Deploying a firebase function from Bitbucket pipelines

README.md

Deploying functions from Bitbucket Pipelines

It's quite easy and the same process applies to all Firebase features with minor changes.

Acquire a deployment token

In order to deploy you'll need a deployment token (I named it FIREBASE_TOKEN) and it can be acquired by using the following command

firebase login:ci

Add it to your pipeline's environment variables or to your team's environment variables if you want to use it among multiple repositories.

When you have many functions on the same repository

You can define the function to get deployed using --only functions:addMessage as defined on the Firebase documentation.

The boring part is that you should find out which function got changed to deploy just it, what you can do using git.

The supported node versions

bitbucket-pipelines.yml

# using the available node version at Google Cloud Function

  default:
    - step:
        name: Test function
        caches:
          - functions-npm
        script:
        - export PATH=$PATH:$BITBUCKET_CLONE_DIR/functions/node_modules/.bin
        - cd functions

        # - npm test

          script:
          - export PATH=$PATH:$BITBUCKET_CLONE_DIR/functions/node_modules/.bin
          - cd functions
          - npm install
          - npm install firebase-tools
          - firebase deploy
              --only functions
              --non-interactive
              --token=$FIREBASE_TOKEN
              -m "Deploying $BITBUCKET_COMMIT (CI/CD)"
definitions:
  caches:
    functions-npm: $BITBUCKET_CLONE_DIR/functions/node_modules

Trying to execute this pipeline throws the following error

Error: HTTP Error: 401, Request had invalid authentication credentials. Expected OAuth 2 access token, login cookie or other valid authentication credential.

can you give me a hand with this?

How to define other project to deploy?

Hello @Donkijote,

I'd guess that's probably because of the node version. It won't allow the installation of the lastest firebase-tools, and probably the one available to node@6.11 doesn't connect to the firebase API anymore.

Yeap, as for June 8th 2020 the support for node 8.x was dropped (imagine for 6.x 😅)

I updated the script to use the latest node version supported by firebase. As of today, the latest stable is v12. You can use v14, but it is still in beta.

Hello @alexander0205,

You might want to have a look at the firebase use command. It sets the default project to be used. You'll need to add a line invoking it before the firebase deploy on at line 25.
