作者：李茂福 更新日期：2023-12-29 ## ★第 0 章、K8S 集群搭建准备工作 ## 相关单词原义： docker 码头工人 pod 集装箱 kubernetes 舵手，领航员 helm 舵轮，驾驶盘 chart 图表，海图 ## ① k8s 对系统要求 linux 内核在 3.10 及以上，服务器规格 2 核 cpu，2G 内存及以上，可以装在虚拟机里，也可以装在实体机上 ★第 14 章、Helm 包管理 helm 就是 k8s 的应用程序包管理器，helm 将 k8s 应用的相关资源配置文件组织为 Charts Charts 就是一个 helm 程序包， ★安装 helm ①helm v3 ★Helm v3 不再使用 tiller，直接使用 helm 命令即可 helm 开源地址： https://github.com/helm/helm 下载压缩包到 服务器上，并解压，把解压目录下的 helm 可执行文件复制到 /usr/bin/ 目录下添加可执行权限即可 helm 和 kubectl 一样默认读取 $HOME/.kube/config 配置文件去获取操作 k8s 集群的权限 ## ② helm v2 helm v2 需要使用 tiller, 运行于 k8s 集群上，需要使用一个 ServiceAccount # vi tiller-cluster-admin

We will deploy the Prometheus stack using Helm Chart. We will discuss the Helm chart in Section 5 in detail. Please note that the official helm chart for Prometheus needs persistent disk to start templates to Kubernetes templates at Rancher blog here. To install Prometheus, from Kubectl shell: helm install --name prom-release stable/prometheus Below is a quick overview of how each component participates
