Running Hydra without RethinkDB

[Jan Olszak]

Hi,

Is it possible to run hydra without Rethinkdb, just some in-memory storage? Just for development purposes.

Starting this https://github.com/ory-am/hydra/blob/master/docker-compose.yml crashes my OS after some time. 

(8GB, i7, Ubuntu 14.04).

Hail Hydra,

Jan

Yes, just do `go run main.go` that will start hydra without database or remove the DATABASE_URL in docker-compose.yml

When I remove DATABASE_URL Hydra still tries to connect to the database couple of times and then it exits 1.

Here's the modified docker-compose.yml

version: '2'

services:

  hydra:

    build:

      context: .

      dockerfile: Dockerfile-dangerous

    volumes:

      - hydravolume:/root

    ports:

      - "4444:4444"

    environment:

      - SYSTEM_SECRET=${SYSTEM_SECRET}

      - CONSENT_URL=http://${DOCKER_IP}:3000

  consent:

    environment:

      - HYDRA_URL=https://hydra:4444

      - NODE_TLS_REJECT_UNAUTHORIZED=0

    image: oryam/hydra-idp-react

    links:

      - hydra

    volumes:

      - hydravolume:/root

    ports:

      - "3000:3000"

volumes:

  hydravolume:

    driver: local

ah it might be possible that the database URL was saved to `/root/.hydra.yml`. try deleting the volume using `docker volume ls` `docker volume rm <id>` (should be something like hydra_hydravolume). make sure that you run `docker-compose kill` before.

alternatively run `docker-compose kill && docker-compose rm -f && docker-compose up`

hope that helps

It works now, thanks. I got used to data containers and forgot to cleanup volumes.

There's a mistake in the Linux example in README.md:  DOCKER_IP=tutorialpassword. Maybe it's not needed at all.

Also the example SYSTEM_SECRET is quite long for just an example.

Cheers!

I might have to fix what get's written in they .hydra.yml file.

Right now the system secret must be > 32 byte in order for AES to be 256bit strong. I will change that however to sha265(password)[:32] so passwords can be shorter
