Introduction to Ansible Transcripts
Lecture: Using Data
0:00 In this chapter, we learned how
0:01 to take our static playbooks and make them dynamic
0:04 using the different forms of data that are available.
0:06 Of course, we have variables that allow us to
0:08 punch in values into our tasks and roles
0:11 and when we pull any hard coded values out of our tasks
0:14 and separate them into variables
0:15 it makes our playbooks and our roles more reusable.
0:18 Also took a look at how to read environment variables.
0:20 You don't want to store all your variables in files
0:23 and templates can be input data for configuration files
0:26 or README files, and these will be incredibly handy
0:29 as wet set up many services in future chapters
0:31 such as getting our web server configuration established
0:34 and much of our data can be sensitive
0:36 so we want to make sure that we encrypt it
0:38 so we don't accidentally expose passwords
0:40 or other important information
0:41 when we check our files in diversion control.
0:43 While we didn't bring these up
0:44 as core concepts advanceable in previous chapters
0:47 these are all going to be very important
0:49 and we'll work with them as we configure a server
0:51 and deploy a Python application in later chapters.
