Parse byte array for yaml value - kubebuilder - json

Question

We are using kubebuilder to build our custom controller, the problem is we are not able to parse raw data as it comes empty when you apply the file.
I’ve created very minimal example which describe the issue.
apiVersion: mygroup.test.com/v1alpha1
kind: Rawtest
metadata:
name: rawtest-sample
spec:
system:
type: test
provider:
type: aws
infrastructureConfig:
kind: InfrastructureConfig
apiVersion: v1alpha1
networks:
vpc:
cidr: aaa
zones:
- name: abc
internal: 123
workers:
- name: myworker
machine:
type: "mt"
image:
name: name1
version: "2"
maximum: 2
minimum: 1
maxUnavailable: 0
volume:
type: a1
size: 20Gi
zones:
- zone1
In runtime I was able to get the the spec.system.type value=test and spec.system.provider.type value="aws", however I wasn’t able to get all the data under the infrastructureConfig: (line 10) any idea how can I overcome this ?
I’ve created this very simple project to demonstrate the issue ,
See the api/type folder, after getting the reconcile object (after apply the config/sample/ file ,you see that the infrastructureconfig and all related data are

Here is the code which is trying to read the raw value
https://github.com/JennyMet/kuberaw/blob/master/controllers/rawtest_controller.go#L57
&rawtest should contain all the data
please see the type

I need a way to make it work in the kubebuilder, as while I apply the file I dont get the values in debug ...

if something is missing please let me know.

I did the following
visit a site such as https://yaml.to-go.online/ convert the yaml to a go Struct
make a struct
t := AutoGenerated{}
I assume that the yaml data is loaded into memory as []byte
using "gopkg.in/yaml.v2", Unmarshall the yaml to the struct
err := yaml.Unmarshal([]byte(data), &t)
the infrastructureconfig field is available as t.Spec.System.Provider.InfrastructureConfig
