### Using Service Account Method with DVC in GitHub CI/CD Pipeline



**Content**



1. [Setup Service account and Google drive folder](#setup-service-account-and-google-drive-folder)

2. [Local Setup](#local-setup)

3. [Github Repo setup](#github-repo-setup)

4. [Github Actions](#github-actions)



### Setup Service account and Google drive folder



Go to Google cloud console -> Click APIs & Services -> Click Enable APIs and Services



![services](./assets/snap_api_services.png)



Enable Drive Labels API, Google Drive API, Google Drive Activity API



![service_api](./assets/snap_api_service_1.png)



**Setup Service account and get json key**



In this method, we can store data in a Google Drive and fetch it using service account authentication.



To create a service account, navigate to IAM & Admin in the left sidebar, and select Service Accounts.



![service_account_icon](./assets/snap_tutorial_1.png)



Click + CREATE SERVICE ACCOUNT, enter a service account name (e.g., "My DVC Project"). If you are new and don't know what permissions to choose, it's better to give owner permissions.



![owner-permission](./assets/snap_tutorial_2.png)



Add all user accounts for which you need to grant access.



![email-access](./assets/snap_tutorial_3.png)



Then click CREATE AND CONTINUE. Click DONE, and you will be returned to the overview page.



Now you can see your service account; click on it and go to the Keys tab.



![serivce-mail-id](./assets/snap_tutorial_4.png)

 

Under Add Key, select Create New Key, choose JSON, and click CREATE.



![key-creation](./assets/snap_tutorial_5.png)

 

Download the generated projectname-xxxxxx.json key file to a safe location.



Important: Store the API key in a local folder as credentials.json, but do not commit it to GitHub. If you do so, GitHub will raise a warning, and Google will be notified, revoking the credentials. 



**Google drive folder**



Create a folder in your google drive. I have created a folder with name "dvc-storage-test"



![folder](./assets/snap_dvc_storage_test.png)



Important: Give permission to the folder `anyone with the link` with **editor** access. Also share with your service account for example this is my service account mail id "[email protected]" and give editor access. The folder in should be shared to specific users (or groups) so they can use it with DVC. "Anyone with a link" is not guaranteed to work.



![permission](./assets/snap_permission_gdrive.png)



Now get the id of the folder. For example this my folder url `https://drive.google.com/drive/folders/1b4v577_NGcEuUZK3WP6vZe5G9dBTGcsG`. So this is my gdrive folder id - `1b4v577_NGcEuUZK3WP6vZe5G9dBTGcsG` 



This is the configuration url i need to add to dvc config later `gdrive://1b4v577_NGcEuUZK3WP6vZe5G9dBTGcsG` i.e gdrive://

Reference: [here](https://dvc.org/doc/user-guide/data-management/remote-storage/google-drive#url-format)



### Local Setup



Hereafter, in your local setup, you need to handle two things: the JSON file (dvcmanager-38xxxxxxx.json or any JSON with projectname-xxx.json which you downloaded as a key) and the Google Drive URL (gdrive://).



- Create a folder named data locally.



- Copy the contents from this Kaggle dataset (https://www.kaggle.com/datasets/khushikhushikhushi/dog-breed-image-dataset) into the data folder and unzip it. Remove all files that are not needed (e.g., archive.zip is not needed after unzipping).



**Tree example**



|- data



|----dataset



|--------Beagle



|--------Boxer



|-------- etc folders



|-------- etc folders



- Install dvc and dvc-gdrive



```pip install dvc dvc-gdrive```



- Run git init (if you are not in a git folder already)



- Run dvc init



- Now run `dvc remote add -d myremote gdrive:// command`. Reference [here](https://dvc.org/doc/user-guide/data-management/remote-storage/google-drive#url-format)



eg:  ```dvc remote add -d myremote gdrive://1b4v577_NGcEuUZK3WP6vZe5G9dBTGcsG````



You will see that "myremote" has been added in the .dvc file.



- Run `dvc remote modify myremote gdrive_use_service_account true`



- Run `dvc remote modify myremote gdrive_acknowledge_abuse true`



- Run ```dvc remote modify myremote --local gdrive_service_account_json_file_path path/to/file.json```. i.e For example: ```dvc remote modify --local myremote gdrive_service_account_json_file_path devcmanager-385390fe7f4f.json```



You can see similar config in your `.dvc/config` file



![dvc config](./assets/snap_config_file.png)



- Run ```dvc add data```  i.e `dvc add 



- Run ```dvc config core.autostage true``` (optional)



- Run ```dvc push -r myremote -v```



- Wait for about 10 minutes if it's around 800 MB of data for pushing; if it's in GitHub Actions, wait for 15 minutes.



Now you can check your Google Drive folder; you should see a folder named "files" like this:



![config_file](./assets/snap_files_store.png)



### Github Repo setup



- Now push this to your GitHub repository. Note that in the .dvc folder, by default, you can only push the "config" and ".gitignore" files. Don't change this; let it remain as is.



- Important: Never push the project-xxx.json file. If you do, Google will identify it and revoke the token; you'll need to set the key again.



- Add only .dvc/config, .gitignore, and data.dvc files.



- After pushing to repo, in github in your repo click on "Secrets and variables" -> "Actions" -> "Repository secret" in your GitHub repo and create a secret named "GDRIVE_CREDENTIALS_DATA" Copy the content of your project-xxx.json file (credentials.json file) into the content field.



![secrets](./assets/snap_add_secret.png)



### Github Actions



- Create a .github/workflows folder locally for setting up your GitHub Actions workflow.



- You can refer to the `dvc-pipeline.yml` file for complete content. 



Below is the code used to set up authentication and pull data inside GitHub CI/CD from Google Cloud Drive:



```

      # Note you can also directly use "GDRIVE_CREDENTIALS_DATA" as env variable and pull it

      - name: Create credentials.json

        env:

          GDRIVE_CREDENTIALS_DATA: ${{ secrets.GDRIVE_CREDENTIALS_DATA }}

        run: |

          echo $GDRIVE_CREDENTIALS_DATA > credentials_1.json



      - name: Modify DVC Remote

        run: |

          uv run dvc remote modify --local myremote gdrive_service_account_json_file_path credentials_1.json



      - name: DVC Pull Data

        run: |

          uv run dvc pull -v

```



- Now you can trigger workflow by clicking "Run workflow" in github actions



Note: I have used `uv` [package](https://pypi.org/project/uv/) in github workflow to set a virtual environment as `dvc-gdrive` is causing some issues with github server instance. So you can also run it without `uv run` before dvc commands.



![workflow-trigger](./assets/snap_run_workflow.png)



- You might see a error like this but its not a problem wait for sometime it is internally downloading files



![default_error](./assets/snap_error_gdrive.png)



- After 5 minutes(Depending on the data size) you can see successfull run



![run_success](./assets/snap_gdrive_success_run.png)
