Pac-Man2

Applications Architecture Components

1. WebApp: NodeJS (boron)
2. Database: MongoDB (3.4)

MongoDB setup

1. Install locally, reference MongoDB's documentation
2. Install using docker (Install Docker on Ubuntu: https://docs.docker.com/engine/install/ubuntu/)

docker network create my-net
docker run --name pacman-mongo-0 --network my-net -p 27017:27017 -d mongo:3.4

NodeJS WebApp setup

Install dependencies

npm install

Getting started

npm run start

Development

npm run dev

Configurations (WebApp's environment variables)

1. MongoDB's hostname: MONGO_SERVICE_HOST
2. MongoDB's port: MY_MONGO_PORT

Create Application Container Image

*This section is for reference only, familiarity with Docker is required

Docker Container Image

The Dockerfile performs the following steps:

1. It is based on Node.js LTS Version 6 (Boron).
2. It then clones the Pac-Man game into the configured application directory.
3. Exposes port 8080 for the web server.
4. Starts the Node.js application using npm start.

To build the image run:

cd docker
docker build -t <registry>/<user>/pacman-nodejs-app .

You can test the image by running:

docker run -p 8000:8080 <registry>/<user>/pacman-nodejs-app

And going to http://localhost:8000/ to see if you get the Pac-Man game.

Once you're satisfied you can push the image to the container registry.

docker push <registry>/<user>/pacman-nodejs-app

Building using an s2i image
