Kubernetes API Server FeaturesThe core function of Kubernete API server is to provide an HTTP rest interface for kubernetes, deleting, changing, checking, and watch for various resource objects (such as Node,pod,service, etc.).The

Welcome to an in-depth study of the Kubernetes API Server series, in this series of articles we will delve into the implementation of Kubernetes API server. This series of articles can help you if you are interested in Kubernetes'

In the first two parts of this series we describe the overall process of API server and how the API objects are stored in ETCD. In this article we will explore how to extend the API resources.In the beginning, the only way to extend the API resources is to extend the relevan

, such as local, you can use the same kube-config as Kubectl to configure the clients. If you're on the cloud, like Gke, you'll need an import Auth Plugin. The Clientset is generated with Client-gen. If you open pkg/api/v1/tyeps.go, there is a line of comments on the pod definition, called "+genclient=true", which means that you need to generate a client for this type, and if you want to do your own API

package dependenciesKubernetes is a platformKubernetes has a lot of popular places. Users like its rich functionality, stability, and performance. For contributors, the Kubernetes open source community is not only large, but also easy to get started and quick to respond to. What really makes kubernetes attractive to third-party developers is its extensibility. The project provides a number of ways to add

The browser requests the front-end server static resources, HTML, CSS and so on, The browser then makes an AJAX request to the API server, resulting in cross-domain issues. The plan I'm currently thinking of,First, the front and back resources are placed under the same domain name, but the feeling is not too reasonable.The second is to use the reverse proxy, but
