PostgreSQL with Docker

Internal

• PostgreSQL

Overview

This article describes how to stand up and operate a Docker-based PostgreSQL instance. The instance will be accessible on the standard PostgreSQL port on the local host and it will be secured by a conventional user and password. Since the password is visible in the terminal used to create the container image, this approach is not really secure, but it is good enough for development purposes. The container-generated data will be stored on an anonymous local volume.

Procedure

Create the Container

This is an one-time operation:

docker run -p 5432:5432/tcp -e POSTGRES_USER=admin -e POSTGRES_PASSWORD=<some-password> --name postgres postgres 

Start the Container

docker start postgres

Stop the Container

docker stop postgres

Access Container Logs

docker logs -f postgres
