很多 binary 文件 都在国外。比如 Kube 。国内下载很慢，需要加速。
- 一个简洁有效的方法能够加速这些包。简洁的名称映射
- 易于添加，添加新的包，不需要去修改代码。
- 稳定可靠，更新实时。
- 可以直接用于 kubespray
在原始 URL 上面加入 files.m.daocloud.io 的 前缀 就可以使用。比如：
# Helm 下载原始URL
wget https://get.helm.sh/helm-v3.9.1-linux-amd64.tar.gz
# 加速后的 URL
wget https://files.m.daocloud.io/get.helm.sh/helm-v3.9.1-linux-amd64.tar.gz即可加速下载, 所以如果指定的文件没有被缓存, 会卡住等待缓存完成, 后续下载就无带宽限制。
cd /tmp
export HELM_VERSION="v3.9.3"
wget "https://files.m.daocloud.io/get.helm.sh/helm-${HELM_VERSION}-linux-amd64.tar.gz"
tar -zxvf helm-${HELM_VERSION}-linux-amd64.tar.gz
mv linux-amd64/helm /usr/local/bin/helm
helm version加入如下配置即可：
