Cloud computing has become very popular recently. Part of the reason for this popularity is that it provides great flexibility allowing complete control of the computing environment. In addition the environment can be copied, backed up, created and recreated in an automated way. In this lesson we will take the next step in learning to use OpenStack clouds and introduce the OpenStack Command Line Interface (CLI). This CLI allows you to perform the same tasks as you would normally with on the OpenStack Dashboard, but from the command line allowing some amount of automation through scripts. In addition the OpenStack CLI allows you to gain information and perform tasks that you can not simply by using the OpenStack dashboard.
This course assumes you have taken our Introduction to cloud course or have similar experience.
Prerequisites
- Make sure you have performed the required setup before the workshop begins.
- You will need to have your own laptop or desktop on which you can install the required software (see the setup for more details).
- Students should be comfortable working with computer file systems. They should know how to create and delete directories and files on their own personal computer.
- Software Carpentry’s Unix Shell, or similar experience is required.
