How do I switch to another serviceAccountKey.json via .firebaserc on Firebase Cloud Functions?

In my .firebaserc file, I provided two Firebase databases, one for dev and one for production:

{
  "projects": {
    "default": "db-dev",
    "production": "db-prod"
  }
}

So when I'm deploying to production, I'll just run:

firebase use production
firebase deploy --only functions

My problem is I'm also using cloud storage in one of my cloud functions, so I have two different serviceAccountKey.json files that I will use here:

const gcs = require('@google-cloud/storage')({ keyFilename: 'serviceAccountKey.json' })

My question is how do I automatically switch to another serviceAccountKey.json when I switch to another database via firebase use?

Each Firebase project will have its own Environment Configuration. The solution is to store the service account keys there.

Set the service account key for each Firebase project:

firebase use default
firebase functions:config:set admin.key="serviceAccountKey-dev.json"

firebase use production
firebase functions:config:set admin.key="serviceAccountKey-prod.json"

The environment configuration will be available via functions.config():

const functions = require('firebase-functions')
const gcs = require('@google-cloud/storage')({ 
  keyFilename: functions.config().admin.key 
})

firebase use doesn't have any way to do anything automatically like this. It simply attaches a Firebase project to your local project folder. It just manages .firebaserc for you.

You're going to have to find another way to get this done. Maybe write a script that manages both the credentials and firebase use?
