etcd kubernetes

Kubernetes can connect pods on different node nodes in the cluster, and by default, each pod is accessible to each other. However, in some scenarios, different pods should not be interoperable, and access control is required at this time. So how does it work?Brief introduction?? Kubernetes provides Networkpolicy feature, which supports network access control by namespace and by pod level. It uses the label

always, it starts with access-servers, virtual machines, applications, office mail, and so on. If you are or want to be a customer of one of the major enterprise platforms (IBM, Google, Microsoft), the access issue will be handled by one of the vendors ' services. But if you want to have your own solution, can it be managed only by you and within your budget?This list helps you determine the appropriate solution and estimate the amount of work required to set up and maintain. Of course, your ch

: apiserver: As the entrance of the kubernetes system, it encapsulates the additions and deletions of core objects, which are provided to external customers and internal component calls in a restful interface. The rest objects it maintains are persisted to ETCD, a distributed, strongly-consistent key/value store. Scheduler: Responsible for the resource scheduling of the cluster, assi

Kube-dns is made up of four containers, and the roles they play can be understood by the following Diagram.whichSkydns is an open-source framework for service discovery, built on ETCD.

In the first two parts of this series we describe the overall process of API server and how the API objects are stored in ETCD. In this article we will explore how to extend the API resources.In the beginning, the only way to extend the API resources is to extend the relevant API source code and integrate it into the resources you need. Or, push a whole new type into the community code for the new core object API. However, this can lead to a constant

Master Node component kube-apiserver 用于暴露kubernetes API，不管是kubectl 还是HTTP 调用来操作kubernets 集群各种资源，都是通过kube-apiserver 提供的接口进行操作的，Node 节点与Master之间的通信也是主要依赖于kube-apiserver，例如pod调度: kube-scheduler 将调度结果写入etcd，kubelet 监听etcd 获取到调度任务。 ETCD 一款用于共享配置和服务发现的高效KV存储系统，具有分布式、强一致性等特点，在kubernet
