PostgreSQL with Docker

Internal

• Postgresql

Overview

A transient Posgres container instance can be started and exposed on a local host port as shown in the Running a Transient Instance section.

• simplest image - data is lost
• external volume
• port mapping.

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  postgres

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.
