Express app with Redis and nodemon development server

In this step we'll link a Redis container to the app from step 01.

Prerequisites

Install Docker on your system.

• Install instructions for Mac OS X
• Install instructions for Ubuntu Linux
• Install instructions for other platforms

Install Docker Compose on your system.

Setup

1. Run docker-compose build. This will pull the base images, and install image dependencies.

2. Run docker-compose run web npm install. This will install the package.json dependencies in the app sub-folder. Since this folder is mounted into the Docker image as a volume, any changes made in the image or on your local file system are synced.

Start

Run docker-compose up to start the container. The app should then be running at http://localhost:3000.
