A new Bash script streamlines securing a fresh Ubuntu server for production workloads. It automates installing Docker and Docker Compose, the UFW firewall, and Fail2Ban for SSH protection. This addresses the critical need for a hardened foundation before deploying applications.

The script updates the system, configures UFW to deny incoming traffic by default while allowing rate-limited SSH, and sets up Fail2Ban to block brute-force attacks. Adding the Fish shell is optional but improves the developer experience. This combination tackles common security oversights on new servers.

Automating these steps reduces human error, a frequent cause of server breaches. Developers can deploy containers faster while knowing their infrastructure has essential protections. The script provides a reproducible baseline, allowing teams to focus on application logic rather than manual server configuration.
