前几篇文章中介绍了如何将 ruoyi-cloud 项目部署到 Kubernetes 集群中包括网关服务、认证服务和系统服务并且对全部服务采用 YAML 文件的方式来进行部署这虽然有助于理解 K8S 组织管理资源的风格与底层机制但是对于团队中不太熟悉命令行操作的成员不太友好这不现在我们借助由青云开源的容器平台 KubeSphere 来进行可视化的服务部署。 KubeSphere 是在 Kubernetes 之上构建的面向云原生应用的分布式操作系统完全开源支持多云与多集群管理提供全栈的 IT 自动化运维能力
接下来使用 KubeKey 完成 Kubernetes 与 KubeSphere 的一键安装。另外由于 CentOS7 在2024年即将停服实际部署不建议采用本次的部署环境采用 OpenEuler 社区创新版 23.09 。
Note如果是生产环境部署建议使用更稳定的 LTS 版本的操作系统eg: OpenEuler 22.03 SP3 。
虚机资源
共用到了三台虚机1台作为 Master 节点2台 Worker 节点。
主机名IP说明k1192.168.44.162主节点k2192.168.44.163工作节点k3192.168.44.164工作节点
即将安装的 KubeSphere 和 Kubernetes 版本信息如下

下载安装KubeKey
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。
# 下载安装KubeKey

Deploy a Kubernetes or KubeSphere cluster efficiently, flexibly and easily. There are three scenarios to use KubeKey.
1. Install Kubernetes only
2. Install Kubernetes and KubeSphere together in one command
3. Install Kubernetes first, then deploy KubeSphere on it using https://github.com/kubesphere/ks-installerUsage:kk [command]Available Commands:add Add nodes to kubernetes clusteralpha Commands for features in alphaartifact Manage a KubeKey offline installation packagecerts cluster certscompletion Generate shell completion scriptscreate Create a cluster or a cluster configuration filedelete Delete node or clusterhelp Help about any commandinit Initializes the installation environmentplugin Provides utilities for interacting with pluginsupgrade Upgrade your cluster smoothly to a newer version with this commandversion print the client version informationFlags:-h, --help help for kkUse kk [command] --help for more information about a command.配置准备工作
