Deploying Multiple Python Bots to a Single Railway Container

A tutorial for running two or more python bots on Railway inside one container and one service, with independent crash recovery for each. Deploying Multiple Python Bots to a Single Railway Container If you're running more than one Python bot — say, a Telegram ingestion bot and a Discord notification bot that share a database — deploying each as its own Railway service means double the hosting cost and double the configuration for something that's logically one unit. This tutorial covers deploying both bots inside a single Railway container, with each one still getting fully independent crash recovery.

If two bots are closely related — sharing a database, a queue, or just conceptually belonging to the same project — running them as two separate Railway services duplicates all of that for no real benefit. The Naive Fix and Why It Falls Short A common first instinct is a shell script: python telegram_bot.py & python discord_bot.py & wait This runs both, but there's no real process supervision here — if telegram_bot.py crashes, nothing restarts it, and you still haven't solved Railway's HTTP port requirement, since neither script opens one.
