使用kubernetes中，无法删除NameSpace怎么处理？

更新时间:2020-04-04 来源:黑马程序员浏览量:

在使用kubernetes过程中，我们经常会遇到无法删除NameSpace的情况，但是如果一一去删除NameSpace中资源比较麻烦。下面我们给大家介绍强制删除NameSpace的方法。推荐了解linux云计算+运维开发课程。

一、查看已存在的NameSpace

[root@master1 ~]# kubectl get ns

NAME STATUS AGE

default Active 56d

ingress-nginx Active 49d

istio-system Terminating 37d

kube-node-lease Active 56d

kube-public Active 56d

kube-system Active 56d

二、获取需要强制删除的NameSpace信息

[root@master1 ~]# kubectl get namespace istio-system -o json > istio-system.json

[root@master1 ~]# cat istio-system.json

{

"apiVersion": "v1",

"kind": "Namespace",

"metadata": {

"annotations": {

"kubectl.kubernetes.io/last-applied-configuration": "{\"apiVersion\":\"v1\",\"kind\":\"Namespace\",\"metadata\":{\"annotations\":{},\"labels\":{\"istio-injection\":\"disabled\",\"istio-operator-managed\":\"Reconcile\",\"operator.istio.io/component\":\"Base\",\"operator.istio.io/managed\":\"Reconcile\",\"operator.istio.io/version\":\"1.4.3\"},\"name\":\"istio-system\"}}\n"

"creationTimestamp": "2020-01-27T15:26:48Z",

"deletionTimestamp": "2020-02-15T01:17:05Z",

"labels": {

"istio-injection": "disabled",

"istio-operator-managed": "Reconcile",

"operator.istio.io/component": "Base",

"operator.istio.io/managed": "Reconcile",

"operator.istio.io/version": "1.4.3"

"name": "istio-system",

"resourceVersion": "6024170",

"selfLink": "/api/v1/namespaces/istio-system",

"uid": "d8bdc915-ee6f-43cd-ac37-5e353218095f"

"spec": {

"finalizers": [

"kubernetes"

]

"status": {

"conditions": [

{

"lastTransitionTime": "2020-02-15T01:17:10Z",

"message": "Discovery failed for some groups, 1 failing: unable to retrieve the complete list of server APIs: metrics.k8s.io/v1beta1: the server is currently unable to handle the request",

"reason": "DiscoveryFailed",

"status": "True",

"type": "NamespaceDeletionDiscoveryFailure"

{

"lastTransitionTime": "2020-02-15T01:17:13Z",

"message": "All legacy kube types successfully parsed",

"reason": "ParsedGroupVersions",

"status": "False",

"type": "NamespaceDeletionGroupVersionParsingFailure"

{

"lastTransitionTime": "2020-02-15T01:17:13Z",

"message": "All content successfully deleted, may be waiting on finalization",

"reason": "ContentDeleted",

"status": "False",

"type": "NamespaceDeletionContentFailure"

{

"lastTransitionTime": "2020-02-15T01:17:40Z",

"message": "All content successfully removed",

"reason": "ContentRemoved",

"status": "False",

"type": "NamespaceContentRemaining"

{

"lastTransitionTime": "2020-02-15T01:17:13Z",

"message": "All content-preserving finalizers finished",

"reason": "ContentHasNoFinalizers",

"status": "False",

"type": "NamespaceFinalizersRemaining"

}

"phase": "Terminating"

}

三、修改已获取的NameSpace信息文件

[root@master1 ~]# cat istio-system.json

{

"apiVersion": "v1",

"kind": "Namespace",

"metadata": {

"annotations": {

"creationTimestamp": "2020-01-27T15:26:48Z",

"deletionTimestamp": "2020-02-15T01:17:05Z",

"labels": {

"istio-injection": "disabled",

"istio-operator-managed": "Reconcile",

"operator.istio.io/component": "Base",

"operator.istio.io/managed": "Reconcile",

"operator.istio.io/version": "1.4.3"

"name": "istio-system",

"resourceVersion": "6024170",

"selfLink": "/api/v1/namespaces/istio-system",

"uid": "d8bdc915-ee6f-43cd-ac37-5e353218095f"

"spec": {

"status": {

"conditions": [

{

"lastTransitionTime": "2020-02-15T01:17:10Z",

"message": "Discovery failed for some groups, 1 failing: unable to retrieve the complete list of server APIs: metrics.k8s.io/v1beta1: the server is currently unable to handle the request",

"reason": "DiscoveryFailed",

"status": "True",

"type": "NamespaceDeletionDiscoveryFailure"

{

"lastTransitionTime": "2020-02-15T01:17:13Z",

"message": "All legacy kube types successfully parsed",

"reason": "ParsedGroupVersions",

"status": "False",

"type": "NamespaceDeletionGroupVersionParsingFailure"

{

"lastTransitionTime": "2020-02-15T01:17:13Z",

"message": "All content successfully deleted, may be waiting on finalization",

"reason": "ContentDeleted",

"status": "False",

"type": "NamespaceDeletionContentFailure"

{

"lastTransitionTime": "2020-02-15T01:17:40Z",

"message": "All content successfully removed",

"reason": "ContentRemoved",

"status": "False",

"type": "NamespaceContentRemaining"

{

"lastTransitionTime": "2020-02-15T01:17:13Z",

"message": "All content-preserving finalizers finished",

"reason": "ContentHasNoFinalizers",

"status": "False",

"type": "NamespaceFinalizersRemaining"

}

"phase": "Terminating"

}

四、运行kube-proxy

[root@master1 ~]# kubectl proxy

Starting to serve on 127.0.0.1:8001

五、通过API执行强制删除操作

[root@master1 ~]# curl -k -H "Content-Type: application/json" -X PUT --data-binary @istio-system.json http://127.0.0.1:8001/api/v1/namespaces/istio-system/finalize

六、强制删除确认

[root@master1 ~]# kubectl get ns

NAME STATUS AGE

default Active 56d

ingress-nginx Active 49d

kube-node-lease Active 56d

kube-public Active 56d

kube-system Active 56d
