kubectl CRD 캐스케이드 삭제

삭제대상 CRD 목록 조회

$ kubectl get crds -oname | grep cluster.x-k8s.io | sed 's|.*/||'
addonproviders.operator.cluster.x-k8s.io
bootstrapproviders.operator.cluster.x-k8s.io
clusterclasses.cluster.x-k8s.io
...
machinepools.cluster.x-k8s.io
machines.cluster.x-k8s.io
machinesets.cluster.x-k8s.io

삭제대상 CRD 인스턴스 목록 조회

$ kubectl get crds -oname | grep cluster.x-k8s.io | sed 's|^.*/||' | xargs -n1 kubectl get -A -o custom-columns=":metadata.namespace,:kind,:metadata.name" | xargs -n3 echo
capi-kubeadm-bootstrap-system BootstrapProvider kubeadm
capi-kubeadm-control-plane-system ControlPlaneProvider kubeadm
capi-system CoreProvider cluster-api
docker-infrastructure-system InfrastructureProvider docker

삭제대상 CRD 인스턴스 목록 조회 + 삭제 명령어 생성

$ kubectl get crds -oname | grep cluster.x-k8s.io | sed 's|^.*/||' | xargs -n1 kubectl get -A -o custom-columns=":metadata.namespace,:kind,:metadata.name" | xargs -n3 echo kubectl delete -n
kubectl delete -n capi-kubeadm-bootstrap-system BootstrapProvider kubeadm
kubectl delete -n capi-kubeadm-control-plane-system ControlPlaneProvider kubeadm
kubectl delete -n capi-system CoreProvider cluster-api
kubectl delete -n docker-infrastructure-system InfrastructureProvider docker

CRD 인스턴스 삭제 (앞에서 생성된 삭제 명령어 실행)

$ kubectl delete -n capi-kubeadm-bootstrap-system BootstrapProvider kubeadm
bootstrapprovider.operator.cluster.x-k8s.io "kubeadm" deleted
$ kubectl delete -n capi-kubeadm-control-plane-system ControlPlaneProvider kubeadm

$ kubectl delete -n docker-infrastructure-system InfrastructureProvider docker
