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

This is a creation in Article, where the information may have evolved or changed. What is the difference between Apache's Mesos and Google's kubernetes? This article comes from a question on the StackOverflow, mainly discusses the difference between Mesos and kubernetes, I believe many of us also have the question of agreeing. Kubernetes's developer Craig answered the question, while Masi also made an overv

Kubernetes introduced Kubeadm from 1.3 to try to simplify its complex installation. But Kubeadm is still not stable, and I personally think Kubeadm instead of trouble, rather than directly with the script or other automated tools to install the neat. There are also alternatives to HA for KUBEADM configuration master, such as using highly available cluster software such as keepalived or Corosync. So in this document, I will still use the traditional wa

Come on , the first question:Rancher can quickly deploy kubernetes, but its use of the Gcr.io on the mirror cannot download what to do? With rancher you can quickly deploy kubernetes, but what images do we need to download? Rancher Support Private Image warehouse, how to set it? Problem Solving Ideas:Although the domestic network does not have direct access to the Gcr.io server, it has access to the hub.doc

First, kubernetes architectureKubernetes is the Google Open Source container cluster Management system, which provides application deployment, maintenance, extension mechanisms and other functions, using kubernetes can easily manage the cross-machine operation of containerized applications, the main functions are as follows:1) Use Docker for application wrapping (package), instantiation (instantiate), and r

This is a creation in Article, where the information may have evolved or changed. "Editor's words" This share is mainly zookeeper, Redis, Kafka, MongoDB and other applications containerized in the Kubernetes platform above practice. The problems of application in integration are analyzed from the aspects of computing, network and storage, and the application of some traditional applications in the process of container design is two times. This paper i

Recently, Bocloud Boyun novel formally received the CNCF and Linux Fund certified Kubernetes Service Provider qualification (KCSP), which proves Bocloud Boyun novel activities in the Kubernetes community (including active contribution code), business model supporting enterprise end users , as well as the presence of engineers on the site of the three sides have the corresponding technical strength.The KCSP

This is a creation in Article, where the information may have evolved or changed. All the places involved in storage are very prone to "pits", Kubernetes is no exception. First, the cause of the problem The problem began yesterday by upgrading the operation of a stateful service. The pod under the service is mounted with a persistent Volume provided with Ceph RBD. The pod is deployed with normal deployment and does not use the Petset in Alpha state. T

This article is connected to the previous article. Build the Kubernetes container in Bluemix.1. Create a clusterThe top left corner of the three horizontal, select the container, and then create the cluster.Note area, free version, give a name, create a cluster bar.Continue to be deployed, this may take 15-30 minutes, I am not sure, in order to give you a tutorial, I deleted my original.The following prerequisites install the tool according to the pro

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. Download image files and integrate them into the local warehouse

This is a creation in Article, where the information may have evolved or changed. Overview of related principles What is the first thing to say about the MLM? The MLM (Container network interface) is an operation container network specification, including method specification, parameter specification and so on.It only cares about the network connection of the container, allocates network resources when the container is created, and deletes the allocated resources when the container is deleted. B

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

Pod is the most basic deployment dispatch unit in Kubernetes, and it can contain container, which logically represents an instance of a certain application. For example, a Web site application is built from the front end, back end, and database, and these three components will run in their respective containers, so we can create a pod containing three container. This paper will do a simple analysis of the basic processing flow of
