Gateway API is a family of API kinds that provide dynamic infrastructure provisioning and advanced traffic routing.

This command initializes a new Kubernetes node and joins it to the existing cluster. Run this on any machine you wish to join an existing cluster Synopsis When joining a kubeadm initialized cluster, we need to establish bidirectional trust. This is split into discovery (having the Node trust the Kubernetes Control Plane) and TLS bootstrap (having the Kubernetes Control Plane trust the Node). There are 2 main schemes for discovery.

The status of a node in Kubernetes is a critical aspect of managing a Kubernetes cluster. In this article, we'll cover the basics of monitoring and maintaining node status to ensure a healthy and stable cluster. Node status fields A Node's status contains the following information: Addresses Conditions Capacity and Allocatable Info You can use kubectl to view a Node's status and other details: kubectl describe node <insert-node-name-here> Each section of the output is described below.

Synopsis Approve a certificate signing request. kubectl certificate approve allows a cluster admin to approve a certificate signing request (CSR). This action tells a certificate signing controller to issue a certificate to the requester with the attributes requested in the CSR. SECURITY NOTICE: Depending on the requested attributes, the issued certificate can potentially grant a requester access to cluster resources or to authenticate as a requested identity. Before approving a CSR, ensure you understand what the signed certificate can do.

kubeadm reset phase enables you to invoke atomic steps of the node reset process. Hence, you can let kubeadm do some of the work and you can fill in the gaps if you wish to apply customization. kubeadm reset phase is consistent with the kubeadm reset workflow, and behind the scene both use the same code. kubeadm reset phase phase Use this command to invoke single phase of the "reset" workflow
