Answers.Text: In local dev (relying on a physical `.env` file, as opposed to an injected environment on Heroku) I was still sort of "stuck" trying to short-circuit Project Config, environment vars, etc. Turns out the same advice applies—you can set `MY_GOOGLE_CLOUD_KEY_VAR` to an empty string in `.env` to basically skip Craft's processing of the key, and then set `GOOGLE_APPLICATION_CREDENTIALS` (the variable Google looks for in their own library) to a local file path, i.e. `/app/config/google.key`. Craft doesn't complain, and Google picks up the keyfile from the provided path!

Title: Unable to use credentials.json from .env file for Google Cloud Storage
ThreadText: # Unable to use credentials.json from .env file for Google Cloud Storage
  
  (Asked by: username_0 on 2021-10-27)
  
  ## Setup
  
  Craft CMS: 3.5.19.1
  PHP: 7.2.24
  
  This setup is in process of being updated to the latest version. I'm thinking the issue reported here may already be solved but I can't find any information on it. Hence I'm bringing it up.
  
  ## Issue
  
  1. Contents of the Google Cloud Storage credentials.json file were updated to a single line and put in .env under the key GOOGLE\_APPLICATION\_CREDENTIALS. As seen below:
  
  ```
  GOOGLE_APPLICATION_CREDENTIALS='{"type": "service_account","project_id": "my-project","private_key_id": "000000000000000","private_key": "-----BEGIN PRIVATE KEY-----\n00000000000000000\n-----END PRIVATE KEY-----\n","client_email": "my-service@my-project.iam.gserviceaccount.com","client_id": "000000000000000","auth_uri": "https://accounts.google.com/o/oauth2/auth","token_uri": "https://accounts.google.com/o/oauth2/token","auth_provider_x509_cert_url": "https://www.googleapis.com/oauth2/v1/certs","client_x509_cert_url": "https://www.googleapis.com/my/path/my-service%40my-project.iam.gserviceaccount.com"}'
  
  ```
  
  2. This was good enough to refresh the bucket and saving successfully but upon attempting to upload new files it would result in the error below:
  
  ```
  {
      "error": {
          "code": 403,
          "message": "Provided scope(s) are not authorized",
          "errors": [
              {
                  "message": "Provided scope(s) are not authorized",
                  "domain": "global",
                  "reason": "forbidden"
              }
          ]
      }
  }
  
  ```
  
  4. I ended up copying the contents directly through the UI as the [documentation in github seems to indicate](https://github.com/craftcms/google-cloud) and it worked fine but this of course puts the keys into the project config files which now can't be committed to the repo.

  In retrospect, this was actually fairly obvious but I guess the introduction of configuration files and their use of .env variables confused me.
  
  If you want to use json file to authenticate to Google Cloud. Then all you need to do is:
  
  1. Secure the json in your server (place it somewhere the world won't be able to access it).
  2. Add the path to your json in your `.env` file under the variable `GOOGLE_APPLICATION_CREDENTIALS`
  3. Configure your volume to use Google but leave the field ***Contents of access key file*** EMPTY. This value will be picked up automatically from the `.env`.
  4. Click **Refresh** to confirm it sees the buckets and you're done.
  
  This way, your json file will be secure and out of your repo.
