seem to work ). The Kubernetes cluster depends on two third-party components: etcd and docker. The former provides status storage, and the two are used to manage containers. Clusters can also use distributed storage to provide storage space for containers. Displays the components of the current system: Kubernetes proxy nodes Kubelet and Kube-proxy run on the proxy node. They listen to Service node information to start containers and implement Kubern

First, kubernetes architectureKubernetes is the Google Open Source container cluster Management system, which provides application deployment, maintenance, extension mechanisms and other functions, using kubernetes can easily manage the cross-machine operation of containerized applications, the main functions are as follows:1) Use Docker for application wrapping (package), instantiation (instantiate), and run.2) Run and manage containers across machines in a clustered manner.3) solve the problem

There are several ways to install the Kubernetes cluster, the KUBEADM approach is described earlier, and the manual installation method is described in this article.The installation environment has 3 VMS on Azure:HKUBE01:10.0. 1.4 HKUBE02: 10.0. 1.5 Hbube03: 10.0. 1.6Where hkube01 is the master node, it will install Docker, ETCD, Kubernetes Master, flannel required components;HKUBE02 and hkube03 are worker nodes and will install Docker, kubernetes nod

context of microservices, both of these approaches require service discovery. In its simplest form, service discovery simply registers a running instance for one or more services. If that sounds like a DNS service to you, it does. The difference is that service discovery is used within the cluster to allow MicroServices to find each other, and DNS is generally more static and suitable for external routing, so the external party can request routing to your service. In addition, DNS services and

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's internal implementation mechanisms or are working on the development of kubernetes projects. Learning to learn the go language will help you to better understand this series of articles in some ways.In this installment, we'll start with a general overview of Kubernete

I. Introduction:Kubernetes is an open source container management tool, based on the Go language implementation, lightweight and portable applications, you can put kubernetes cluster on the Linux host deployment, management and expansion of the Docker container application on multiple hosts.Two. Architecture: 1. The kubernetes consists of the following components: Kubernetes Master Kubernetes nodes Etcd Kubernetes Network 2.
