I want to create a MongoDB database and populate it with a number of collections on the start up of a docker container using docker-compose

问题

I have a number of collections with schema validation rules that I would like to use to populate a database on the startup of a docker container using the docker-compose up --build command.

Since there are so many collections, I have separated the collections into different js files for hopefully clean directory structure and code organization and readability. Each js file exports a variable of the form

export const CollectionDeps = ["NameOfCollection", obj];

where the object is the json schema validator. E.g.,

obj = {
  validator: {
    $jsonSchema: {
      bsonType: "object",
      required: [...], // required fields
      properties: {
        Field1: { ... },
        Field2: { ... },
        Field3: { ... }
      }
    }
  }
}

I am running on Ubuntu 18.04 and using the official mongo image from DockerHub (https://hub.docker.com/_/mongo). I have tried to follow the method that someone proposed in this question (https://stackoverflow.com/a/54064268/3716628) but it hasn't accomplished what I want.

Directory structure

                    | - collection1a.js
                    | - collection1b.js
               | -- Collection2
                    | - collection2a.js
          mongo-init.js

docker-compose.yml

version: '3.7'

services:
  mongodb:
    image: mongo
    container_name: mongodb
    restart: always
    environment:
      MONGO_INITDB_ROOT_USERNAME: root
      MONGO_INITDB_ROOT_PASSWORD: example
      MONGO_INITDB_DATABASE: my_test_db
    ports:

    volumes:
      - ./ssl-data/server.pem:/etc/ssl/server.pem
      - ./persistent-storage-mongo:/data/db
      - ./scripts/collections:/docker-entrypoint-initdb.d/collections
      - ./scripts/mongo-init.js:/docker-entrypoint-initdb.d/mongo-init.js:ro
    command:
      - --sslMode=requireSSL
      - --sslPEMKeyFile=/etc/ssl/server.pem
      - --sslPEMKeyPassword=somepassword
      - --sslAllowInvalidCertificates
      - --sslAllowInvalidHostnames

collections/CollectionX/collectionXn.js

export const CollectionXn = ["CollectionXn", obj] // see above for what obj is

mongo-init.js

db.auth('root', 'example');
db = db.getSiblingDB('my_test_db')

// Collection1 schemas
import Collection1a from 'collections/Collection1/collection1a.js'
import Collection1b from 'collections/Collection1/collection1b.js'
db.createCollection(Collection1a[0], Collection1a[1]);
db.createCollection(Collection1b[0], Collection1b[1]);
// Collection2 schemas
import Collection2a from 'collections/Collection2/collection2a.js'
db.createCollection(Collection2a[0], Collection2a[1]);

The container starts up after I run docker-compose up --build -d mongodb and I can connect to it and access the mongodb using ssl as I have configured, but the database (my_test_db) and collections have not been created.

Does anyone have any suggestions for where I'm going wrong?
