gistfile1.txt

1. Install heroku
  reference: https://toolbelt.heroku.com 
  wget -O- https://toolbelt.heroku.com/install-ubuntu.sh | sh

2. create a heroku app
  heroku login
  heroku apps:create foobar
  
3. Set a Meteor buildpack for your Heroku instance
  reference: https://elements.heroku.com/search/buildpacks?q=meteor
  heroku buildpacks:set https://github.com/AdmitHub/meteor-buildpack-horse.git

4. Create a new mLab instance (As of February 29, 2016, MongoLab has changed their name to mLab)
  heroku addons:create mongolab:sandbox (sandbox: free tier)
  
5. Get your MongoLab URI 
  heroku config | grep MONGOLAB_URI
  heroku config | grep MONGODB_URI
  
6. Set the configurations of your Meteor app running on Heroku
  heroku config:add MONGO_URL=<MONGOLAB_URI value>
  heroku config:add ROOT_URL=<APP_URL>

7. Check your remotes to ensure heroku is there
  git remote -v
  
8. Deploy app
  git push heroku master
  git push heroku <branch>:master (<branch> is which needed to deploy)

Bonus:
1. Work around to redeploy without modifing 
  git commit --allow-empty -m "empty commit"
  git push heroku master
2. Check log
  heroku logs --tail
3. Multiple Heroku apps in one folder
  // Add a suffix to Heroku commands
  --app yourAppName
4. Using external MongoDB service
  mongodb://<dbUser>:<dbPassword>@<service>.com:<port>/<databaseName>
  developments:
    MONGO_URL=mongodb://<dbUser>:<dbPassword>@<service>.com:<port>/<databaseName> meteor
  // In server
    process.env.MONGO_URL=mongodb://<dbUser>:<dbPassword>@<service>.com:<port>/<databaseName>
5. Use setiings.json
  // For development
  meteor --settings settings.json
  // For Heroku
  heroku config:add METEOR_SETTINGS="$(cat settings.json)"
  // Please remember to .gitignore it if you're using a public repository
