Hello There!
A quick note before you proceed with the demos. If you are following this course from the first course, and if you have setup your environment using CentOS, you may continue to use the same environment.
The Demos in this course are developed on a Debian Environment. So you may need to adjust/modify some commands used in the playbooks and demos to work on your version of Operating System.
For example you may need to modify package manager commands from apt to yum for CentOS.
I originally used Debian for my setup, however, most students found CentOS easier to setup. So please make the necessary changes in your version of OS.
I am working on a better and improved lab experience which will be more real, fun and challenging! Until that is ready, my apologies for the inconvenience caused. Hope you enjoy this course!
