I. Introduction ofKubernetesKubernetes is Google open source container cluster management system, based on Docker to build a container scheduling service, providing resource scheduling, balanced disaster recovery, service registration, dynamic expansion capacity and other functional suites, using Kubernetes can easily manage the cross-machine operation of containerized applications. and

Configure the dashboard service for a Kubernetes Cluster This article describes how to create and use kube-ui (also called dashboard) based on the previous article. This is essentially an api interface for connecting webui to the master. It obtains information about the k8s cluster through the api and then displays it on the web, which is more friendly to users,

Service discovery mechanism Kubernetes provides two ways to discover the service:1. Environment Variables When the pod is running, Kubernetes writes the information for the service that existed before This method requires that the pod must be started after the service. The pod that was started before the service will not have an environment variable for that service. There is no such limit in the way
