Sealos 部署 Kubernetes 集群

Last updated on

本文档用于在虚机环境中使用 Sealos 快速部署 Kubernetes 集群单节点环境。

准备工作​

  • 单台 8C16G 纯净虚机。
  • 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。
  • 支持使用 Containerd 作为容器运行时。
  • 一定需要 root 用户部署

联网环境部署 Sealos Kubernetes​

mkdir /opt/sealos
cd /opt/sealos
curl http://storage.kindlingx.com/package/sealos-k8s/sealos-k8s-deploy-v1.1.0-online.sh | bash

离线环境部署 Sealos Kubernetes​

下载离线安装包

mkdir ./sealos
cd ./sealos
curl http://storage.kindlingx.com/package/sealos-k8s/sealos-k8s-package-download-v1.1.0.sh | bash

执行下方命令检查安装包

ls -l # ~/sealos
total 951232
-rw-r--r--. 1 root root 351843328 Aug 16 16:02 calico-v3.24.1.tar
-rw-r--r--. 1 root root  17112576 Aug 16 16:00 helm-v3.14.0.tar
-rw-r--r--. 1 root root 411297280 Aug 16 16:01 kubernetes-v1.25-latest.tar
-rw-r--r--. 1 root root 130833408 Aug 16 16:02 openebs-v3.10.0.tar
-rw-r--r--. 1 root root      1175 Aug 16 16:02 sealos-k8s-deploy-v1.1.0.sh
-rw-r--r--. 1 root root  62963267 Aug 16 16:00 sealos_4.3.7_linux_amd64.tar.gz

将sealos文件夹下所有文件移动到目标部署机器的/opt/sealos文件夹下，并在/opt/sealos文件夹下执行命令：

bash sealos-k8s-deploy-v1.1.0.sh

验证​

脚本执行完成后预期有类似输出
