An updated docker-compose.yaml was pushed to https://github.com/openbikesensor/portal/tree/issue_322.

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

• it often fails on the very first invocation (after clean install), consecutive invocations are not failing

docker-compose up postgres

• fails related to the different user/password for the keycloak start-dev
