78480241First, Background introduction 众所周知，由于国内网络原因，在搭建 Kubernetes 环境时，经常遇到必须的镜像找不到的情况。 到 DockerHub 捡垃圾毕竟不是个好办法，本文就教大家在 DockerHub 搭建自己的镜像仓库。 要求：有 GitHub 账号，有 DockerHub 账号，没有请注册。Ii. Basic Steps2.1 登陆 GitHub，创建代码仓库，比如：googlecontainer2.2 克隆代码（地址换成你的）#git Clone Https://github.com/SataQiu/googlecontainer.git2.3 Writing Dockerfile (take dashboard as an example)[Plain] View plain copy#cd Googlecontainer#mkdir Dashboard#cd Dashboard#vi

This is a creation in Article, where the information may have evolved or changed. Overview of related principles What is the first thing to say about the MLM? The MLM (Container network interface) is an operation container network specification, including method specification, parameter specification and so on.It only cares about the network connection of the container, allocates network resources when the container is created, and deletes the allocated resources when the container is deleted. B

Pod is the most basic deployment dispatch unit in Kubernetes, and it can contain container, which logically represents an instance of a certain application. For example, a Web site application is built from the front end, back end, and database, and these three components will run in their respective containers, so we can create a pod containing three container. This paper will do a simple analysis of the basic processing flow of

This article mainly introduces the kubernetes related commands, for the initial contact Kubernetes reference.Kubernetes through the kube-apiserv

This is a creation in Article, where the information may have evolved or changed. Node(also known minion as) runs docker container , and master is responsible for scheduling the management of these container . MasterRun the following services: API Server-nearly All the components on the master and nodes accomplish their respective tasks by making API calls. These is handled by the API Server running on the master. ETCD-

This is a creation in Article, where the information may have evolved or changed. This series of documentation describes kubernetes all the steps of using a binary deployment cluster, rather than kubeadm deploying the cluster using automated methods; During deployment, the startup parameters of each component are listed in detail, their meanings, and the problems they may encounter. Once the deployment is complete, you will understand the interaction

balancing, the subordinate node needs to report its status and resource status to the main control node, and finally carry out the business.Similarly, Kubernetes does provide the basic functions of the principal and subordinate roles described above, and identifies specific components to divide and conquer specific functions:On master, ETCD load persistent storage, used to store various types of resources

Controller manager and scheduler. To achieve this reliably, we are want to having one actor modifying state at a time, but we want replicated instances of th ESE actors, in case a machine dies. To achieve this, we is going to use a lease-lock with the API to perform master election. We'll use --leader-elect the flags for each scheduler and Controller-manager, using a lease in the API would ensure that's only 1 ins Tance of the Scheduler and Controller-manager is running at once.That is, Control

Kubernetes is a master-slave structure, it mainly implements the Docker of the dispatch, the following detailed introduction of my understanding of the Kubernetes architecture: Master node : API Server: Provides the API interface of cluster management, it becomes the central hub of data interaction and communication between each function module in the cluster, and has the complete cluster security mechani
