How can i export openshift native resource defination to yaml file, like Project/DeploymentConfig/BuildConfig

[chestarss]

I want export openshift resource defination like CRD YAML file, which import to k8s api server.

from openshift:
oc get crd project.openshift.io > project_crd.yaml

to k8s
kubectl apply -f project_crd.yaml

why i want do this?
Because I use karmada component for mulit cluster management, my member clusters is openshift. karmada control panel only support kube-apiserver, which not have Project resource.

There is no CRDs for the internal OpenShift APIServer types. The CR types are provided by the API aggregation step, making the OpenShift-API a required component for providing these endpoints. There are mutations and validations that are performed within the OpenShift API that will also not run if you are able to export the types as CRDs for use with KubeAPI alone. I don't think it's possible to get the same functionality out of the box by exporting the types as CRDs.

Or do you just want a type called Project, with no desire for the additional functionality such as ServiceAccount creation and isolation?

yes, i just want type define not implement . I use it for karmada-apiserver which base kube-apiserver for multi-cluster management. karmada-apiserver not support proxy openshift only types

Hi MichaelWasher,

I have same question like how do we export native CRDs like deploymentConfig..etc. My use case is "we are using CDK8s for our manifest generating and it is very easy to import existing CRD into libraries but didn't find a way to get this openshift native API CRDs "deploymentconfig/route/..etc".
