directly on machine

To get servers cheaper than 100 EUR with more than 24GB of RAM, disks at least 3TB:

python3 -m venv .
source ./bin/activate
python3 -m pip install -r requirements.txt

./hah.py --price 38 --disk-size 3000 --ram 24

You'll probably want to put it in crontab.

docker

Run in test mode or change path "${HOME}/Library/Application Support/telegram-send.conf" to where your local telegram-send installed config.

docker build . -t hetzner-auction-hunter:latest

docker run --rm \
  -v "${HOME}/Library/Application Support/telegram-send.conf":/etc/telegram-send.conf \
  -v /tmp/hah:/tmp/ \
  hetzner-auction-hunter:latest --price 38 --disk-size 3000 --ram 24

telegram-send does not support ENV variables as source of token or chat ID.
