Running a Transient Instance
Postgres binds by default on port 5432 and this is the port published by the following command:
docker run -p 5432:5432/tcp posgres
The command will implicitly create a local anonymous volume that will linger around after the container stops. The data on the anonymous local volume can be accessed by starting the stopped container.
