Brief description:This article covers 3 Ubuntu machines, 1 Rke deployment Machines (192.168.3.161), 2 kubernetes cluster machines (3.162 and 3.163).On the Windows machine, download the rke_linux-amd64 from GitHub, rename it to Rke, edit the cluster.yml cluster deployment file, and upload the file to the 3.161 machine using the PSCP command provided by Putty. On the 3.161 machine, execute the rke command to deploy the cluster to the 3.162 and 3.163 mac

Kubernetes using NFS as a shared storageKubernetes managed containers are encapsulated, and sometimes we need to put logs from the container running locally or shared storage to prevent the container from going down, and the logs can also analyze the problem. Kubernetes's shared storage scheme is currently more prevalent in three, namely: Nfs,glusterfs and Ceph.Previously wrote an article kubernetes use Glu

kubernetes clinet-go Development (I.) Kubernetes currently provides two ways to create the required pod,service,replicationcontroller, one is through Kubectl create-f, a restful interface via HTTP, because of the work item's reason, Need to be customized according to the actual business needs of the development of K8s API, I used the library is the official, code base address: Https://github.com/

Service on the line to the top of the live pressure, carry the test, or to be said or we do things brother, remember this scene above? The old method is a service cluster deployment, but there is always a limit, before with Ali when they have a flexible calculation can be set by the CPU's threshold to dynamically expand and shrink computing capacity, at that time the feeling is very strong, at least at that time our conventional approach is difficult to do, Did not expect to have

kubernetes Introduction Kubernetes is a container cluster management system that Google Open-source in June 2014, using the Go language development, Kubernetes also called k8s. K8s is a Borg container cluster management system inside Google, Borg has been operating on Google's mass production for 10 years. K8s is mainly used for automated deployment, expansion

[TOC]Introduction to Rolling UpdatesWhen a service in a kubernetes cluster needs to be upgraded, it is a traditional practice to go offline with the service that is being updated, to update the version and configuration after the business is stopped, and then to restart and provide the service. If the business cluster is large, this work becomes a challenge, and all stops first, and the gradual escalation will result in the service being unavailable f

"Editor's words" The Kubernetes Scheduler dispatches the pod to the work node according to a specific algorithm and strategy. By default, the Kubernetes scheduler can meet most of the requirements, such as scheduling pods to run on resource-rich nodes, or scheduling pod dispersal to different nodes to make cluster nodes resource balanced. However, in some special scenarios, the default scheduling algorithm

1. Foreword In the last article "Kubernetes Scheduler Module Analysis", the Scheduler scheduling process and the main algorithm are analyzed. From the overall grasp of the scheduler scheduling mechanism, today want to continue to analyze the more detailed content. 2. Summary Today, we mainly analyze the caching mechanism of scheduler, Extender extension mechanism and tainttoleration mechanism. These three aspects, although not so macroscopic, but for
