### Default Secrets
By default, the Keboola Streamlit Docker image includes two secrets that do not require explicit specification:
## Access Storage from Data App
By default, there are two environment variables available that make it easy to access Keboola storage from your application:

- `kbc_url`: This represents the URL of the current Keboola project.
- `kbc_token`: This represents the storage token with full read-write access to Keboola Storage.
- `KBC_URL`: This represents the URL of the current Keboola project.
- `KBC_TOKEN`: This represents the storage token with full read-write access to Keboola Storage.

These secrets can be accessed within your Streamlit data app code. Here is an example of how to initialize the Keboola storage token:
These environment variables can be accessed within your Streamlit data app code. Here is an example of how to initialize the Keboola storage token:
```
token = st.secrets["kbc_storage_token"]
url = st.secrets["kbc_url"]
client = Client(url, token)
# Constants
kbc_token = os.environ.get('KBC_TOKEN')
kbc_url = os.environ.get('KBC_URL')
# Initialize Client
client = Client(kbc_url, kbc_token)
```

These variables represent the project where the application is deployed. To map data from a different project, you need to configure the appropriate secrets.

## Loading Data from Storage
To load data from the storage of a Keboola project into the app, use the [input mapping](https://help.keboola.com/transformations/mappings/#input-mapping) section.
