My ‘Janitor’ Script: Automating Server Maintenance with Bash & Docker.

I got tired of SSH-ing into my server to clean logs and prune Docker images. So I wrote a Cron job and deployed Watchtower.

Here is the exact Bash script I use to keep my Debian VM clean automatically every morning at 6:25 AM:

#!/bin/bash

# Clean logs
sudo /usr/local/bin/docker-systemctl restart zabbix

# Prune Docker images
sudo docker system prune -af

# Clean up Docker volumes
sudo docker volume rm $(docker volume ls -f dangling=true -q)

# Clean up unused Docker networks
sudo docker network rm $(docker network ls -q -f is-isolated=true)

# Reboot the server
sudo shutdown -r now

With this script, I can ensure my server is always in a healthy state, even when I’m not around.
