Ory Oathkeeper Hello world

Run the Oathkeeper server mounting the configuration and rules file.    client-credentials: enable
only the oauth2_client_credentials authenticator        It seems the default
oauth2_client_credentials scope_strategy is exact    token-introspection: enable only the
oauth2_introspection authenticatorBoth authenticators are enabled in the main config but
I'm experimenting using them one at a time enabling the desired rule$ docker run --rm \  --network hydra-oathkeeper \  --name oathkeeper-server \  -p 4455:4455 \  -p 4456:4456 \  -v $(pwd)/oathkeeper-config.yaml:/oathkeeper-config.yaml \  -v $(pwd)/AUTHENTICATOR_PER_RULE_FOLDER/rules.json:/rules.json \  oryd/oathkeeper:v0.38 \  --config /oathkeeper-config.yaml \  serve
