How to remotely install programs on multiple ubuntu computers?

Question

System administration

There are 25 computers with Ubuntu, how can I remotely install anything on them? There is access to all computers, all are on the same network. For example, you need to install remina (rdp client) on 25 computers, how to do this with a minimum of effort. When googling, I did not find the answer, not even close.

Answer 1

ansible/salt/chef/puppet. Especially if the task is not one-time.

Answer 2

The simplest one is definitely dsh , which is as dumb and reliable as the corner of a house.
More complex, but more functional, are all sorts of orchestration systems, such as the above ansible, salt and other puppets.
See what you need.
Well, that is, directly your task with dsh is solved by exactly one command, if the user key is previously decomposed into machines. With ansible, you need to write a script for the playbook, that is, a little more time. But, at the same time, if you need to constantly control these machines, then once you describe the playbook for them, what should be there, what users should be, and so on, you can steer them with one command.
Choose for yourself what you need.
