Securing Endpoints#

Server Side Authentication#

For authentication on the BentoServer endpoint itself, a simple way to do it is via bentoml.Service’s add_asgi_middleware API. This API supports mounting any ASGI middleware to the BentoServer endpoints. And many of the middlewares built by the Python community, provides authentication or security functionality.

For example, you may apply HTTPS redirect and set trusted host URLs this way:

from starlette.middleware.httpsredirect import HTTPSRedirectMiddleware
from starlette.middleware.trustedhost import TrustedHostMiddleware

svc = bentoml.Service('my_service', runners=[...])

svc.add_asgi_middleware(TrustedHostMiddleware, allowed_hosts=['', '*'])

For JWT authentication, check out the starlette-authlib and starlette-auth-toolkit. Here’s an example with starlette-authlib:

from starlette_authlib.middleware import AuthlibMiddleware as SessionMiddleware

svc = bentoml.Service('my_service', runners=[...])

svc.add_asgi_middleware(SessionMiddleware, secret='you_secret')

Reverse Proxy#

It is more common to setup a reverse proxy server in front of a backend service, which handles rate limiting and authentication.


Add sample code for setting up a Nginx reverse proxy with BentoServer


For advanced authentication, routing policies, and service mesh, we recommend deploying Bentos with Yatai, and use Yatai’s Istio integration.
