But you still need to define what is the dependable, the callable that you pass as a parameter to `Depends()` or `Security()`.

There are multiple tools that you can use to create those dependables, and they get integrated into OpenAPI so they are shown in the automatic docs UI, they can be used by automatically generated clients and SDKs, etc.

You can import them from `fastapi.security`:

```python
from fastapi.security import (

// (see https://docs.google.com/document/d/1F__vEKeI41P7PPUCMM9PVPYY34pyrvQI5rbTJVnS5c4)
func clusterUID(client kubernetes.Interface) (types.UID, error) {
	kubeSystem, err := client.CoreV1().Namespaces().Get(context.TODO(), "kube-system", metav1.GetOptions{})
	if err != nil {
		return "", err
	}
	return kubeSystem.UID, nil

    }

    public SmbAuthentication get(final String path) {
        if (path == null) {
            return null;
        }

        for (final Map.Entry<String, SmbAuthentication> entry : authMap.entrySet()) {
            if (path.startsWith(entry.getKey())) {

      return;
    }
    if (isPrimitiveOrNullable(invokable.getParameters().get(paramIndex))) {
      return; // there's nothing to test
    }
    @Nullable Object[] params = buildParamList(invokable, paramIndex);
    try {
      @SuppressWarnings("unchecked") // We'll get a runtime exception if the type is wrong.

                        remove(i);
                    } else if (get(i + 1).getType() == LIST_ITEM) {
                        Item item = ((ListItem) get(i + 1)).get(0);
