安装 Kubeasz 非常简单只需要从 GitHub 下载 Kubeasz 的源码然后运行相应的 Ansible 脚本即可。
1.下载 Kubeasz 的源码
#这里安装的是3.5.0 K8S是v1.26.0
export release3.5.0
wget https://github.com/easzlab/kubeasz/releases/download/${release}/ezdown
chmod x ./ezdown# 国内环境
./ezdown -D
# 海外环境
#./ezdown -D -m standard#./ezdown -X #【可选】下载额外容器镜像cilium,flannel,prometheus等
#./ezdown -P #【可选】下载离线系统包 (适用于无法使用yum/apt仓库情形)# 容器化运行kubeasz
./ezdown -S
docker ps -a #看到了2个启动的容器#创建新集群 k8s-01
docker exec -it kubeasz ezctl new k8s-01 #安装
cd /etc/kubeasz/clusters/k8s-01/
# /etc/kubeasz/clusters/k8s-01/hosts
# /etc/kubeasz/clusters/k8s-01/config.ymlcat /etc/kubeasz/clusters/k8s-01/hosts EOF #这里的配置就是看你的etcd,k8s集群几个master,node都在这里配置
