目录json 格式导出 namespace 信息修改 json 文件开启 proxy 服务调用接口删除 namespace
以下的 tool 为 Terminating 状态的 namespace,下面相关的一些操作记得将 tool 修改成自己的 namespace 名称
json 格式导出 namespace 信息
k get ns tool -o json > tool.json修改 json 文件
{ “apiVersion”: “v1”, “kind”: “Namespace”, “metadata”: { “annotations”: { “applicationCnName”: “tool”, “kubernetes.customized/bocloud_env_id”: “3”, “kubernetes.customized/bocloud_partition_id”: “172”, “kubernetes.customized/project_creator”: “7”, “kubernetes.customized/project_id”: “10”, “kubernetes.customized/tree_application_id”: “10” }, “creationTimestamp”: “2022-10-18T06:38:25Z”, “deletionTimestamp”: “2022-10-20T02:34:18Z”, “labels”: { “app”: “tool” }, “name”: “tool”, “resourceVersion”: “1011030”, “selfLink”: “/api/v1/namespaces/tool”, “uid”: “79793f2c-5290-4225-938b-8ce9e639a38c” }, “spec”: { “finalizers”: [ “kubernetes” ] }, “status”: { “conditions”: [ { “lastTransitionTime”: “2022-10-20T02:34:23Z”, “message”: “Discovery failed for some groups, 2 failing: unable to retrieve the complete list of server APIs: custom.metrics.k8s.io/v1beta1: the server is currently unable to handle the request, metrics.k8s.io/v1beta1: the server is currently unable to handle the request”, “reason”: “DiscoveryFailed”, “status”: “True”, “type”: “NamespaceDeletionDiscoveryFailure” }, { “lastTransitionTime”: “2022-10-20T02:34:23Z”, “message”: “All legacy kube types successfully parsed”, “reason”: “ParsedGroupVersions”, “status”: “False”, “type”: “NamespaceDeletionGroupVersionParsingFailure” }, { “lastTransitionTime”: “2022-10-20T02:34:23Z”, “message”: “All content successfully deleted, may be waiting on finalization”, “reason”: “ContentDeleted”, “status”: “False”, “type”: “NamespaceDeletionContentFailure” }, { “lastTransitionTime”: “2022-10-20T02:34:23Z”, “message”: “All content successfully removed”, “reason”: “ContentRemoved”, “status”: “False”, “type”: “NamespaceContentRemaining” }, { “lastTransitionTime”: “2022-10-20T02:34:23Z”, “message”: “All content-preserving finalizers finished”, “reason”: “ContentHasNoFinalizers”, “status”: “False”, “type”: “NamespaceFinalizersRemaining” } ], “phase”: “Terminating” } }将 spec 和 status 下面的内容清空,将 metadata 字段花括号结尾的逗号去掉,保留完整的 json 格式
以下是修改过后的样式 [ 提供参考的,用来和原始 json 做对比,好增加理解 ]
{ “apiVersion”: “v1”, “kind”: “Namespace”, “metadata”: { “annotations”: { “applicationCnName”: “tool”, “kubernetes.customized/bocloud_env_id”: “3”, “kubernetes.customized/bocloud_partition_id”: “172”, “kubernetes.customized/project_creator”: “7”, “kubernetes.customized/project_id”: “10”, “kubernetes.customized/tree_application_id”: “10” }, “creationTimestamp”: “2022-10-18T06:38:25Z”, “deletionTimestamp”: “2022-10-20T02:34:18Z”, “labels”: { “app”: “tool” }, “name”: “tool”, “resourceVersion”: “1011030”, “selfLink”: “/api/v1/namespaces/tool”, “uid”: “79793f2c-5290-4225-938b-8ce9e639a38c” } }开启 proxy 服务
这个时候要新打开一个终端,开启的 proxy 服务不是后台运行的,会占用一个终端
kubectl proxy开启后会返回如下的内容
Starting to serve on 127.0.0.1:8001调用接口删除 namespace
在另一个可以操作命令的终端,执行下面的 curl 命令
tool.json – 记得修改成自己的文件名称tool/finalize – 里面的 tool 修改成自己的 namespace 名称 curl -k -H “Content-Type: application/json” -X PUT –data-binary @tool.json http://127.0.0.1:8001/api/v1/namespaces/tool/finalize通过 kubectl 命令查看 namespace 是否还存在
