Is it possible to git control the configuration of a web server running Ubuntu?

Question

git

Question: Is it possible to make git control the web server configuration?
If some daemon stops working with an incorrect configuration, will this help fix the problem faster? - I think yes!
If there is a crash during the download - is it possible to restore the old configuration through git?
If there is a good example on the net - please provide a link!
Why do I need it? - I want to emulate a bunch of servers on virtualbox for load balancing, and in case of unsuccessful settings - rollback via git
An example of working with etckeeper

Answer 1

In virtualbox, you can rollback through snapshots. much more convenient, especially for those who do not understand the git (the author, judging by the questions, is among them)
and so - everything is possible. etckeeper or handles

Answer 2

Try Docker. Just create a Dockerfile, add configs, users, groups to the container (you can make your own, or take any you like as a basis), run applications, set up network connections. And in which case - rebuild again, and it takes seconds.
