Deploy on timeweb.com 1GB VPS server (I chose the cheapest option: ~2.7 USD a month for VPS with 3.3GHz CPU, 1GB RAM, 15 GB HHD):

0. Install Bitvise SSH Client (or PUTTY) - https://www.bitvise.com/ssh-client-download

1. Setup Docker on Ubuntu 22.04 - https://timeweb.cloud/tutorials/docker/kak-ustanovit-docker-na-ubuntu-22-04

2. Make a swap file from HDD for supporting RAM - https://timeweb.cloud/docs/unix-guides/creating-and-resizing-swap

3. Run docker with interactive terminal, auto restarting, and memory management:
$ docker run -it --restart always --memory 1GB --memory-swap -1 gelert/repo:bot
or with cpu limiting
$ docker run -it --restart always --cpus 4 --memory 1GB --memory-swap -1 gelert/repo:bot

Docker memory management - https://docs.docker.com/config/containers/resource_constraints/#--memory-swap-details
