Deployment fun

About

• get yourself a nodejs runtime
• install dependencies with npm ci
• run with npm start

Task 1

• fork repo to your own github
• create yourself a Heroku account
• initiate deployment of the repo using pipelines into newly created free Heroku app
• initiate Heroku pipelines, enable Review Apps
• create a PR which will automatically set FUN environment variable

Task 2

• initiate any kind of CI (GitHub Actions, CircleCI, ..), anything which can be connected to a GitHub
• initiate CI process - let it download dependencies, run dummy test, create deployment tarball
• utilize Ansible to initiate and deploy a machine - your local one (you can use vagrant with virtualbox, or use AWS free tier credits or any other kind of free cloud services)
• ideally, if using cloud, let the ansible deploy from the CI to the machine on e.g. deploy branch push

Task 3

• using a different CI than for Task 2, create a docker image from resulting "build" and push it into any docker container registry
• create a docker-compose.yml somewhere which will run this image, it's version being parametrized ideally by build number, or commit sha
• if you use CircleCI for this task, you can utilize cci-pingu (git)[https://github.com/salsita/cci-pingu] (npm)[https://www.npmjs.com/package/cci-pingu] node module to easily handle the deployment for you (global installation with sudo npm install -g cci-pingu)
• use certbot, to utilize Letsencrypt to generate an HTTPs certificate for the app in docker (server is required) with nginx routing it - either system nginx or (if your DNS provider is integrated) another docker image which will handle the certbot/letsencrypt tooling for you
