k8s的namespace一直Terminating的完美解决方案

k8s的namespace一直Terminating的完美解决方案

在k8s集群中进行测试删除namespace是经常的事件，而为了方便操作，一般都是直接对整个名称空间进行删除操作。
相信道友们在进行此步操作的时候，会遇到要删除的namespace一直处于Terminating。下面我将给出一个完美的解决方案，

测试demo

创建demo namespace# kubectl create ns testnamespace/test created删除demo namespace# kubectl delete ns testnamespace "test" deleted一直处于deleted不见exit查看状态 可见test namespace 处于Terminating # kubectl get ns -wNAME    STATUS  AGEtest    Terminating 18s

下面给出一种完美的解决方案：调用接口删除

开启一个代理终端# kubectl proxyStarting to serve on 127.0.0.1:8001再开启一个操作终端将test namespace的配置文件输出保存# kubectl get ns test -o json > test.json删除spec及status部分的内容还有metadata字段后的","号，切记！剩下内容大致如下{ "apiVersion": "v1", "kind": "Namespace", "metadata": {  "annotations": {   "cattle.io/status": "{\"Conditions\":[{\"Type\":\"ResourceQuotaInit\",\"Status\":\"True\",\"Message\":\"\",\"LastUpdateTime\":\"2020-10-09T07:12:17Z\"},{\"Type\":\"InitialRolesPopulated\",\"Status\":\"True\",\"Message\":\"\",\"LastUpdateTime\":\"2020-10-09T07:12:18Z\"}]}",   "lifecycle.cattle.io/create.namespace-auth": "true"  },  "creationTimestamp": "2020-10-09T07:12:16Z",  "deletionTimestamp": "2020-10-09T07:12:22Z",  "name": "test",  "resourceVersion": "471648079",  "selfLink": "/api/v1/namespaces/test",  "uid": "862d311e-d87a-48c2-bc48-332a4db9dbdb" }}调接口删除# curl -k -H "Content-Type: application/json" -X PUT --data-binary @test.json "kind": "Namespace", "apiVersion": "v1", "metadata": { "name": "test", "selfLink": "/api/v1/namespaces/test/finalize", "uid": "862d311e-d87a-48c2-bc48-332a4db9dbdb", "resourceVersion": "471648079", "creationTimestamp": "2020-10-09T07:12:16Z", "deletionTimestamp": "2020-10-09T07:12:22Z", "annotations": {  "cattle.io/status": "{\"Conditions\":[{\"Type\":\"ResourceQuotaInit\",\"Status\":\"True\",\"Message\":\"\",\"LastUpdateTime\":\"2020-10-09T07:12:17Z\"},{\"Type\":\"InitialRolesPopulated\",\"Status\":\"True\",\"Message\":\"\",\"LastUpdateTime\":\"2020-10-09T07:12:18Z\"}]}",  "lifecycle.cattle.io/create.namespace-auth": "true" } }, "spec": { }, "status": { "phase": "Terminating", "conditions": [  {  "type": "NamespaceDeletionDiscoveryFailure",  "status": "True",  "lastTransitionTime": "2020-10-09T07:12:27Z",  "reason": "DiscoveryFailed",  "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"  },  {  "type": "NamespaceDeletionGroupVersionParsingFailure",  "status": "False",  "lastTransitionTime": "2020-10-09T07:12:28Z",  "reason": "ParsedGroupVersions",  "message": "All legacy kube types successfully parsed"  },  {  "type": "NamespaceDeletionContentFailure",  "status": "False",  "lastTransitionTime": "2020-10-09T07:12:28Z",  "reason": "ContentDeleted",  "message": "All content successfully deleted"  } ] }}

查看结果

1、delete 状态终止kubectl delete ns testnamespace "test" deleted2、Terminating状态终止kubectl get ns -wtest    Terminating 18stest    Terminating 17m

名称空间被删除掉
