In this Lab, we are going to learn to use the nova compute CLI in order to launch an instance instead of from the web Dashboard. We are first going to connect to our instance in the Dashboard in order to learn how to download from any OpenStack environment what is called the OpenStack RC file. An OpenStack RC file is used to set environment variables in our Linux terminal session in order to set project-specific credentials for the OpenStack CLI services such as Compute, Image, and Identity services.
