Quick Guide: Install OpenStack DevStack

Hi!👋 I'm excited to share how I set up OpenStack using DevStack on local machine. If you’re just getting started with OpenStack, this guide might help you spin up your own testing environment.

⚠️ Disclaimer: This is a minimal, all-in-one installation intended for development and testing purposes only. Do not use this setup in production environments.

What is DevStack?

DevStack is a series of extensible scripts used to quickly bring up a complete OpenStack environment for development or testing purposes. It’s not recommended for production use, but it's perfect for labs and learning.

Why Use DevStack?

DevStack is a great way to:

Learn OpenStack hands-on
Test and experiment with OpenStack components
Set up a local cloud lab quickly

But again, it’s not designed for production workloads, so test it as your cloud playground.

My System Info

Before diving in, I’ve already installed a VM on my local machine. Here’s the OS I used:

Setup Steps

1. Update the system

Make sure your packages are up to date:

sudo apt-get update -y

2. Clone my DevStack setup repo

I've uploaded a custom DevStack configuration script to GitHub. Feel free to clone and use it.

git clone https://github.com/linnlattoo-cloud/devstack.git
cd devstack

3. Make the setup script executable

chmod +x devstack_setup.sh

4. Optional: Customize your setup

You can change passwords for:

Database
admin
service
RabbitMQ

Just edit the local.conf file by using vim editor or nano inside the repo before starting the install.

5. Run the setup script

This will download and install OpenStack and take 20–30 minutes.

./devstack_setup.sh

Accessing OpenStack

Once the setup is done, you can log in to the OpenStack dashboard (Horizon) (http://your-server(vm)-ip/dashboard) using the admin user and the admin password you defined in local.conf.
