In our examples, we are going to create a file that will essentially be an .iso
image and behave like a CD-ROM connected to the booting machine. Cloud-init knows how to handle a situation like this, and will mount the file, extract all the scripts, and run them in a predetermined order, as we already mentioned when we explained how the boot sequence works (check the Understanding cloud-init architecture section earlier in this chapter).
In essence, what we have to do to get the whole thing running is to create an image that will get connected to the cloud template, and that will provide all the data files to the cloud-init scripts inside the template. This is a three-step process:
The most complicated part...
Change the font size
Change margin width
Change background colour
