Overview
A transient Posgres container instance can be started and exposed on a local host port as shown in the section.
- simplest image - data is lost

Running a Transient Instance
docker run 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.
