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

Run the MongoDB microservice on Docker and KubernetesGuideDocker is an open-source application container engine that allows developers to package their applications and dependencies to a portable container and then publish them to any popular Linux machine, you can also achieve virtualization. Containers fully use the sandbox mechanism and do not have any interfaces between them. This article describes how to use Docker and Kubernetes to build a set

Kubernetes Cluster Deployment DNS ServiceIn Kubernetes each service will be assigned a virtual IP, each service under normal circumstances will not change for a long time, this is relative to the pod of the indefinite IP, the use of the cluster app is relatively stable.But the service's information injected into the pod is currently using an environment variable, and relies heavily on pod (RC) and service c

Welcome to an in-depth study of the Kubernetes API Server series, in this series of articles we will delve into the implementation of Kubernetes API server. This series of articles can help you if you are interested in Kubernetes's internal implementation mechanisms or are working on the development of kubernetes projects. Learning to learn the go language will h

This article introduces the use of Docker and kubernetes to build a set of MONGODB services with redundant backup sets, from the container to the CI and CD-initiated changes, discussed the container technology to MONGODB challenges and opportunities, and then how to deploy a stable set of MONGODB services , very dry.IntroducedWant to try to run MongoDB on your laptop? Want to execute a simple command and then have a lightweight, self-organizing sandbo

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.

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

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, it is not very useful. 1.
