How to automate Ubuntu installation?

Question

ubuntu

Hello.
I regularly have to install ubuntu server, and all the time by hand, which takes a lot of time.
When installing, you need a specific disk slicing, and it can be different (for example, RAID 1, or 10, root 30 sometimes 50, etc., etc., I would like to somehow set these parameters on the fly).
How can you automate installation? Build your iso or some script?
Everything is further complicated by the fact that everything is installed at different hosters and has different admin panels.

Answer 1

Hosters? Admin panels?
If you are installing from your iso image, you can do an unattended installation (google preseed). If from distribution kits of hosters through LC - it is problematic, if only to repartition again after installation.

Answer 2

The fastest option would be to install by hand. Installation 10-15 minutes.
You mark up disks always in different ways, with the network the same story. You can't think of anything.
