Project Template for TicTacToe

Getting started with this project template. After this you should have the project up-and-running on a Digital Ocean droplet server.

DIGITAL OCEAN

Droplet server setup:

  • Create account on DigitalOcean -- Use referral...
  • Create or use existing SSH key (no passphrase)
  • Create droplet (512mb, Ubuntu 14.04)
  • Log into droplet via ssh
ssh root@<ipaddress>

When installing docker, use curl -ssL option

To establish ssh link (selecting SSH key did not work for me):

cat ~/.ssh/id_rsa.pub | ssh root@<ipaddress> "cat >> ~/.ssh/authorized_keys"

DOCKER

Docker setup and installation

  • MacOsX/Windows - install boot2docker. Follow online instructions.
  • Remember - docker only works in boot2docker console unless you add DOCKER… environment variables.
  • Create account on docker.com, refers to docker username

GITHUB

  • fork this project - clone fork to src/ruprojects/tictactoe directory, or where ever you keep your project sources.
  • ensure you have latest node/npm
  • edit dockerbuild.sh
    • line “docker build -t gulli/tictactoe ./dist/“
    • change gulli to
  • make sure docker is running (boot2docker)
  • run
./dockerbuild
  • run
docker push <yourname>/tictactoe"

On Digital Ocean server (production)

docker run -p 80:8080 -d -e "NODE_ENV=production" <yourname>/tictactoe

Navigate to http://yourServerIpAddress and you should have yeoman landing page.
