Outline: ? How to discover services in Kubernetes ? How to discover the services provided by pod ? How to use service discovery Services ? How to use the Kube-dns discovery service ? Kube-dns principle ? Composition ? Domain name format ? Configuration Note: this share is based on the Kubernetes 1.2 version!Let's start with a simple example.1.How to discover service

images through projects. Kubernetes in the namespace to isolate resources, in an enterprise-level scenario, the combination of the two can effectively manage and access control of the mirrored resources used by kubernetes, enhancing the security of the image. Especially in multi-tenancy scenarios, the management and access control of multi-tenant mirrored resources can be achieved through a combination of

I. When deploying the Kubernetes cluster, we used Acs-engine to generate 3 JSON files and some certificate files, as follows: Apimodel.json-Cluster configuration file Azuredeploy.json-Core Arm (Azure Resource Model) template for deploying k8s clusters Azuredeploy.parameters.json-Deployment parameters file, where parameters can be customized Certificate and Access config Files-kubernetes

There are two requirements for stateful cluster services: one is storage requirements and the other is cluster requirements.For storage requirements, the Kubernetes solution is: Volume, persistent Volume. For PV, in addition to manually creating a PV pool, the storage system can be automatically created by storage class.For cluster requirements, the Kubernetes solution is pet Set. The Pet Set also initializ

To succeed in today's fast-paced development environment,Leveraging container technology and DEVOPS practicesIt is important to build and continuously deliver microservices.As a Java developer,As you integrate the latest tools and development methodologies,You need to take advantage of some of the powerful features of the Java language.Today, we're going to learn how to deploy Java-based microservices applications to Kubernetes clusters using Micropro

In a production environment kubernetes if you provide only HTTP or HTTPS services, you can use seven-tier load balancing software such as nginx-ingress or Traefik. Of course, you can also expose HTTP or TCP services in a nodeport way. If you do not want to directly use the port number exposed by Nodeport, and the server is running on the Ali Cloud, you can expose the TCP service or Controller service externally using the

Objective in the Kubernetes system, Scheduler is the only one in the plugin form of the module, this pluggable design to facilitate user-defined scheduling algorithm, so the source path for the plugin directory of CMD and pkg/scheduler Scheduler is responsible for arranging the pod to the specific node, monitoring the Pods through the interface provided by API Server, acquiring the pod to be scheduled, ranking each node nodes according to a series

Kubernetes Important Concept UnderstandingKubernetes is currently the most mainstream container orchestration tool, the next generation of distributed architecture of the king. 2018 Kubernetes The first version 1.10 has been released. Here's a look at some of the basic concepts of kubernetes.The kubernetes divides the machines in the cluster into master nodes and

Author: Peng Jingtian The node nodes of Kubernetes are composed of Kubelet, Kube-proxy, flannel, dockerd four components, this paper mainly analyzes the functions and principles of kube-proxy components. Pod is the smallest unit of resource allocation in kubernetes and the smallest entity to perform tasks. Each pod has a separate IP on the flannel overlay network. Pod Communication in node nodes is impleme

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

Deploy Kubernetes-dashboard on the basis of the deployment of Kubernetes, which is the official Kubernets cluster Visualizer for user management, and the deployment dashboard is actually the same as deploying other applications in Kubernets, Create dashboard required replication Controller, service services can be;Note that the overlay network of Kubernets is working properly, each node has started flannel,

Kubernetes can automatically run multiple copies of Odoo services, so it 's very well suited to make a highly available Odoo deployment, in this case,Odoo The service runs in the kubernetes cluster, while the PostgreSQL database runs in another Cluster host host Network on the other hostInstall kubernetes Cluster, there are many ways, as of now, the easiest is

Master Node component kube-apiserver 用于暴露kubernetes API，不管是kubectl 还是HTTP 调用来操作kubernets 集群各种资源，都是通过kube-apiserver 提供的接口进行操作的，Node 节点与Master之间的通信也是主要依赖于kube-apiserver，例如pod调度: kube-scheduler 将调度结果写入etcd，kubelet 监听etcd 获取到调度任务。 ETCD 一款用于共享配置和服务发现的高效KV存储系统，具有分布式、强一致性等特点，在kubernetes 环境中主要用于存储所有需要持久化的数据 kube-controller-manager 管理负责整个kubernetes的管理工作，保障集群中各种资源处于期望
