Building Images
The build prerequisites for using image-builder for
building hcloud images are managed by running:
make deps-hcloud
From the images/capi directory, run make build-hcloud-<OS> where <OS> is the desired operating system. The available choices are listed via make help. For example: Use make build-hcloud-ubuntu-2404 to build an Ubuntu 22.04 snapshot in hcloud.
Configuration
In addition to the configuration found in images/capi/packer/config, the hcloud
directory includes several JSON files that define the default configuration for
the different operating systems.
