🎈 Lab 21 - Setting up CD for automatic deployment

⏰  Estimated time: 10-20 minutes

📚 Learning outcomes:

  • Understand how to configure a simple Continous Deployment system using Nx and GitHub actions
  • Learn how to expose custom secrets on GitHub to your CD processes

🏋️‍♀️ Steps :

  1. Add a .github/workflows/deploy.yml file

  1. Using your ci.yml config as an example, see if you can configure automated deployments from the master branch:

    Anytime we push or merge something to the master branch it:

    • builds the store and api for production
    • deploys the store and api

    We'll start you off:

    name: Deploy Website

on:
  push:
    branches:
      - master <-- workflow will run everytime we push or merge something to master
jobs:
  build:
    runs-on: ubuntu-latest
    name: Deploying apps
    steps: .... <-- ADD THE STEPS HERE

  1. Our "deploy" targets are using some secret ENV variables though. We'll need to make these available on GitHub:

    1. Go to your GitHub workshop repo
    2. Click on "Settings" at the top
    3. Then "Secrets" on the left menu bar
    4. Add values for all the variables we've been keeping in .local.env files

    GitHub secrets


  1. Then back in our deploy.yml file, let's expose these secrets to the processes (use ci.yml as an example of where to put these):

    env:
  SURGE_DOMAIN: ${{ secrets.SURGE_DOMAIN }}
  SURGE_TOKEN: ${{ secrets.SURGE_TOKEN }}
  HEROKU_API_KEY: ${{ secrets.HEROKU_API_KEY }}
  NX_API_URL: https://<your-heroku-app>.herokuapp.com

  1. Since we'll be re-deploying, we want to test if we're looking at a new version of our code:
    • Make a change to your API (maybe change the name of one of the games)
    • Make a change to your Store (maybe change the title in the header)

  1. Commit everything locally on master and then push (it's important we push to the master branch as that's where our workflow runs)

  1. You should see your new workflow start up under the "Actions" tab on your GitHub repo

  1. Once it's done, navigate to your frontend Surge deployment URL and test if you notice the new changes (the ones you made to the Store and also to the API)
