Kubernetes 1.5 installation and cluster environment deploymentArticle reprinted from: http://www.cnblogs.com/tynia/p/k8s-cluster.htmlBrief introduction:Docker: An open-source application container engine that can create a lightweight, portable, self-sufficient container for your application.Kubernetes: The Docker container Cluster Management system, which is open source by Google, provides the functions of resource scheduling, deployment operation, se

I. Introduction of COREDNSKubernetes includes the DNS server Kube-dns for service discovery. The DNS server leverages Skydns's libraries to provide DNS requests for kubernetes pods and services. SkyDNS2 's author, Miek Gieben, created a new DNS server, Coredns, which was built with a more modular, extensible framework. Infoblox has partnered with Miek to use this DNS server as a substitute for kube-dns.COREDNS leverages the server framework developed

first introduce what k8s is: (Quote from k8s Chinese community)Kubernetes is a container cluster management system, it is an open source platform, can realize the automatic deployment of container cluster, auto-scaling capacity, maintenance and other functions. Kubernetes you can: Quick Deploy app Rapid extension Application Seamless docking of new application features

This article will be based on the previous article on the configuration of the DNS service in the Kubernetes cluster environment, in the k8s cluster, pod life cycle is short, pod restart IP address will change, for the application this is unacceptable, in order to solve this problem, The k8s cluster cleverly introduces the DNS service to realize the discovery of the service, in which DNS requires a total of 4 components in the k8s cluster, each of whi

Kubernetes has developed a Elasticsearch add-on to enable log management of the cluster. This is a combination of Elasticsearch, FLUENTD and Kibana. Elasticsearch is a search engine that is responsible for storing logs and providing query interfaces; Fluentd is responsible for collecting logs from Kubernetes and sending Elasticsearch;kibana a Web GUI that users can browse and search for stored in Logs in th

Haven't written a blog for a long time, the company engaged in a period of 997 is too brutal. 997 End also fast 1 weeks, finally slow down a bit, first two easy article, and then a little work, write a Kubernetes series.

Pokemon per second processing of Go cloud data storage (expected vs Actual) This can happen, and you should be prepared for it as well. This is also the article in this series to mention. In this series of tutorials we'll show you what you need to track, why you're tracking them, and what you need to do to deal with possible root causes. We'll show you each indicator, how to track it, and what you can do to take action. We will use different tools to collect and analyze this data.

Tags: composition instance provider application Application class version style implementationThe lifespan of kubernetes pods is limited and they are not resurrected, so although each pod has its own IP address, these IP addresses are unreliable and disappear as the pod dies. This poses a problem, if some of the pod's collections (called backends) are other pods of the cluster (called frontends), how do these frontends find and always know which backe

One of the most important tasks for today's aspiring people in the computer industry is to learn Java! So how should Java programmers and Java developers take the test, how should they take the test, and what should they pay attention to during the test?With the rapid development of the IT industry, obtaining authoritative certification provides more and more opportunities for personal development. Sun has three types of Java certifications: Java prog

Learning notes TF064: TensorFlow Kubernetes, tf064tensorflow AlphaGo: each experiment has 1000 nodes and each node has 4 GPUs and 4000 GPUs. Siri: 2 nodes and 8 GPUs for each experiment. AI research relies on massive data computing, instead of performance computing resources. The larger cluster running model shortens the weekly training time to the day-level hour level. Kubernetes, the most widely used cont

The bottom of the Kubernetes node is supported by a software called a "container runtime," which is responsible for things like starting and stopping containers. The most well-known container runtime is Docker, but it is not unique. In fact, this field has developed rapidly in the container runtime. To make the expansion of kubernetes easier, we have been polishing the k8s plug-in API that supports containe

After the initial completion of the Kubernetes cluster architecture, by building some monitoring components, we have been able to achieve Graphical monitoring of status information and resource conditions for each node,pod Scaling and scaling of replicateset through scale View the run log for each pod by kubectl logs or dashboard However, the scale of the nodes in the distributed architecture is often very large, a typical produc
