This post is largely the result of:

  1. Jonathan Adams (@RebelActuary) and his wonderful presentation over docker
  2. Alvise Susmel (@alvisesus) and his blog post about using Postgres and Docker

Thank you both.

Database Sandbox

Rather than spending the time installing and configuring a database locally, start coding faster with docker-compose. Start a Postgres server with docker-compose up -d. Stop the server with docker-compose down.

# docker-compose.yml

version: "3"
    image: postgres:11-alpine
    container_name: "postgres"
      - "5432:5432"
      - postgres-dev:/var/lib/postgresql/data
      - POSTGRES_PASSWORD=postgres

This file contains the settings outlined in the Postgres and Docker post.

  • image: this selects the version of Postgres to run,
  • container_name: the name of the container,
  • ports: the port mapping between the local machine and container,
  • volumes: mounts the volume to the container to persist the data between runs,
  • environment: sets the Postgres password as an environment variable

Hopefully this helps speed up your development speed!
