Authentication

By default, Nessie servers run with authentication disabled and all requests are processed under the “anonymous” user identity. In Nessie clients this authentication type is known as NONE.

When a Nessie server runs as an AWS Lambda, access to its API is controlled by AWS authentication settings. In this case there is no need to configure any additional authentication in the Nessie server. In Nessie clients this authentication type is known as AWS.

When a Nessie API is exposed to clients without any external authentication layer, the server itself can be configured to authenticate clients using OpenID tokens as described in the section below. On the client side this authentication type is known as BEARER authentication.

For client-side authentication settings refer to the following pages:

OpenID Bearer Tokens

Nessie supports bearer tokens and uses OpenID Connect for validating them.

To enable bearer authentication the following configuration properties need to be set for the Nessie Server process:

  • nessie.server.authentication.enabled=true
  • quarkus.oidc.auth-server-url=<OpenID Server URL>
  • quarkus.oidc.client-id=<Client ID>

When using Nessie Docker images, the authentication options can be specified on the docker command line as environment variables, for example:

$ docker run -p 19120:19120 -e QUARKUS_OIDC_CLIENT_ID=<Client ID> -e QUARKUS_OIDC_AUTH_SERVER_URL=<OpenID Server URL>
 -e NESSIE_SERVER_AUTHENTICATION_ENABLED=true --network host projectnessie/nessie

Note the use of the host Docker network. In this example, it is assumed that the Open ID Server is available on the host network. More advanced network setup is possible, of course.
