It’s also important to mention that you can also deploy a single-node Kubernetes cluster which is generally recommended for very light, non-production workloads. For this, you can useMinikube, which is a tool that runs a single-node Kubernetes cluster in a virtual machine on your node. Rec...
首先要明确,一旦 kubernetes 环境启动之后,master 和 node 都会将自身的信息存储到 etcd 数据库中 一个nginx 服务的安装请求会首先被发送到 master 节点的 apiServer 组件 apiServer 组件会调用 scheduler 组件来决定到底应该把这个服务安装到哪个 node 节点上 在此时,它会从 etcd 中读取各个 node 节点的信息,然后按...

一、Cluster、Master、Node 介绍 1,Cluster Cluster(集群) 是计算、存储和网络资源的集合,Kubernetes 利用这些资源运行各种基于容器的应用。 最简单的 Cluster 可以只有一台主机(它既是 Mater 也是 Node) 2,Master Master 是 Cluster 的大脑,它的主要职责是调度,即决定将应用放在哪里运行。
OpenEBS provides enterprise-grade data management for Kubernetes clusters, with five storage engines (four single-node and one replicated) that meet a range of use cases for Kubernetes users. The five engines are summarized in the table below: ...
