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

Create a Kubernetes-dashboard In the previous article (SEE), deploy the Kubernetes-dashboard Based on the deployed kubernetes. It is an official user management Kubernets cluster visualization tool; deploying a dashboard is the same as deploying other applications in kubernets. Just create the Replication Controller and Service services required by the dashboard;

If you're an OPS engineer, you know that Docker is valued at more than $1 billion, and Docker is one of the most popular technology brands. Docker containers are known as the de facto standard for container runtimes, but Google's kubernetes is winning the choreography framework market. When using container technology, we often encounter the question, "will using Kubernetes hurt Docker?" ”Many people believe

This article describes the use of Node-exporter, Prometheus, Grafana to monitor the cluster in a k8s cluster.Its implementation principle is somewhat similar to elk, EFK combination. The Node-exporter component collects the metrics monitoring data on the node and pushes the data to Prometheus, Prometheus is responsible for storing the data, and grafana the data to the user in a graphical form on the Web page. Before you begin, it is necessary to understand what the next Prometheus is. Prometheu

In a cluster with TLS enabled, each time the cluster interacts with identity authentication, using Kubeconfig (i.e., certificates) and token two authentication methods is the simplest and most common authentication method.Take Kubectl as an example to introduce the configuration of Kubeconfig. Kubectl is just a go-written executable program that can be used by any node in the cluster as long as the appropriate Kubeconfig is configured for Kubectl. Kubectl Default is to find files with file names

Deploying Heketi and Glusterfs in Kubernetes[TOC]1. PrefaceIn Kubernetes, using the Glusterfs file system, the procedure is usually:Create brick--> Create volume--> Create pv--> create pvc-->pod mount PVCIf you are creating more than one PV, you need to manually repeat these interlocking steps, Heketi can resolve these duplication problems.Heketi is used to manage the life cycle of the glusterfs volume and

By default, Kubernetes has a certificate validity period of 1 years when initializing a cluster. Manually generating certificates can avoid this problem. Pull git code git clone https://github.com/fandaye/k8s-tls.git CD k8s-tls/2. Edit the configuration file ' Apiserver.json ' file in the Hosts section, add the corresponding Kubernetes master node hostname and IP address to ', ' number interv

Summary Project Background (XX Bank customer): The private cloud on the k8s to run like MySQL in the state of the database services, performance and latency are relatively sensitive, not like the web bias application of stateless delay performance almost acceptable. But the network performance and delay is poor based on overlay mode, and the network architecture is more complex. And banks need to be simple and controllable for IP network management. Sr-iov is based on hardware implementation of

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

OverviewCoredns is so notorious because it was introduced from kubernetes1.9 as the default DNS for Kubernetes internal service discovery. There is no doubt that Kubernetes is one of Coredns's backend, so we speak Coredns, starting with Kubernetes as the back end.Many of Coredns's features are mentioned on the web and are not covered here. A simple comparison of

Mesos and Kuberneteshttp://dockone.io/article/956 I firmly believe that their use will grow faster in the next year, so it is time to review the summary and prepare for 2016 years. I would like to discuss the current situation of Mesos and kubernetes and enumerate the strengths and weaknesses that will allow you to understand the concept of cluster manager.Mesos and KubernetesBefore I start, I'd like to take the time to roughly compare Mesos and

Colleagues who have studied kubernetes know that kubernetes if you need to enable TLS authentication, making a certificate is an essential step. However, many people encounter a lot of trouble in making certificates. Today is the main record of how I made my certificate during the deployment of Kubernetes. Throughout the process, the startup parameters for each c

Tags: WordPress MySQL KubernetesWordPress is the main platform for editing and publishing Web content. In this tutorial, I'll step through how to use kubernetes to build a high availability (HA) WordPress deployment.WordPress consists of two main components: a wordpress PHP server and a database for storing user information, posts, and website data. We need to make these two components in the entire application both highly available and fault tolerant
