DO NOT USE LATEST v2rayNG! Download last good version here https://github.com/2dust/v2rayNG/releases/tag/2.2.1
请不要升级最新版xray-core或v2ray NG，你将被强制要求安全。上面链接下载2.2.1不安全版本，以免被安全。

Disclaimer

This is for demo only. This script is insecure (password is public), unreliable (docker img might be deleted), unsupported (don't cry if not working). And it's assuming you already know how to use v2ray app.

The intention is for my personal use only.
