Firebase Multisite Hosting

Posted: 5/20/2022

This tutorial will focus on a very easy solution to having multiple web projects hosted under the same domain.

Firebase limits a single domain for all of your projects. Once you have associated this domain you not be able to use it again for any other project. For example we would like to use lessons.ajonp.com but since we are using ajonp-ajonp-com for ajonp.com domain we are unable to use this.

We also wanted to mention that the video may not match exactly what is in the lesson7 repo, we are sorry about that, initially we were going to use two projects with a single domain. Please pull the repo directly and these steps should help you get to a finished setup quickly.

Steps

Switching Firebase Plans
Create 4 Firebase Hosting Sites
Example Multiple Hugo Themes deploying to Firebase Multisite
Example Angular Project with Multiple projects deploying to Firebase Multisite
Google Cloud Builder - Trigger

Firebase Pricing Plans

New Project

If you have just created a new project you will need to upgrade in order to use Multisite hosting.

Firebase Pricing is ever changing, so make sure to check on this.

Hosting Free limit on the Blaze plan

Create 4 Firebase Hosting Sites

You can name these whatever fits your project, if you using ajonp* you will probably have issues as we am already using those.

Example for your site:

mysite
mysite-admin
mysite-amp
mysite-app

Example Multiple Hugo Themes deploying to Firebase Multisite

You don’t need to install anything if you just deploy to Google Cloud. In this lesson reference Cloud Build Also see https://ajonp.com/lessons/google-cloud-repositories-ci-cd for more details on CI/CD.

Once you clone https://github.com/AJONPLLC/lesson-7-firebase-multisite-hosting you can run it locally, but you must build out all of the sites before doing this.

Remove git reference

Please remove the reference to AJONPLLC, then you can add any git repo you would like.

git remote rm origin

Add new reference

Create a new github site (or Gitlab or Google Cloud or…)

Then add the new repo back to your site using this command, replace ajonp/a-sample-repo.git with yours.

git remote add origin https://github.com/ajonp/a-sample-repo.git git push -u origin master

Steps for building hugo sites

Git Submodule commands, make sure you have Git CLI.

git submodule init git submodule update --recursive --remote

This will update to the latest remote builds for ajonp.com, including both the content and themes that we host publicly

Hugo commands, make sure you have the Hugo CLI installed.

hugo -d dist/ajonp -v -t ajonp-hugo-ionic --config config.toml,production-config.toml hugo -d dist/ajonp-amp -v -t ajonp-hugo-amp --config config.toml,production-config.toml

Example Angular Project with Multiple projects deploying to Firebase Multisite

Steps for building Angular sites

NPM commands, make sure you have Node Js installed.

npm install

Angular commands, make sure you have the Angular CLI installed.

ng build --prod --project ajonp-admin ng build --prod --project ajonp-app

Serve locally using firebase, make sure you have Firebase CLI

firebase serve

Google Cloud Builder - Trigger

Please add a trigger to your repository reference Firebase CI/CD lesson for more details.

Cloud Build

Now after having tried all of the manual build steps out, you really don’t need any of them. You can run all of this in the cloud by setting up the commit trigger from above.

cloudbuild.yaml

steps:
  # Pull in the required submodules for our themes and content
  - name: gcr.io/cloud-builders/git
    args: ['submodule', 'init']
  - name: gcr.io/cloud-builders/git
    args: ['submodule', 'update', '--recursive', '--remote']
  # Install all of our dependencies
  - name: 'gcr.io/cloud-builders/npm'
    args: ['install']
  # Build the hugo image
  - name: 'gcr.io/cloud-builders/docker'
    args: ['build', '-t', 'gcr.io/$PROJECT_ID/hugo', './dockerfiles/hugo']
  # Build ajonp-hugo-ionic -> dist/ajonp
  - name: 'gcr.io/$PROJECT_ID/hugo'
    args:
      [
        'hugo',
        '-d',
        'dist/ajonp',
        '-v',
        '-t',
        'ajonp-hugo-ionic',
        '--config',
        'config.toml,production-config.toml'
      ]
  # Build ajonp-hugo-amp -> dist/ajonp-amp
  - name: 'gcr.io/$PROJECT_ID/hugo'
    args:
      [
        'hugo',
        '-d',
        'dist/ajonp-amp',
        '-v',
        '-t',
        'ajonp-hugo-amp',
        '--config',
        'config.toml,production-config.toml'
      ]
  # Build the hugo image
  - name: 'gcr.io/cloud-builders/docker'
    args: ['build', '-t', 'gcr.io/$PROJECT_ID/ng:latest', './dockerfiles/ng']
  # Build ajonp-admin -> dist/ajonp-admin
  - name: 'gcr.io/$PROJECT_ID/ng:latest'
    args: ['build', '--prod', '--project', 'ajonp-admin']
  # Build ajonp-admin -> dist/ajonp-app
  - name: 'gcr.io/$PROJECT_ID/ng:latest'
    args: ['build', '--prod', '--project', 'ajonp-app']
  # Build the firebase image
  - name: 'gcr.io/cloud-builders/docker'
    args: ['build', '-t', 'gcr.io/$PROJECT_ID/firebase', './dockerfiles/firebase']
  # Deploy to firebase
  - name: 'gcr.io/$PROJECT_ID/firebase'
    args: ['deploy', '--token', '${_FIREBASE_TOKEN}']
# Optionally you can keep the build images
# images: ['gcr.io/$PROJECT_ID/hugo', 'gcr.io/$PROJECT_ID/firebase']

Cloud Build locally

If you would like to debug locally please make sure you read Building and debugging locally. This will require that you have Docker installed locally.

Install necessary components

Install docker-credential-gcr

Configure Docker

Check to see if version is working

In the root directory of your project, you can then run this command (don’t forget the ”.” as this tells Cloudbuild to use the current directory)

You will notice that this output matches what happens in the cloud when Google Cloud Build executes
