Kubernetes Dashboard is a generic web-based UI for Kubernetes clusters. It allows users to manage and troubleshoot applications running in a cluster, and to manage the cluster itself.Deploying DashboardProject GitHub AddressOfficial documentation ReferenceGet Yaml filecurl -O https://raw.githubusercontent.com/kubernetes/dashboard/master/src/deploy/recommended/
1. Preface
Together we'll ensure that Kubernetes are a strong and open container management framework for all application and in any Environment, whether in a private, public or hybrid cloud.

Kubernetes ArchitectureThe overall architecture of the kubernetes is as follows:Master is the main control node, which runs Apiserver,scheduler,controller-manager and other components. Minion is the equivalent of a working node, which runs Kubelet,proxy,cadvisor and the most important Docker components. Here's how to actually deploy this cluster management tool.EnvironmentYy1 10.193.6.35Yy2 10.193.6.36Yy1 a

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:
Analysis of Kubernetes Application Deployment model (Principles)
Abstract: this series of articles focus on actual deployment and give you a quick grasp of Kubernetes. This article describes the principles and concepts that need to be understood before deployment, including the Kubernetes component structure, functions of each component role, and
From Mesos to KubernetesThe previous scheduling framework was based on Mesos self-research. The language used is Python. Run for about two years, and has been relatively stable. But as the business grows, the problems of the existing framework are gradually exposed.
Scheduling speed encountered bottlenecks, affecting the deployment of large business speed.
There is no good support for stateful services.
There are two solutions to this problem, one for improved refactoring of ex

Use Kubernetes step by stepWhy Docker and Kubernetes?
Containers allow us to build, publish, and run distributed applications. They free applications from machine restrictions and allow us to create a complex application in a certain way.
Writing applications using containers can bring development and QA closer to the production environment (if you try to do so ). By doing so, you can publish changes faster
First of all, to everyone popular science under the kubernetes choice of the network interface, a brief introduction of the network implementation of the background.The container network Interface is a set of container networks definition specification, including method specification, parameter specification, response specification and so on. The MLM only requires that network resources be freed when the container is created, when the container is all
Once again, the architecture is clear: three virtual machine CentOS 7.4 systems, Docker 17, IP 10.10.90.105 to 107, 105-bit master, and the next master-related components installed on this machine.The ETCD cluster is 3 units, which are reused for each of the 3 virtual machines.As the core of k8s, the master node consists of three components, namely:Three components:kube-apiserverkube-schedulerkube-controller-managerThis three components are closely linked1.

Node runs Kubernetes's kubelet, Kube-proxy service processes, which are responsible for pod creation, startup, monitoring, restart, destruction, and load balancing for software patterns. The information that node contains:
