Configuring and Running ORY Oathkeeper
ORY Oathkeeper has two servers that run on separate ports:
- The api server: This server is responsible for exposing the management REST API.
- The proxy server: This server is responsible for evaluating access requests and forwarding them to the backend.
For detailed documentation on the two servers, run
oathkeeper help serve api and
oathkeeper help serve proxy.
ORY Oathkeeper supports two types of storage adapters:
- In-memory: This adapter does not work with more than one instance ("cluster") and any state is lost after restarting the instance.
- SQL: This adapter works with more than one instance and state is not lost after restarts.
The SQL adapter supports two DBMS: PostgreSQL 9.6+ and MySQL 5.7+. Please note that older MySQL versions have issues with the database schema. For more information go here.
ORY Oathkeeper supports various authentication, authorization, and credential strategies. Depending on what strategies you want to use, you will have to configure more services (e.g. ORY Hydra or ORY Keto). In this tutorial, we will set up ORY Oathkeeper without any of the other services. Please refer to the authenticator, authorizer, and credentials issuer documentation to see what you need to configure in order to get the strategies you need.
This guide will:
- Download and run a PostgreSQL container in Docker.
- Download and run ORY Oathkeeper using Docker.
Create a Network
Before we can start, a network must be created which we will attach all our Docker containers to. That way, the containers can talk to one another.
$ docker network create oathkeeperguide
Start the PostgreSQL Container
For the purpose of this tutorial, we will use PostgreSQL as a database. As you probably already know, don't run databases in Docker in production! For the sake of this tutorial however, let's use Docker to quickly deploy the database.
$ docker run \ --network oathkeeperguide \ --name ory-oathkeeper-example--postgres \ -e POSTGRES_USER=oathkeeper \ -e POSTGRES_PASSWORD=secret \ -e POSTGRES_DB=oathkeeper \ -d postgres:9.6
This command wil start a postgres instance with name
ory-oathkeeper-example--postgres, set up a database called
and create a user
oathkeeper with password
Run the ORY Oathkeeper API Proxy
# The database url points us at the postgres instance. This could also be an ephermal in-memory database (`export DATABASE_URL=memory`) # or a MySQL URI. $ export DATABASE_URL=postgres://oathkeeper:secret@ory-oathkeeper-example--postgres:5432/oathkeeper?sslmode=disable # This pulls the latest image from Docker Hub $ docker pull oryd/oathkeeper:v1.0.0-beta.5 # ORY Oathkeeper does not do magic, it requires conscious decisions, for example running SQL migrations which is required # when installing a new version of ORY Oathkeeper, or upgrading an existing installation. # It is the equivalent to `oathkeeper migrate sql postgres://oathkeeper:secret@ory-oathkeeper-example--postgres:5432/oathkeeper?sslmode=disable` $ docker run -it --rm \ --network oathkeeperguide \ oryd/oathkeeper:v1.0.0-beta.5 \ migrate sql $DATABASE_URL Applying `client` SQL migrations... [...] Migration successful! # Next, let's run the API server! # # Please make sure to use your own secret. $ docker run -d \ --name ory-oathkeeper-example--oathkeeper-api \ --network oathkeeperguide \ -p 4456:4456 \ -e DATABASE_URL=$DATABASE_URL \ -e PORT=4456 \ -e CREDENTIALS_ISSUER_ID_TOKEN_HS256_SECRET=changemechangemechangemechangemedo \ oryd/oathkeeper:v1.0.0-beta.5 \ serve api # And the proxy server too - take not that we need to link the proxy serve with the API server! # # Please make sure to use your own secret. $ docker run -d \ --name ory-oathkeeper-example--oathkeeper-proxy \ --network oathkeeperguide \ -p 4455:4455 \ -e OATHKEEPER_API_URL=http://ory-oathkeeper-example--oathkeeper-api:4456/ \ -e PORT=4455 \ -e CREDENTIALS_ISSUER_ID_TOKEN_HS256_SECRET=changemechangemechangemechangeme \ oryd/oathkeeper:v1.0.0-beta.5 \ serve proxy
Great, both the API and the proxy server are running now! Make sure to check the logs and see if there were any errors or issues before going to the next steps:
$ docker logs ory-oathkeeper-example--oathkeeper-api $ docker logs ory-oathkeeper-example--oathkeeper-proxy
Creating your first access rule
Sorry, this section is still work in progress.
- Create the rule using
oathkeeper rules import- need to figure out how to add the file to docker to make this work.
- Have a rule that works immediately, e.g. protect an Oathkeeper API URL using the Oathkeeper proxy
- Have two CURL requests where one fails and one passes. Explain why that happens
- Clean up
