Hvordan kører man MongoDB og Mongo-express med docker-compose?

det virker på min mac. Hvis du sletter docker-compose containere og genopbygger, vil det måske virke. Jeg tilføjede mine filer. Kun jeg ændrede mongo-express port.

.env

MONGO_ROOT_USER=devroot
MONGO_ROOT_PASSWORD=devroot
MONGOEXPRESS_LOGIN=dev
MONGOEXPRESS_PASSWORD=dev

docker-compose.yml

version: '3'

services:
    mongo:
        image: mongo
        environment:
            - MONGO_INITDB_ROOT_USERNAME=${MONGO_ROOT_USER}
            - MONGO_INITDB_ROOT_PASSWORD=${MONGO_ROOT_PASSWORD}
            - MONGO_INITDB_DATABASE=project
    mongo-express:
        image: mongo-express
        environment:
            - ME_CONFIG_MONGODB_SERVER=mongo
            - ME_CONFIG_MONGODB_PORT=27017
            - ME_CONFIG_MONGODB_ENABLE_ADMIN=false
            - ME_CONFIG_MONGODB_AUTH_DATABASE=admin
            - ME_CONFIG_MONGODB_AUTH_USERNAME=${MONGO_ROOT_USER}
            - ME_CONFIG_MONGODB_AUTH_PASSWORD=${MONGO_ROOT_PASSWORD}
            - ME_CONFIG_BASICAUTH_USERNAME=${MONGOEXPRESS_LOGIN}
            - ME_CONFIG_BASICAUTH_PASSWORD=${MONGOEXPRESS_PASSWORD}
        depends_on:
            - mongo
        ports:
          - "8888:8081"
