A Redis+Flask 'Hello World' app on Docker Fig

HelloWorldRedisDocker

Testing Docker multi-container app implementation using Fig and container linking. Modified example from http://www.fig.sh

Assumptions:

• Docker and Fig is installed on the running host
• Docker installation instructions: https://docs.docker.com/installation/
• Fig installation instructions: http://www.fig.sh/install.html

Files:

• Dockerfile - Dockerfile to build web-tier container
• fig.yml - Fig file describing the multi-container app environment
• requirements.txt - File describing pip dependencies for web container build
• /code/HelloWorldRedis.py - 'Hello World' Python Flask web app that increments counter in Redis and prints it out

To start: $ fig up

To access: $ curl ($ip):5000

Note:

• Lowercase repo/encasing folder name is required to avoid an issue that causes the web container build from the Dockerfile to fail
  • Issue reference: docker/compose#655
