in the previous section we discussed the services running on the Kubernetes architecture Master,This section discusses node nodes. Node is where the Pod runs, Kubernetes supports Docker, Rkt, and other container runtime. The Kubernetes components running on node have Kubelet, Kube-proxy, and Pod networks (such as flannel).KubeletKubelet is the agent of node, and

GlusterFSGlusterfs is an open-source, scale-out file system. These examples provide information about how to allow containers to use glusterfs volumes.The example assumes that you have set up the Glusterfs server cluster and is ready to use the running Glusterfs volume in the container.PrerequisiteThe Kubernetes cluster has been built.Installation of the Glusterfs clusterEnvironment IntroductionOS System: Centos 7.xGlusterfs of two nodes: 192.168.22.2

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
