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

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

The Traefik principle can be consulted in the official documentation: https://docs.traefik.io/, This document can also be consulted about the service exposure of kubernetes and the rationale for using Traefik as a kubernetes ingress: https://mritd.me/2016/12/06/ Try-traefik-on-
