K8S命名空间一直是Terminating的完美解决方案。测试和删除K8S集群中的名称空间是一个经常发生的事件。为了方便操作，通常直接删除整个命名空间。我相信，当朋友们做这一步时，他们会遇到要删除的命名空间总是在Terminating中。接下来，我将给出一个完美的解决方案来测试demo，以创建demonamespace#kubectlcreatestnames
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 test
namespace/test created
删除demo namespace
# kubectl delete ns test
namespace "test" deleted
一直处于deleted不见exit
查看状态 可见test namespace 处于Terminating
# kubectl get ns -w
NAME STATUS AGE
test 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 proxy
Starting 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 http://127.0.0.1:8001/api/v1/namespaces/test/finalize
{
"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 test
namespace "test" deleted
2、Terminating状态终止
kubectl get ns -w
test Terminating 18s
test Terminating 17m
名称空间被删除掉
