Docker is a product that allows developers to create containers, which are selfcontained areas on their computer for running applications. They can be used for databases, which is great if you can't install it normally (e.g. you use a Mac).

This video shows you how to set up a PostgreSQL database on Docker. It uses an existing PostgreSQL image on the Docker Hub website. You can use many different versions of PostgreSQL, not just the latest version.

You'll learn how to download and install Docker, find the right PostgreSQL image, download the image, run it, and connect to it in the DBeaver IDE. You can use any other IDE that works with PostgreSQL if you prefer.

The connection details for this image mentioned in the video are below.

Host: localhost
Port: 5432
Username: postgres
Password: whatever you specify in the "docker run" command (default is mysecretpassword)
