FIREBASE_TOKEN migration

Firebase CLI Tools announced depreciatiation of token authentication in favor of Service Account (source).

This means that actions configured with token parameter will stop working.

Those guides are prepared to make migration from token to Service Account as easy as possible. They both lead to the same but they differ with level of details. Choose what suits you best.

Guide 1 - TLDR;

1. Follow instructions described in the official documentation until reaching point 3 (create and download private JSON key).
2. Create a new Secret in Github (Settings > Secrets > Actions) with value of content of file generated in the previous point (in sample below, the name of this secret is CREDENTIAL_FILE_CONTENT).
3. Update configuration of Github Action:
   1. remove token parameter
   2. add serviceCredentialsFileContent with value of secret created in point 2.

E.g.

    - name: upload artifact to Firebase App Distribution
      uses: wzieba/Firebase-Distribution-Github-Action@v1
      with:
        appId: ${{secrets.FIREBASE_APP_ID}}
-       token: ${{secrets.FIREBASE_TOKEN}}
+       serviceCredentialsFileContent: ${{ secrets.CREDENTIAL_FILE_CONTENT }}
        groups: testers
        file: app/build/outputs/apk/release/app-release-unsigned.apk

Guide 2 - the same but with screenshots

1. Open Google Cloud Console
2. Select your project

3. Click on Create Service Account

4. Enter some account name, press Create and continue

5. Select Firebase App Distribution Admin in Role input and click Done

6. Then, on the list of accounts find your newly created service account. Click on 3-dots menu and click on Manage keys

7. Click on Add key and then Create new key

8. Select type JSON and click Create

9. After that, the file should be downloaded to your disk. Open the file, and copy its content.
10. Go to Github > your repository > Settings > Secrets > Actions
11. Create a new secret. Name it e.g. CREDENTIAL_FILE_CONTENT. The value of the secret is the content from the file copied in point 9.
12. Save the secret. Important! Remember about removing fetched file from your disk or store it in some secure place.
13. Update configuration of your Github Actions. E.g.

E.g.

    - name: upload artifact to Firebase App Distribution
      uses: wzieba/Firebase-Distribution-Github-Action@v1
      with:
        appId: ${{secrets.FIREBASE_APP_ID}}
-       token: ${{secrets.FIREBASE_TOKEN}}
+       serviceCredentialsFileContent: ${{ secrets.CREDENTIAL_FILE_CONTENT }}
        groups: testers
        file: app/build/outputs/apk/release/app-release-unsigned.apk
