# 安装 Kubernetes 系统依赖包
yum install -y curl socat conntrack ebtables ipset ipvsadm# 安装 tar 包不装的话后面会报错。openEuler 也是个奇葩迭代这么多版本了默认居然还不安装 tar
yum install tar3.安装部署 K8s
master节点:
下载 kk:
mkdir ~/kubekey
cd ~/kubekey/# 选择中文区下载(访问 GitHub 受限时使用)
export KKZONEcn
curl -sfL https://get-kk.kubesphere.io | sh -#查看 KubeKey 支持的 Kubernetes 版本列表
./kk version --show-supported-k8s创建 K8s 集群部署配置文件:
# 创建 K8s 集群部署配置文件
./kk create config -f k8s-v1288.yaml --with-kubernetes v1.28.8修改配置文件:
vi k8s-v1288.yaml# 修改配置文件

Before installation, ensure that your machines meet all requirements specified at
https://github.com/kubesphere/kubekey#requirements-and-recommendationsContinue this installation? [yes/no]:yesnfs client、ceph client、glusterfs client 3 个与存储有关的 client 显示没有安装。
docker、containerd 会根据配置文件选择的 containerManager 类型自动安装。
4.验证 K8s 集群
kubectl get nodes获取在 K8s 集群节点上已经下载的 Image 列表:
crictl images lskubectl get pod -A5.部署测试资源 kubectl create deployment nginx --imagenginx:alpine --replicas2kubectl create service nodeport nginx --tcp80:80kubectl get svc -o wide
