Running pgexercises in a container

A dedicated container for running a PostgreSQL instance for PGexercises

PostgreSQL Exercises provides exercises for learning SQL, using a Postgres instance. This is a reference on how to setup a dedicated environment using a Docker container.

Running the container

The official Docker image for Postgres will be used. Data is persisted in a named volume PGEXERCISES, mapped to the default path inside the container. We aren't defining a password, as the connection will be local (from inside the container).
