### Override the `HTTPException` error handler { #override-the-httpexception-error-handler }

The same way, you can override the `HTTPException` handler.

For example, you could want to return a plain text response instead of JSON for these errors:

{* ../../docs_src/handling_errors/tutorial004.py hl[3:4,9:11,22] *}

/// note | Technical Details

### `HTMLResponse` { #htmlresponse }

Takes some text or bytes and returns an HTML response, as you read above.

### `PlainTextResponse` { #plaintextresponse }

Takes some text or bytes and returns a plain text response.

{* ../../docs_src/custom_response/tutorial005.py hl[2,7,9] *}

### `JSONResponse` { #jsonresponse }

Takes some data and returns an `application/json` encoded response.

### `HTMLResponse`

Toma algún texto o bytes y devuelve un response HTML, como leíste arriba.

### `PlainTextResponse`

Toma algún texto o bytes y devuelve un response de texto plano.

{* ../../docs_src/custom_response/tutorial005.py hl[2,7,9] *}

### `JSONResponse`

Toma algunos datos y devuelve un response codificado como `application/json`.

### Deploy a more secure control plane with kubeadm

A new alpha feature allows running the kubeadm control plane components as non-root users. This is a long requested security measure in kubeadm. To try it you must enable the kubeadm-specific `RootlessControlPlane` feature gate. When you deploy a cluster using this alpha feature, your control plane runs with lower privileges.
