verion:'3.7'
services:
    mongo_env:
        image: mongo:4.2.1-bionic
        ports: 
            - "27017:27017"
        volumes: 
            - $PWD/DBVOL/mongo/data:/data/db:rw
        environment: 
            MONGO_INITDB_ROOT_USERNAME: <rootuser>
            MONGO_INITDB_ROOT_PASSWORD: <mypassword>
            MONGO_INITDB_DATABASE: <mydatabase>

Answer 1

Are your sure it started successfull? Your Docker Compose has a typo in "version:3.7". correct version:

version: '3.7'
services:
mongo_env:
    image: mongo:4.2.1-bionic
    ports: 
        - "27017:27017"
    volumes: 
        - $PWD/DBVOL/mongo/data:/data/db:rw
    environment: 
        MONGO_INITDB_ROOT_USERNAME: <rootuser>
        MONGO_INITDB_ROOT_PASSWORD: <mypassword>
        MONGO_INITDB_DATABASE: <mydatabase>

Please check after starting if the container is running with

docker ps
