一些国内镜像源设置

NPM

npm config set registry https://registry.npm.taobao.org

换回来：

npm config set registry https://registry.npmjs.org

若是只想生效一次：

npm --registry=https://registry.npm.taobao.org install xxxxx

Docker

编辑文件： C:\Users\chensf1\.docker\daemon.json

在 registry-mirrors 里添加 https://registry.docker-cn.com，以下：

{"registry-mirrors":["https://registry.docker-cn.com"],"insecure-registries":[], "debug":true, "experimental": false}

alpine

sed -i 's/http:\/\/dl-cdn.alpinelinux.org/https:\/\/mirror.tuna.tsinghua.edu.cn/' /etc/apk/repositories
