Support different sources of ignition #135

Open SchwarzM opened 2 months ago

SchwarzM commented 2 months ago

Summary

The ignition is currently one big file which holds several distinct parts of config at least:

I would want to expose these parts towards the different teams that need to provide input in a clean API.

Basic example

As a gardener operator i only write the ignition which adds the node to the cluster. As a network operator i only write the ignition which enables the node to interact with the fabric. As a ceph operator i can write an ignition which configures OS kernel settings towards the ceph use case. As a kvm operator i can write an ignition which configures OS kernel settings towards the hypervisor case.

Motivation

We do not need to manage a huge ignition which can hold even conflicting information from different sources.
