kubeasz部署k8s集群1.37

在部署节点配置ssh免密码登录其他节点

下载ezdown，我这里在的是最新版3.6.8

bash 复制代码

export release=3.6.8
root@ubuntu:~# wget https://github.com/easzlab/kubeasz/releases/download/${release}/ezdown
chmod +x ./ezdown

修改ezdown文件可以指定k8s等组件版本

执行 ./ezdown -D 下载kubeasz代码、二进制、默认容器镜像

我通过修改ezdown安装k8s最新版1.37.7，但是kubeasz很多镜像还没有发布，安装有很多问题，还是安装默认的版本

bash 复制代码

2026-04-17 02:30:17 [ezdown:312] INFO downloading kubernetes: v1.34.7 binaries
Error response from daemon: Get "https://registry-1.docker.io/v2/": context deadline exceeded
2026-04-17 02:30:56 [ezdown:790] ERROR Action failed: download_all

只需要加一行环境变量：export REGISTRY_MIRROR=https://docker.m.daocloud.io 配置其他地方下载镜像？

#容器化运行kubeasz，用于安装k8s集群工具

./ezdown -S

创建集群的初始的配置信息,指定集群名称 k8s-01

bash 复制代码

root@ubuntu:~# docker exec -it kubeasz ezctl new k8s-01
2026-04-17 11:07:27 [ezctl:145] DEBUG generate custom cluster files in /etc/kubeasz/clusters/k8s-01
2026-04-17 11:07:27 [ezctl:151] DEBUG set versions
2026-04-17 11:07:27 [ezctl:182] DEBUG cluster k8s-01: files successfully created.
2026-04-17 11:07:27 [ezctl:183] INFO next steps 1: to config '/etc/kubeasz/clusters/k8s-01/hosts'
2026-04-17 11:07:27 [ezctl:184] INFO next steps 2: to config '/etc/kubeasz/clusters/k8s-01/config.yml'

修改 /etc/kubeasz/clusters/k8s-01/hosts，配置节点信息

bash 复制代码

cat  /etc/kubeasz/clusters/k8s-01/hosts
[etcd]
192.168.1.131
192.168.1.132
192.168.1.133

[kube_master]
192.168.1.131 k8s_nodename='master-01'
192.168.1.132 k8s_nodename='master-02'
192.168.1.133 k8s_nodename='master-03'

[kube_node]
192.168.1.134 k8s_nodename='worker-01'
192.168.1.135 k8s_nodename='worker-02'
192.168.1.136 k8s_nodename='worker-03'

一键部署所有

root@ubuntu:~# dk ezctl setup k8s-01 all

部署完成后拷贝kubectl命令到各节点

bash 复制代码

cp /etc/kubeasz/bin/kubectl /usr/local/bin/
root@ubuntu:~# for s in {131..136};do scp /etc/kubeasz/bin/kubectl 192.168.1.$s:/usr/local/bin/;done

配置命令补全

bash 复制代码

kubectl completion bash > /etc/bash_completion.d/kubectl
source /etc/bash_completion.d/kubectl # 立即生效
