Docker Hub 镜像加速器

国内从 Docker Hub 拉取镜像有时会遇到困难，此时可以配置镜像加速器。

Dockerized 实践 https://github.com/y0ngb1n/dockerized

1️⃣ Docker daemon 配置代理（推荐）

#如果没有root的话(gateway没法设, dns也没法设), 则不使用系统的usb tethering而是使用gnirehtet而更简单些:
https://github.com/Genymobile/gnirehtet
sudo iptables -t nat -A OUTPUT -p udp ! -d 127.0.0.1 --dport=53 -j DNAT --to 192.168.0.25:53
./gnirehtet run
(可以设置unbound.conf的verbosity: 3<\n> logfile: unbound.log<\n> log-queries: yes 来观察是否生效, log文件位置可以用lsof -c unbound看到)
用来收android的更新包非常快, 打google voice也是这个gnirehtet+iptables可以用, 用手机上的lantern或wireguard应用都不行

#手机usb线连pc并启用tether
(manual switch on: settings/network & internet/hotspot & tethering/usb tethering
default on: settings/system/developer/networking/select usb configuration/rndis(usb ethernet)
