I used to have a fille with every cli command and notes on how each thing was set up. When I had to reinstall it from scratch it took all day going through lots of manual steps and remembering how it should all go.
Recently I converted the whole thing to Ansible. Now I could rebuild my entire system on a brand new OS installation with one command that completes in minutes. It’s all modular and I can add new services easily whether they are docker containers or scripts or whatever. If I ever break anything, it will reset everything to its intended state and leave it alone otherwise. And it’s free and pretty easy to learn and start using.
Plus I use git along with it for version control, so I can always revert to any previous configuration instantly.
TBH its not the users fault, the documentation is always like (click here for docker install instructions, or if you don’t want docker click here for bare metal instructions) and the latter is just apt get and some config edits.
