Somehow I feel this should be very simple, and I cannot seem to find a way to do it with the cirleci config.  
I have a simple task—take one value and **map** it to another based on a predefined map.  
Something like this:

```auto
buckets:
  staging:
    dashboard: staging-dashboard.example.com
    referrer: referrer-stage.example.com

```

YAML allows me to define this without problems. My issue is I cannot figure out how to use it in circleci config:

```auto
  deploy:
    executor: gcp/google
    parameters: *build_parameters
    steps:
      - attach_workspace:
          root: .
      - gcp/install
      - configure_google_sdk
      - gcp/initialize:
          gcloud-service-key: GCLOUD_SERVICE_KEY_DECODED
      - get_bucket: <<< HOW_TO_DO_THIS >>>
          environment: <<parameters.environment>>
          dashboard_type: <<parameters.dashboard_type>>
      - gcp-storage/upload:
        source_path: dist/apps/<<parameters.dashboard_type>>-admin/**
        destination_bucket: $BUCKET_NAME

```

My only solution so far has been to write a custom bash script which would map things inside code(😱) and set $BUCKET\_NAME environment variable. It seems like a massive overkill for such a simple thing, and the last thing I want is to store a mapping in some cryptic bash script.  
Any better ideas?

With Github actions [I can read](https://docs.github.com/en/actions/learn-github-actions/expressions#fromjson) from JSON files directly. Maybe something like this exists for cirleci?
