配置镜像加速（TODO 配置阿里云加速待完善）

cat >> /etc/rancher/k3s/registries.yaml <<EOFmirrors:  "docker.io":    endpoint:      - "https://docker.mirrors.ustc.edu.cn" # 可根据需求替换 mirror 站点      - "https://registry-1.docker.io"EOFsystemctl restart k3s

部署命令

访问需要魔法，可以把文件下载到本地，在上传到服务器，再执行

kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v2.7.0/aio/deploy/recommended.yaml

需要自己映射一个外部端口，注释部分修改2个地方

片段
