# Cloud Templates
|
|
|
|
This directory contains templated versions of the cloud images. This is
|
|
extremely useful for us to be able to create more variants or modify
|
|
all variants at once if need be.
|
|
|
|
The general guidelines/ideas work like this:
|
|
|
|
* Start with a basic name, such as `rocky-${provider}-${variant}.ks`
|
|
* Optionally create additional kickstarts, such as an additional packages file
|
|
* Include the very base as necessary:
|
|
|
|
* rocky-cloud-base.ks
|
|
* rocky-cloud-parts-base.ks or rocky-cloud-parts-lvm.ks
|
|
|
|
* Include other customizations from another kickstart as necessary, such as an additional packages kickstart
|
|
* bootloader configuration and then final %post ... %end section
|
|
|
|
The most basic example of our most basic generic cloud image goes like this. See comments for details.
|
|
|
|
```
|
|
# rocky-genclo-base.ks
|
|
|
|
# Imports the absolute base for the cloud images. This is general setup settings.
|
|
%include rocky-cloud-base.ks
|
|
|
|
# Imports partition scheme and creation for the image. This is non-LVM.
|
|
%include rocky-cloud-parts-base.ks
|
|
|
|
# Imports base packages that all cloud images are expected to have
|
|
%include rocky-cloud-base-packages.ks
|
|
|
|
# bootloader information, each cloud will have different settings, so better we put it here.
|
|
bootloader --append="console=ttyS0,115200n8 no_timer_check crashkernel=auto net.ifnames=0" --location=mbr --timeout=1
|
|
|
|
# Anything else can go here that isn't fulfilled by custom or base templates.
|
|
# This can be repos if needed.
|
|
|
|
# the final post section is done here (we've removed all of it for the sake of the example)
|
|
%post --erroronfail
|
|
. . .
|
|
%end
|
|
```
|
|
|
|
At the end, you would run run ksflatten, and you now have a customized kickstart.
|
|
|
|
```
|
|
ksflatten -c rocky-genclo-base.ks -o Rocky-X-GenericCloud-Base.ks
|
|
```
