Imogen is a system image generator, primarily intended for generating cloud imaged for Linux operating systems which employ kickstart files for automated installs.
The tool takes advantage of hard drive emulation enabled on most distribution ISO images, booting into Anaconda to perform an automated build with a kickstart file imbedded into the image.
For now it only supports AWS, but expect more providers in the future.
This tool is still in early development, but is being used. Please report issues. PRs welcome!
See the examples directory for configuration and kickstart examples.
To build a basic AMI for Rocky 9, make sure you have AWS credentials configured and run:
imogen -c examples/rocky-9.yaml --aws
If you need to probe the system during the build, you can use a %pre script and have it log to the console
%pre --log=/dev/tty
ls -l /sys/class/block
%endCheck the cloud-init logs. The growpart module doesn't support LVM, so you'll need to create your own logic and run it in bootcmd
