前言

手动部署k8s太过于痛苦，随即发现kubekey这样的工具。

kubekey

准备工作：wget <https://github.com/kubesphere/kubekey/releases/download/v3.1.1/kubekey-v3.1.1-linux-amd64.tar.gz> && tar zxvf kubekey-v3.1.1-linux-amd64.tar.gz

cluster.yaml

在线部署

1.安装harbor(不需要的可以跳过)

  1. 上传cluster.yaml文件，将ip地址都替换为当前主机IP
  2. export KKZONE=cn # 使用国内的镜像安装
  3. ./kk init registry -f cluster.yaml

2.安装k8s集群

  1. yum install conntrack -y && yum install socat -y
  2. sh create_project_harbor.sh # 跳过harbor安装的，这一步也可以跳过
  3. ./kk create cluster f cluster.yaml

3.验证

kubectl get node 查看集群状态

\可选 仓库验证：https://ip+443（admin/Harbor12345）

离线部署

无法访问外网情况

0.所需文件说明

kubekey-v3.1.1-linux-amd64.tar.gz

images.tar.gz: 通过export KKZONE=cn ./kk create manifest --with-kubernetes v1.28.6 --with-registry && ./kk artifact export -m manifest-sample.yaml -o image.tar.gz

cluster.yaml: 文件详情

rpm.tar.gz: 包含conntrack和socat， 下载地址

create_project_harbor.sh: 下载地址

1.安装kubekey

上传kubekey-v3.1.1-linux-amd64.tar.gz文件
