Controller Manager 有很多具体的 Controller,在文章Components of Kubernetes Architecture中提到的有 Node Controller、Service Controller、Volume Controller 等。Controller 负责监控和调整在 Worker Node 上部署的服务的状态,比如用户要求 A 服务部署 2
The CCM consolidates all of the cloud-dependent logic from the preceding three components to create a single point of integration with the cloud. The new architecture with the CCM looks like this image TODO Extending the Kubernetes API Custom Resources Custom resources Custom controllers CustomResourc...
To truly grasp Kubernetes architecture, you need to understand its core principles and components. Kubernetes, often abbreviated as K8s, is an open-source platform designed to automate the deployment, scaling, and operation of application containers. It manages containerized applications across multiple ...
Kubernetes Architecture and Components Kubernetes has a decentralized architecture that does not handle tasks sequentially. It functions based on a declarative model and implements the concept of a ‘desired state.’ These steps illustrate the basic Kubernetes process: An administrator creates and places ...
Controller Manager 有很多具体的 Controller,在文章Components of Kubernetes Architecture中提到的有 Node Controller、Service Controller、Volume Controller 等。Controller 负责监控和调整在 Worker Node 上部署的服务的状态,比如用户要求 A 服务部署 2 个副本,那么当其中一个服务挂了的时候,Controller 会马上调整,让 ...
用图来表示体系结构,是阐述 Kubernetes 最快的方式,下面是一张称为Kubernetes Architecturegraphic 。 上图是简单的 kubernetes 结构,左侧虚线方框中,是 master 节点,运行着各种各样的组件,master 节点负责控制整个集群,当然在很大的集群中也可以有多个 master 节点;而右侧是三个工作节点,负责运行我们的容器应用。这种...
monitoring_architecture.png 监控架构分两部分内容:核心监控(图白色部分)和自定义监控(图蓝色部分) 1、 核心监控实现 通过kubelet收集资源估算+使用估算 metric-server负责数据收集,不负责数据存储 metric-server对外暴露Metric API接口 核心监控指标客用户HPA,kubectl top,scheduler和dashboard ...
While Kubernetes’ architecture and set of internal components can at first seem daunting, their power, flexibility, and robust feature set are unparalleled in the open-source world and for cloud native development. By understanding how the basic building blocks fit together, you can begin to ...
首先看下图,图片来自文章Components of Kubernetes Architecture: K8S是属于主从设备模型(Master-Slave架构),即有Master节点负责核心的调度、管理和运维,Slave节点则在执行用户的程序。但是在K8S中,主节点一般被称为Master Node或者Head Node(本文采用Master Node称呼方式),而从节点则被称为Worker Node或者Node(本文采用...
Kubernetes is a platform for running applications and services. It manages the full lifecycle of container-based applications, by automating tasks, controlling resources, and abstracting infrastructure.
