5 Minute Tutorial

This tutorial walks you through a quick setup of ORY Hydra, a PostgreSQL instance and an exemplary User Login & Consent App based on Docker Compose. You need to have the latest Docker and Docker Compose version installed.

OAuth2 Flow with Open Source OAuth2 Server ORY Hydra

We will use the Docker Compose configuration in the ORY Hydra code base. Getting the Hydra source code is easy:

  • if you have Go 1.15+ installed: go get -d
  • if you have Git installed: git clone
  • otherwise: download the Hydra source code. and extract it somewhere

Change into the directory with the Hydra source code and run the following command to start the needed containers:

$ docker-compose -f quickstart.yml \
-f quickstart-postgres.yml \
up --build
Starting hydra_postgresd_1
Starting hydra_hydra_1

If you prefer to use MySQL as the database backend, run this command instead:

$ docker-compose -f quickstart.yml \
-f quickstart-mysql.yml \
up --build

This command makes Docker Compose start up a database server and a basic base ORY Hydra server that uses this database. If you need more details on this, please examine the scripts/ and docker-compose*.yml files.

You may also extend the command above to enable distributed tracing. The tracing UI is exposed at

$ docker-compose -f quickstart.yml \
-f quickstart-postgres.yml \
-f quickstart-tracing.yml \
up --build

Hydra provides an endpoint for Prometheus to scrape as a target. You can run the following command to start the needed containers, and status of Hydra is exposed at targets page in Prometheus http://localhost:9090/targets:

$ docker-compose -f quickstart.yml \
-f quickstart-prometheus.yml \
up --build

Let's confirm that everything is working by creating an OAuth 2.0 Client.

Note: The following commands run Hydra inside Docker. If you have the ORY Hydra CLI installed locally, you can omit docker-compose -f quickstart.yml exec /hydra in front of each command.

The OAuth 2.0 client uses port 4444 and 4445. The former is ORY Hydra's public endpoint, the latter its administrative endpoint. For more information head over to Exposing Administrative and Public API Endpoints.

Let's create the OAuth 2.0 Client:

$ docker-compose -f quickstart.yml exec hydra \
hydra clients create \
--endpoint \
--id my-client \
--secret secret \
-g client_credentials

If you get an error message about a config file not being found, you can ignore it for now:

Config file not found because "Config File ".hydra" Not Found in "[/]""
OAuth2 client my-client

Let's perform the client credentials grant:

$ docker-compose -f quickstart.yml exec hydra \
hydra token client \
--endpoint \
--client-id my-client \
--client-secret secret

Let's perform token introspection on that token. Make sure to copy the token you just got and not the dummy value.

$ docker-compose -f quickstart.yml exec hydra \
hydra token introspect \
--endpoint \
"active": true,
"client_id": "my-client",
"exp": 1527078658,
"iat": 1527075058,
"iss": "",
"sub": "my-client",
"token_type": "access_token"

Next, we will perform the OAuth 2.0 Authorization Code Grant. For that, we must first create a client that is capable of performing that grant:

$ docker-compose -f quickstart.yml exec hydra \
hydra clients create \
--endpoint \
--id auth-code-client \
--secret secret \
--grant-types authorization_code,refresh_token \
--response-types code,id_token \
--scope openid,offline \

Note that you need to add --token-endpoint-auth-method none if your clients are public (such as SPA apps and native apps) because the public clients cannot provide client secrets.

The following command starts a server that serves an example web application. The application will perform the OAuth 2.0 Authorization Code Flow using ORY Hydra. The web server runs on

$ docker-compose -f quickstart.yml exec hydra \
hydra token user \
--client-id auth-code-client \
--client-secret secret \
--endpoint \
--port 5555 \
--scope openid,offline
Setting up home route on
Setting up callback listener on
Press ctrl + c on Linux / Windows or cmd + c on OSX to end the process.
If your browser does not open automatically, navigate to:

Open the URL, log in, and authorize the application. Next, you should see at least an access token in the response. If you granted the offline scope, you will also see a refresh token. If you granted the openid scope, you will get an ID Token as well.

Great! You installed Ory Hydra, connected the CLI, created a client and completed two authentication flows! Before you continue, clean up this set up in order to avoid conflicts with other tutorials from this guide:

$ docker-compose -f quickstart.yml kill
$ docker-compose -f quickstart.yml rm -f -v
