Challenge 1 / 1

Postgres databases typically start on port 5432. In this tutorial, we ran this command:

psql --user=symfony --port=50700 --host=127.0.0.1 --password app

Why is our database running on port 50700?

Our docker-compose.yml file contains configuration that tells Postgres to start on port 50700 to avoid conflicts.

The database is running on port 5432 inside the Docker container, but then that port is exposed to 50700 on my "host" machine. 50700 is a random port chosen by Docker.
