Demo application used for Docker Blacksburg Meetup

Docker Compose Demo

This repo contains a simple demo that was built for the Docker Blacksburg Meetup on October 12, 2016.

Application Overview

The application is a simple PHP application that relies on a MySQL database. The database contains a collection of users, with their respective emails, passwords (using a terrible plain-text version for demo), creation date, and an active flag. The PHP app simply outputs a table with all user data.

Running the Default Composition

The default docker-compose.yml file is using the image directive to specify a named image. Obviously, in order for this to work, you need to build the images.

docker build -t my-mysql ./docker/mysql
docker build -t my-php ./docker/php
docker-compose up

Then, open your browser to http://localhost/ to see the application. You should see a simple table containing all users in the database.

Making it Better

Obviously, it's a pain to have to build the images first. So, the docker-compose-build.yml file uses the build directive to build the images to be used in the composition.

docker-compose -f docker-compose-build.yml up
