docker compose up

• it's failing to access http://keycloak:8080/auth/realms/obs-dev/, it works after the realm has been configured correctly
• the URL is defined in https://github.com/openbikesensor/portal/blob/main/api/config.dev.py#L11
• there the hostname keycloak could be changed to localhost
• with the amended hostname it still fails accessing the realm, I could not figure out, where the realm obs-dev gets defined

docker-compose up keycloak

• fails with
