KubeSphere 是 GitHub 上的一个开源项目,是成千上万名社区用户的聚集地。很多用户都在使用 KubeSphere 运行工作负载。对于在 Linux 上的安装,KubeSphere 既可以部署在云端,也可以部署在本地环境中,例如 AWS EC2、Azure VM 和裸机等。
KubeSphere 为用户提供轻量级安装程序 KubeKey(该程序支持安装 Kubernetes、KubeSphere 及相关插件),安装过程简单而友好。KubeKey 不仅能帮助用户在线创建集群,还能作为离线安装解决方案。
以下是可用的安装选项:
注意:并非所有选项都相互排斥,例如,您可以在离线环境中使用最小化安装将 KubeSphere 部署在多个节点上。
本文主要介绍在Linux系统下离线安装KubeSphere
要开始进行多节点安装,您需要参考如下示例准备至少三台主机。
主机 IP | 主机名称 | 角色 | 系统版本 |
---|---|---|---|
172.31.10.2 | node1 | 联网主机用于制作离线包 | Ubuntu20.04 LTS |
172.31.10.43 | node2 | 离线环境主节点 | Ubuntu20.04 LTS |
172.31.10.44 | node3 | 离线环境镜像仓库节点 | Ubuntu20.04 LTS |
在私有云上创建3台云主机如下,物理机也可以
KubeKey 是一个用于部署 Kubernetes 集群的开源轻量级工具。它提供了一种灵活、快速、便捷的方式来仅安装 Kubernetes/K3s,或同时安装 Kubernetes/K3s 和 KubeSphere,以及其他云原生插件。除此之外,它也是扩展和升级集群的有效工具。
KubeKey v2.1.0 版本新增了清单(manifest)和制品(artifact)的概念,为用户离线部署 Kubernetes 集群提供了一种解决方案。manifest 是一个描述当前 Kubernetes 集群信息和定义 artifact 制品中需要包含哪些内容的文本文件。在过去,用户需要准备部署工具,镜像 tar 包和其他相关的二进制文件,每位用户需要部署的 Kubernetes 版本和需要部署的镜像都是不同的。现在使用 KubeKey,用户只需使用清单 manifest 文件来定义将要离线部署的集群环境需要的内容,再通过该 manifest 来导出制品 artifact 文件即可完成准备工作。离线部署时只需要 KubeKey 和 artifact 就可快速、简单的在环境中部署镜像仓库和 Kubernetes 集群。

注意:
若需要导出的 artifact 文件中包含操作系统依赖文件(如:conntarck、chrony 等),可在 operationSystem 元素中的 .repostiory.iso.url 中配置相应的 ISO 依赖文件下载地址或者提前下载 ISO 包到本地在 localPath 里填写本地存放路径并删除 url 配置项。
开启 harbor 和 docker-compose 配置项,为后面通过 KubeKey 自建 harbor 仓库推送镜像使用。
默认创建的 manifest 里面的镜像列表从 docker.io 获取。
可根据实际情况修改 manifest-sample.yaml 文件的内容,用于之后导出期望的 artifact 文件。
