Eh you can do the same thing (or close enough) with a bash install script on a "stock" linux system and then a docker set up with the applications that that you want. Or with ansible. it really depends on the end goal. Not everyone needs every single bit to be the same. Or you can just image a drive. It depends on the end goal and often multiple solutions will get you there.

These are the nasty solutions I have to deal with at work all the time and my entire job consists of handling things when the "quick" bash cloud init script that someone wrote and various people have made additions to over the years goes wrong.

Bash scripts fail at this task because they are generally not convergent. Ansible makes a basic effort at being convergent, but most of the scripts I've seen are extremely naive about the ways in which a configuration can diverge.

moreover, you can also use docker digest instead of tags, that is: instead of docker pull postgresql:11 you can do docker pull postgresql@sha:xxxx....
