基于 SealOS 安装​

前置条件​

  • 每个集群节点应该有不同的主机名。 主机名不要带下划线
  • 所有节点的时间同步
  • 在 Kubernetes 集群的第一个节点上运行sealos run命令，目前集群外的节点不支持集群安装
  • 建议使用干净的操作系统来创建集群。不要自己装 Docker
  • 支持大多数 Linux 发行版，例如：Ubuntu CentOS Rocky linux
  • 支持 DockerHub 中支持的 Kubernetes 版本
  • 支持使用 containerd 作为容器运行时
  • 在公有云上请使用私有 IP

二进制下载​

$ wget https://github.com/labring/sealos/releases/download/v4.0.0/sealos_4.0.0_linux_amd64.tar.gz \
   && tar zxvf sealos_4.0.0_linux_amd64.tar.gz sealos && chmod +x sealos && mv sealos /usr/bin

安装 KubeGems​

sealos run \
  --masters xxx,xxx --nodes xxx,xxx,xxx -p pwd \
  labring/kubernetes:v1.23.10 \
  labring/helm:v3.8.2 \
  labring/calico:v3.22.1 \
  labring/coredns:v0.0.1 \
  labring/openebs:v1.9.0 \
  kubegems/kubegems-stack:v1.23
KubeGems stack 版本

您可以在访问 Docker DockerHub 仓库查找 kubegems/kubegems-stack 的镜像版本

提示

通过 SealOS 一键安装的 KubeGems 数据存储在 OpenEBS 的LocalPV 上，它位于某一台物理机上，不具备数据迁移功能。

如果您的环境具备共享存储或者更高规格的存储服务，建议您使用 SealOS 只用于部署 Kubernetes 集群！

安装成功后，您将看到如下打印的信息
