kubernetes federation

Kubernetes is Google 's Open source container cluster management system. It is built on Docker technology and provides a whole set of functions, such as resource scheduling, deployment operation, service discovery, expansion and contraction capacity, for containerized applications, which can be regarded as Mini-paas platform based on container technology. The purpose of this article is to comb the architecture, concepts, and basic workflows of

Service discovery mechanism Kubernetes provides two ways to discover the service:1. Environment Variables When the pod is running, Kubernetes writes the information for the service that existed before This method requires that the pod must be started after the service. The pod that was started before the service will not have an environment variable for that service. There is no such limit in the way

There are several ways to install the Kubernetes cluster, the KUBEADM approach is described earlier, and the manual installation method is described in this article.The installation environment has 3 VMS on Azure:HKUBE01:10.0. 1.4 HKUBE02: 10.0. 1.5 Hbube03: 10.0. 1.6Where hkube01 is the master node, it will install Docker, ETCD, Kubernetes Master, flannel required components;HKUBE02 and hkube03 are worker

1. Bash Auto-refill for KUBECTL commandsThis is probably the easiest thing to do in the kubernetes process, but it's also one of the most useful. To add the auto-refill feature, if you use bash, simply execute the following command:echo"sourceIt will add an auto-complete command to your. bashrc file. So each shell window you open supports this feature. I found that auto-completion is especially useful for some long parameters, such as--all-namespaces.

How to build a Kubernetes (k8s) Environment The official version of k8s is updated too quickly. Many articles on the Internet are outdated and many tools and interfaces have changed. the official website does not have a good understanding. Here we only record the process of setting up the k8s environment and will not talk about many k8s concepts. Therefore, we recommend that you first understand various concepts and then build the environment, then, i

Helm IntroductionDeploying container cloud Applications (container or microservices orchestration) in Kubernetes is a challenging task, Helm is to simplify the installation of a client tool for deploying container cloud applications in Kubernetes. Helm enables developers to define, install, and upgrade container cloud applications in Kubernetes. At the same time,

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
