Docker Network BasicsSince Kubernetes is based on the Docker container as the carrier of the application release, the network characteristics of Docker also determine that kubernetes in building a container interoperability network must solve the problem of Docker's own network.Network namespacesTo support multiple instances of the network protocol stack, Linux introduces a network namespace in the network

-speed storage to store a large number of fragmented files. What the user needs to do is submit the resource request to the cloud platform and then fetch and consume the storage resource without worrying about which disk of the storage server The underlying store is from. to meet the storage needs of container users in the cloud environment. Kubernetes provides the concept of persistent volumes (PERSISTENTVOLUME,PV) and persistent volume requests (PE

Kubernetes can connect pods on different node nodes in the cluster, and by default, each pod is accessible to each other. However, in some scenarios, different pods should not be interoperable, and access control is required at this time. So how does it work?Brief introduction?? Kubernetes provides Networkpolicy feature, which supports network access control by namespace and by pod level. It uses the label

Introduction and practice of pod in kubernetes The concept of podDetailed pod explanation can refer to k8s official website, the concept of pod mainly has the following points:(1) Pod is the smallest and simplest unit that you can create and deploy in Kubernetes. A pod represents a process that runs in a cluster;(2) How to use pod in kubrenetes cluster;(3) How to manage multiple containers in pod Unde

[TOC]Introduction to Kubernetes DispatchingIn addition to having the Kubernetes cluster scheduler automatically select a node for the pod resource (the default schedule is that the resources are sufficient and the load is as average as possible), there are situations where we want to have more control over how the pod should be dispatched. For example, some of the machines in the cluster are better configur

Official Document: HTTPS://WWW.KUBERNETES.ORG.CN/DOC-11The Kubernetes cluster contains the node agent Kubelet and master components (APIs, scheduler, etc), all based on a distributed storage system. The following diagram is an architectural diagram of the kubernetes.Kubernetes nodeIn this system architecture diagram, we divide the service into services running on the work nodes and the services that make up the cluster-level dashboard.The

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
