ImJasonH Base firebase builder on official node builder
This upgrades its npm version to 6.5

Fixes #172
Latest commit 9a4192a Feb 7, 2019


This build step invokes firebase commands that can be used in Google Cloud Build.

Arguments passed to this builder will be passed to firebase directly, allowing callers to run any firebase command.


With IAM roles

Ensure you have the following APIs enabled

  1. Cloud Resource Manager API
  2. Firebase Management API
  3. Firebase Hosting API

Add permission to the cloudbuilder

  • Open GCP IAM menu
  • Find email ending with
  • Add Cloud Build Service Account, Firebase Admin, and API Keys Admin roles to this account

With Token

Get the firebase token

This command will generate a new CI token that will be encrypted by the KMS to be used within the CLI

firebase login:ci

This will print your token on screen after login. Once done use the below command to set it to $TOKEN variable, which is used by the commands below to encrypt it.


Enable the KMS API

Click "setup" or "enable API" on

Create the secret on GCP

This step will encrypt the token via KMS. Remember to replace GENERATED_TOKEN in the text

#### create a keyring for cloudbuilder-related keys
gcloud kms keyrings create cloudbuilder --location global

#### create a key for the firebase token
gcloud kms keys create firebase-token --location global --keyring cloudbuilder --purpose encryption

#### create the encrypted token
echo -n $TOKEN | gcloud kms encrypt \
  --plaintext-file=- \
  --ciphertext-file=- \
  --location=global \
  --keyring=cloudbuilder \
  --key=firebase-token | base64

Use the encrypted key

The encrypted key (output from previous command) can now simply be used within the cloudbuilder configuration file like so:

Note that you need to specify [PROJECT_ID] directly instead of using $PROJECT_ID within secrets

- kmsKeyName: 'projects/[PROJECT_ID]/locations/global/keyRings/cloudbuilder/cryptoKeys/firebase-token'

Add permission to the cloudbuilder

  • Open GCP IAM menu
  • Find email ending with
  • Add Cloud KMS CryptoKey Decrypter role to this account
