How to deploy this application

CICD DEPLOYMENT TO HEROKU

1. Host the code on github
   • requires an account at https://github.com/
2. Connect to Travis CI to run tests on every commit
   • requires an account at https://travis-ci.org/
   • free for public GitHub repo
   • use federated login using GitHub account

     • DOCKER_PASS
     • DOCKER_USER
   • enable Travis CI to start a build at each Push and Pull Request for the repo by flipping the switch in front of your repo
3. Add Better Code Hub to pipeline to check code quality
   • seamlessly integrates with GitHub
   • use federated login using GitHub account
4. Deploy to Docker Hub
   • sign up at https://hub.docker.com/
   • Travis CI will create a docker image at the end of each pipeline build

   • Travis CI will deploy the Docker image to Heroku
   • sign up at https://signup.heroku.com/
   • create an app in Heroku
   • Go back to Travis CI and create two more variables:
     • HEROKU_API_KEY
     • HEROKU_APP_NAME
6. Commit your GitHub code to start deploying the application
