Introduction
DevStack is like a small preconfigured OpenStack cloud.To run it, you don't need to have your own datacenter, the average laptop would be enough for this purpose.
You can install DevStack just to taste OpenStack services, but it's mainly intended to be used in development process by OpenStack developers.
In this guide I will help you to install DevStack in a way suitable with further development process. After completing the guide you will know how to start and stop DevStack cloud and access it via OpenStack Dashboard web interface.
Instead of just providing instructions, I'll also tell you some important details and describe the obstacles you might be facing during the process of installing DevStack. When I was getting started with DevStack, I was in need of such guide. So now I'm writing this guide like for the past me.
