The function is to provide a DNS query interface for the pod in the Kubernetes cluster. The project is hosted on Https://github.com/skynetservices/skydns Etcd is an open-source, distributed, key-value storage that functions like zookeeper. The function in Kube-dns is to store the

I really can't find a reason to pay attention to it. Uttered, I've been using it Kubernetes for almost three months. About why I think it is very useful, with some ideas, although I am st

Apiserver is responsible for providing restful Kubernetes API service, it is the unified entrance of the System Management Directive, any operation that increases and deletions the resources should be handed over to apiserver processing and then submitted to ETCD. As shown in the architecture diagram, KUBECTL (t

Analysis of Kubernetes Application Deployment model (Principles) Abstract: this series of articles focus on actual deployment and give you a quick grasp of Kubernetes. This article describes the principles and concepts that need to be understood before deployment, including the Kubernetes component structure, functions of each component role, and

Once again, the architecture is clear: three virtual machine CentOS 7.4 systems, Docker 17, IP 10.10.90.105 to 107, 105-bit master, and the next master-related components installed on this machine.The ETCD cluster is 3 units, which are reused for each of the 3 virtual machines.As the core of k8s, the master node consists of three components, namely:Three components:kube-apiserverkube-schedulerkube-controller-managerThis three components are closely linked1.

With such a large amount of data, there may be thousands of machines behind it, unable to manually monitor the state of the machine. Therefore, this article introduces the use of the Kubernetes container management tool and, through a simple example, tells you how to build a Spark cluster. Preparation Phase 1. You need to have a running kubernetes cluster and use KUBECTL to configure access permissions for
