GitHub Action for interacting with Firebase

GitHub Actions for Firebase

This Action for firebase-tools enables arbitrary actions with the firebase command-line client.

If you want a more flexible implementation, an early version of a rewrite is available here: setup-firebase that allows you to choose node and java version and run more than one command.

Inputs

• args - Required. This is the arguments you want to use for the firebase cli

Outputs

* response - The full response from the firebase command current run (Will most likely require a grep to get what you want, like URLS)

Response has been removed for now as it caused loads of issues in the bash script

Environment variables

• GCP_SA_KEY - Required if FIREBASE_TOKEN is not set. A normal service account key (json format) or a base64 encoded service account key with the needed permissions for what you are trying to deploy/update.

  • Since the service account is using the App Engine default service account in the deploy process, it also needs the Service Account User role.
  • If deploying functions, you would also need the Cloud Functions Developer role.
    • If the deploy has scheduled functions, include the Cloud Scheduler Admin role.
    • If the deploy requires access to secrets, include the Secret Manager Viewer role.
    • If updating Firestore Rules, include the Firebase Rules Admin role.
  • If updating Firestore Indexes, include the Cloud Datastore Index Admin role.
  • If deplying Hosting files, include the Firebase Hosting Admin role.
  • For more details: https://firebase.google.com/docs/hosting/github-integration

• FIREBASE_TOKEN - Required if GCP_SA_KEY is not set. This method will soon be deprecated, use GCP_SA_KEY instead. The token to use for authentication. This token can be aquired through the firebase login:ci command.

• PROJECT_ID - Optional. To specify a specific project to use for all commands. Not required if you specify a project in your .firebaserc file. If you use this, you need to give Viewer permission roles to your service account otherwise the action will fail with authentication errors.

• PROJECT_PATH - Optional. The path to the folder containing firebase.json if it doesn't exist at the root of your repository. e.g. ./my-app.

• CONFIG_VALUES - Optional. The configuration values for Firebase function that would normally be set with firebase functions:config:set [value]. Example: CONFIG_VALUES: stripe.secret_key=SECRET_KEY zapier.secret_key=SECRET_KEY.

Example

To authenticate with Firebase, and deploy to Firebase Hosting:

name: Build and Deploy
on:
  push:
    branches:
      - master

jobs:
  build:
    name: Build
    runs-on: ubuntu-latest
    steps:
      - name: Checkout Repo
        uses: actions/checkout@master
      - name: Install Dependencies
        run: npm install
      - name: Build
        run: npm run build-prod
      - name: Archive Production Artifact
        uses: actions/upload-artifact@master
        with:
          name: dist
          path: dist
  deploy:
    name: Deploy
    needs: build
    runs-on: ubuntu-latest
    steps:
      - name: Checkout Repo
        uses: actions/checkout@master
      - name: Download Artifact
        uses: actions/download-artifact@master
        with:
          name: dist
          path: dist
      - name: Deploy to Firebase
        uses: w9jds/firebase-action@master
        with:
          args: deploy --only hosting
        env:
          FIREBASE_TOKEN: ${{ secrets.FIREBASE_TOKEN }}

Alternatively:

        env:
          GCP_SA_KEY: ${{ secrets.GCP_SA_KEY }}

If you have multiple hosting environments you can specify which one in the args line. e.g. args: deploy --only hosting:[environment name]

If you want to add a message to a deployment (e.g. the Git commit message) you need to take extra care and escape the quotes or the YAML breaks.

        with:
          args: deploy --message \"${{ github.event.head_commit.message }}\"

Alternate versions

Starting with version v2.1.2 each version release will point to a versioned docker image allowing for hardening our pipeline (so things don't break when I do something dump). On top of this, you can also point to a master version if you would like to test out what might not be deployed into a release yet by using something like this:

  name: Deploy to Firebase
  uses: docker://w9jds/firebase-action:master
  with:
    args: deploy --only hosting
  env:
    FIREBASE_TOKEN: ${{ secrets.FIREBASE_TOKEN }}

Recommendation

If you decide to do seperate jobs for build and deployment (which is probably advisable), then make sure to clone your repo as the Firebase-cli requires the firebase repo to deploy (specifically the firebase.json)
