kubernetes 에서 namespace를 삭제를 하게 되면 정상적으로 진행이 되지 않는 경우
아래와 같이 Terminating 상태로 표시가 된다
|
1 2 3 4 5 6 7 8 |
[root@k8smaster ~]# kubectl get ns NAME STATUS AGE default Active 4d3h kube-node-lease Active 4d3h kube-public Active 4d3h kube-system Active 4d3h kubernetes-dashboard Terminating 59m orange Active 4d1h |
그럼 정상적으로 삭제를 하기 위해서 상태를 확인한다

json 파일로 추출

[root@k8smaster ~]# kubectl get namespaces kubernetes-dashboard -o json > kubernetes-dashboard.json |
kubernetes 내용을 삭제
|
1 |
[root@k8smaster ~]# sed -i '/"kubernetes"/d' kubernetes-dashboard.json |
kubectl proxy 백그라운드 실행
|
1 |
[root@k8smaster ~]# kubectl proxy & |
curl 호출하여 정상진행
|
1 |
[root@k8smaster ~]# curl -k -H "Content-Type: application/json" -X PUT --data-binary @kubernetes-dashboard.json http://127.0.0.1:8001/api/v1/namespaces/kubernetes-dashboard/finalize |

여기에서 수정할 항목은 @ 부분에 namespace 이름
finalize 부분 앞 부분에 namespace 이름
namespace 상태 확인

[root@k8smaster ~]#kubectl get ns NAME STATUS AGE default Active 4d3h kube-node-lease Active 4d3h kube-public Active 4d3h kube-system Active 4d3h orange Active 4d1h |
정상적으로 삭제된것을 확인 할 수 있다
