## Types and validation

These environment variables can only handle text strings, as they are external to Python and have to be compatible with other programs and the rest of the system (and even with different operating systems, as Linux, Windows, macOS).

    Object[] params = new Object[sig.size()];
    params[0] = firstParam;
    if (params.length > 1) {
      params[1] = "";
      if (params.length > 2) {
        // fill in the rest of the array with arbitrary instances
        for (int i = 2; i < params.length; i++) {
          params[i] = ArbitraryInstances.get(sig.get(i));
        }
      }
    }
    return params;
  }

Mithilfe des Zertifikats entscheiden der Client und der TLS-Terminierungsproxy dann, **wie der Rest der TCP-Kommunikation verschlüsselt werden soll**. Damit ist der **TLS-Handshake** abgeschlossen.

    This is where we'll put the `requirements.txt` file and the `app` directory.

3. Copy the file with the requirements to the `/code` directory.

    Copy **only** the file with the requirements first, not the rest of the code.

    As this file **doesn't change often**, Docker will detect it and use the **cache** for this step, enabling the cache for the next step too.

4. Install the package dependencies in the requirements file.

/// tip

This is a somewhat advanced technique, and in most of the cases you won't really need it, as you can raise exceptions (including `HTTPException`) from inside of the rest of your application code, for example, in the *path operation function*.

But it's there for you if you need it. 🤓

In addition to this conversion, `Ingress` requires writing the address it can be reached at in status. This is done by the Ingress Status controller.

MINIO_IDENTITY_OPENID_KEYCLOAK_ADMIN_URL    (string)    Specify Keycloak 'admin' REST API endpoint e.g. http://localhost:8080/auth/admin/
MINIO_IDENTITY_OPENID_REDIRECT_URI_DYNAMIC  (on|off)    Enable 'Host' header based dynamic redirect URI (default: 'off')
