Run PostgreSQL 18 on Ubuntu with Docker Compose in Minutes
This guide shows how to deploy PostgreSQL 18 on Ubuntu using Docker Compose with a named volume for persistence and secrets in a .env file. It binds the port to localhost only and adds a healthcheck for reliable container orchestration. The setup ensures data survives restarts and avoids exposing the database to the open internet.

Solid DevOps tutorial for reproducible Postgres setups, though experienced users may find the security basics (pin tags, localhost binding) already standard practice.
