Kubernetes is a Borg open source-based container Orchestration Scheduler that manages the open source platform for automated deployment, expansion, and operation of container clusters. As one of the most important components of the CNCF (Cloud Native Computing Foundation) (CNCF another project Prometheus), its goal is not just an orchestration system, but a specification that allows you to describe the architecture of the cluster, Define the final sta

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

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 Many articles on the Internet are outdated and many tools and interfaces have changed.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

Docker Network BasicsSince Kubernetes is based on the Docker container as the carrier of the application release, the network characteristics of Docker also determine that kubernetes in building a container interoperability network must solve the problem of Docker's own network.Network namespacesTo support multiple instances of the network protocol stack, Linux introduces a network namespace in the network

-speed storage to store a large number of fragmented files. What the user needs to do is submit the resource request to the cloud platform and then fetch and consume the storage resource without worrying about which disk of the storage server The underlying store is from. to meet the storage needs of container users in the cloud environment. Kubernetes provides the concept of persistent volumes (PERSISTENTVOLUME,PV) and persistent volume requests (PE
