Version control is an essential part of the DevOps toolkit. Learn the basics of version control and why its important.
- [Instructor] In this section, we'll be talking…about version control and how to use it with Puppet.…Version control software allows you…to track changes in a set of files over time.…It's widely used in software development…and is becoming very common, even in pure ops teams.…Puppet defines your infrastructure as code,…so we can use version control to track those changes.…If you were going to try to keep track…of changes in a set of files, you might first…make a backup copy of the entire directory.…That way, if you needed to compare the original…or revert some changes, you'd be sure you have a copy.…
The problem is, it's difficult to keep track…of a lot of changes this way, and, as you work,…you'll need to keep making copies of your documents,…which leads to a lot of waste.…And if you wanted to collaborate…on a document with colleagues,…this way of doing it becomes pretty difficult.…Version control solves this problem…by offering a way to track every change that's made.…We'll be using Git, so I'll focus on how it works.…
