Can't loging as admin using docker

[tiagobatistacolab]

Describe the bug
I'm not able to login with the admin user in a docker installation.

Whenever I type the credentials I get the message "invalid credentials"

both server containers and frontend containers works normaly. I can, for example, create a new user from frontend. But without login as admin, I get my hands tied 😢

here is my docker-compose.yml

version: '3.5'

x-environment-vars: &environment-vars
  POSTGRES_HOST: postgres
  DATABASE_URL: postgresql://open_event_user:opev_pass@postgres:5432/open_event
  REDIS_URL: redis://redis:6379/0
  ADMIN_EMAIL: "@{tiago@....}"
  ADMIN_PASSWORD: "@{c...}"

x-defaults: &defaults
  image: eventyay/open-event-server:development
  restart: unless-stopped
  env_file:
    - .env
  environment:
    <<: *environment-vars
  depends_on:
    - postgres
    - redis
  volumes:
   - ./static:/data/app/static
    - ./generated:/data/app/generated # Workaround for #6155

services:

  postgres:
    image: postgis/postgis:12-3.0-alpine
    container_name: opev-postgres
    restart: unless-stopped
    volumes:
      - pg:/var/lib/postgresql/data

environment:
      POSTGRES_USER: open_event_user
      POSTGRES_PASSWORD: opev_pass
      POSTGRES_DB: open_event

  redis:
    image: redis:3-alpine
    container_name: opev-redis
    restart: unless-stopped
    command: redis-server
    volumes:
      - rd:/var/lib/redis/data

  web:
    <<: *defaults
container_name: opev-web
    ports:

  celery:
    <<: *defaults

    depends_on:

    environment:
      <<: *environment-vars
      C_FORCE_ROOT: "true"
    command: celery

volumes:
    pg:
    rd:

and here my .env

#DATABASE_URL=postgresql:///oevent

# If using fast docker test DB, uncomment following line

#APP_CONFIG=config.DevelopmentConfig

POSTGRES_DB=open_event

FLASK_APP=app.instance

Same here, I want to test Open Event and can't do anything because there is no admin login.
@tiagobatistacolab Did you find a solution?

I managed to find the default admin username / password, though I don't see it anywhere in the documentation.
It's open_event_test_user@fossasia.org / fossasia
