V2Ray with outbound address (cursed way)

!v2ray-docker-compose-README.md

There're some Docker-ized configuration files to setup a weird proxy.
Since V2Ray doesn't support specifiy outbound address yet,
placing a Shadowsocks instance with -b option behind the V2Ray server is less complex than policy routing in the kernel.

The whole proxy chain for this VMess over WebSocket:
Reverse Proxy (NGINX, etc.) -> V2Ray (WebSocket -> VMess) -> Shadowsocks

• Multiple instances of V2Ray and load balancing (if necessary?)
• Retrieve parameters in JSON files from environment
