Based on https://github.com/openshift-evangelists/crd-code-generation
First register the custom resource definition:
kubectl apply -f artifacts/network-crd.yaml
For old kubernetes version (<1.16), please use artifacts/networks-crd-v1beta1.yaml:
kubectl apply -f artifacts/networks-crd-v1beta1.yaml
Then add an example of the NetworkAttachmentDefinition kind:
kubectl apply -f artifacts/my-network.yaml
Finally build and run the example:
go build
./example -kubeconfig ~/.kube/config
