In the root of the repository are the general kickstarts in use that any
|
||||
user can pick up, use, or modify to their liking to make their own Rocky
|
||||
Linux live images. For those who are curious, in the `live` directory are
|
||||
the split parts that make the live kickstarts what they are, which you can
|
||||
use `ksflatten` on if you so choose.
|
||||
Linux live images, cloud images, and so on. These kickstarts are generated
|
||||
by templates that live in the various directories in this repository.
|
||||
|
||||
* `cloud` -> Cloud image templates
|
||||
* `live` -> Live image templates
|
||||
* `container` -> Container image templates
|
||||
|
||||
These kickstarts are generated using `ksflatten`. Changes made to the
|
||||
kickstarts generally match between the templates and the full kickstarts
|
||||
in the root.
|
||||
|
||||
For SIG/Core's usage, we use the `live` area as a "working" directory,
|
||||
where we use the split parts in our automation for the images and the
|
||||
pre-flattened versions are there for the convenience of all users.
|
||||
pre-flattened versions are there for the convenience of all users. This
|

is easier than using the pre-made ones in empanadas.

# 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
|
||||
```
