Introduction of TraefikTraefik is a front-end load balancer with good support for orchestration tools such as MicroServices architecture, especially

Helm IntroductionDeploying container cloud Applications (container or microservices orchestration) in Kubernetes is a challenging task, Helm is to simplify the installation of a client tool for deploying container cloud applications in Kubernetes. Helm enables developers to define, install, and upgrade container cloud applications in Kubernetes. At the same time,

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

Kubernetes cluster configuration notes This article describes how to configure a Kubernetes cluster. A kubernetes cluster consists of a master node and a slave node. Run the following services on the Master node:Etcd (the etcd service can also be run independently, not necessarily on the Master node)Kube-apiserverKube-controller-managerKube-schedulerKubeletKube-p

-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

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

Kubernetes is Google 's Open source container cluster management system. It is built on Docker technology and provides a whole set of functions, such as resource scheduling, deployment operation, service discovery, expansion and contraction capacity, for containerized applications, which can be regarded as Mini-paas platform based on container technology. The purpose of this article is to comb the architecture, concepts, and basic workflows of

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

Summary: Kubernetes is Google open source container cluster management system, built on Docker, for containerized applications to provide resource scheduling, deployment operations, service discovery, capacity expansion and other functions. Pods are the smallest deployment units that are created, dispatched, and managed, and this article describes the communication and scheduling between these pods in detailOverviewThe Pods in

containers, making deployment and management more flexible. 　　　　　　 　　　　　　 A pod can contain a container or multiple related containers. 2) Replication ControllerThe Replication Controller manages a copy of the pod to ensure that a specified number of pod copies exist in the cluster. If the number of replicas in the cluster is greater than the specified number, the number of extra containers that are outside the specified number is stopped, and conversely, containers with fewer than a specified

Hi,everybody, I came back, before the installation to flannel, the article has not been updated, even a lot of small partners to add QQ asked whether to continue to update,Here is the reason, I was in the deployment of 1.91node when there are a variety of problems, resulting in node startup Oh, master always do not see, the problem is probably1, Virtual machine time synchronization inconsistency problem, causing ETCD to create a resource is unsuccessful2, node nodes can not automatically create
