What is the easiest way to deploy software on the customer's hardware?

Question

Software Deployment

Colleagues, good afternoon!
For my own self-development, I decided to clarify the question. On the customer's hardware, it is necessary to deploy an OS (most often Astra Linux 1.4-1.5 or Windows), configure rights, DBMS, networking, and so on and so forth. We install from installers or packages, we roll the settings with scripts, where we can. We try to automate everything, but all the same, the process takes a lot of time for our implementers and is associated with errors (there is a wiki with a sequence of actions, but it happens that they forgot to roll the script, issue rights or something else). I would like to avoid such mistakes. A small moment, at the workplace before the departure of the implementers, a stand is created with an absolutely similar composition, everything is checked on it and then a go-ahead is given to leave. Actually, the question is, how can you simplify the deployment process and reduce the required time and number of errors?
There was an idea to immediately bring the image of the OS to the customer (take it from the working stand) and deploy it, is it real, are there any pitfalls? I heard about Docker many times, but never used it, can it be used in our situation?
I would be grateful for advice. Thank you.

Answer 1

There are more than enough options for Linux systems - ansible, Chef, Puppet, Salt.
For Windows, everything is much harder, you did not describe what Windows is for and how critical it is, but if it is possible to remove it from the bundle, then remove it and life will become easier.
If there is no way to remove Windows from the chain, then it's time to remember about MSI packages and start doing them (I can recommend Advanced installer).

Answer 2

Debian, like any Unix, can be transferred to another computer by copying and restoring all sections of the screw, even if the hardware does not match. He does not care about drivers, this is not Windows.
