我在 Kubernetes 中的自定义资源定义 URL 是什么

Question

我正在尝试在 Kubernetes 中访问我的自定义资源定义端点，但找不到 Kubernetes 如何在 Kubernetes API 中公开我的自定义资源定义的确切示例。如果我用这个点击自定义服务 API：

https://localhost:6443/apis/apiextensions.k8s.io/v1beta1/customresourcedefinitions

我得到这个回复

"items": [
{
"metadata": {
"name": "accounts.stable.ibm.com",
"selfLink": "/apis/apiextensions.k8s.io/v1beta1/customresourcedefinitions/accounts.stable.ibm.com",

}

这让我相信我已经正确创建了自定义资源帐户。有很多例子似乎不太正确，我在 Kubernetes REST API 中找不到我的资源。我可以与kubectl中的自定义资源一起使用，但我需要使用 RESTful API 公开它。

https://localhost:6443/apis/stable.example.com/v1/namespaces/default/accounts

返回

404 page not found

其中：

https://localhost:6443/apis/apiextensions.k8s.io/v1beta1/apis/stable.ibm.com/namespaces/default/accounts

返回

{
"kind": "Status",
"apiVersion": "v1",
"metadata": {},
"status": "Failure",
"message": "the server could not find the requested resource",
"reason": "NotFound",
"details": {},
"code": 404
}

我看过 https://docs.okd.io/latest/admin_guide/custom_resource_definitions.html 和 https://kubernetes.io/docs/tasks/access-kubernetes-api/custom-resources/custom-resource-definitions/

确切的网址将不胜感激。

这是一种相当不错的方法，可以在一些顶级调试级别上检索执行kubectl get命令的 K8s REST API 资源，如评论中提到的@Suresh Vishnoi：

kubectl get <api-resource> -v=8

显然，最终由 Kumar Gupta @Amit检查，根据您的 CRD json 输出访问自定义资源的正确 URL 如下：

https://<API_server>:port/apis/stable.ibm.com/v1/namespaces/default/accounts

根据身份验证方法，您可以选择：X509 客户端证书、静态令牌文件、持有者令牌或 HTTP API 代理，以便针对 Kubernetes API 对用户请求进行身份验证。
