDATABASE_PASSWORD=$ADMIN_PASSWORD\nRABBIT_PASSWORD=$ADMIN_PASSWORD\nSERVICE_PASSWORD=$ADMIN_PASSWORD<\/code><\/pre>\n\n\n\n
Note that we used same password for all those services in this example setup.<\/p>\n\n\n\n
Similarly, define the OpenStack Host IP address;<\/p>\n\n\n\n
HOST_IP=192.168.56.124<\/code><\/pre>\n\n\n\n
Change that to your system IP that will allow you to access OpenStack.<\/p>\n\n\n\n
Save and exit the file.<\/p>\n\n\n\n
In its simplest setup, the above configurations are enough to get you started with the deployment of single node OpenStack for a proof of concept on Ubuntu 22.04 or Ubuntu 20.04.<\/p>\n\n\n\n
You can check the sample local.conf configuration file under the devstack\/samples\/<\/code><\/strong> directory.<\/p>\n\n\n\n
Deploy OpenStack using DevStack<\/h3>\n\n\n\n
All you need to do to deploy OpenStack using DevStack is to execute the DevStack script, stack.sh<\/code><\/strong> and let it perform its magics!<\/p>\n\n\n\n
.\/stack.sh<\/code><\/pre>\n\n\n\n
In the meantime, it is time for you to get up and make coffee!!<\/p>\n\n\n\n
When the script completes successfully, you will see such an installation summary output;<\/p>\n\n\n\n
