Support Local Bot API through proxy

[ZenonEl]

Description

Self-hosted Telegram Bot API (telegram-bot-api Docker image) needs to connect to Telegram servers. In regions where Telegram is blocked, it needs proxy support.

Options

1. proxychains in Docker — wrap telegram-bot-api binary with proxychains4 configured to use host SOCKS5 proxy
2. tun2socks — create a tun device that routes all traffic through SOCKS5
3. Docker network with Tor — add Tor container, route Bot API traffic through it
4. iptables + redsocks — transparent proxy at network level

Simplest approach

Option 1: Add proxychains to Dockerfile, configure via environment variable.

FROM aiogram/telegram-bot-api:latest
RUN apk add --no-cache proxychains-ng
COPY proxychains.conf /etc/proxychains.conf
ENTRYPOINT ["proxychains4", "telegram-bot-api"]

Config needed

• PROXY_HOST and PROXY_PORT environment variables
• proxychains.conf template with substitution
