Cannot create a mongo database with docker - mongodb

Question

I'm having trouble creating a mongo database using the docker-compose command. Docker desktop tells me that everything is up and running including the db, but all I get is the standard 'admin, config, local' not the db I want to create. Here's my docker-compose.yaml
version: '3'
services:
app:
build: ./
entrypoint: ./.docker/entrypoint.sh
ports:
- 3000:3000
volumes:
- .:/home/node/app
depends_on:
- db
db:
image: mongo:4.4.4
restart: always
volumes:
- ./.docker/dbdata:/data/db
- ./.docker/mongo:/docker-entrypoint-initdb.d
environment:
- MONGO_INITDB_ROOT_USERNAME=root
- MONGO_INITDB_ROOT_PASSWORD=root
- MONGO_INITDB_DATABASE=nest
mongo-express:
image: mongo-express
restart: always
ports:
- 8081:8081
environment:
- ME_CONFIG_MONGODB_SERVER=db
- ME_CONFIG_MONGODB_AUTH_USERNAME=root
- ME_CONFIG_MONGODB_AUTH_PASSWORD=root
- ME_CONFIG_MONGODB_ADMINUSERNAME=root
- ME_CONFIG_MONGODB_ADMINPASSWORD=root
depends_on:
- db
my init.js inside .docker/mongo
db.routes.insertMany([
{
_id: "1",
title: "Primeiro",
startPosition: {lat: -15.82594, lng: -47.92923},
endPosition: {lat: -15.82942, lng: -47.92765},
},
{
_id: "2",
title: "Segundo",
startPosition: {lat: -15.82449, lng: -47.92756},
endPosition: {lat: -15.82776, lng: -47.92621},
},
{
_id: "3",
title: "Terceiro",
startPosition: {lat: -15.82331, lng: -47.92588},
endPosition: {lat: -15.82758, lng: -47.92532},
}
]);
and my dockerfile
FROM node:14.18.1-alpine
RUN apk add --no-cache bash
RUN npm install -g #nestjs/cli
USER node
WORKDIR /home/node/app
and this is the 'error' log I get from docker when I run the nest container with mongodb, nest app and mongo express(there is actually a lot more but SO keeps thinking that it is spam for some reason.
about to fork child process, waiting until server is ready for connections.
Successfully added user: {
"user" : "root",
"roles" : [
{
"role" : "root",
"db" : "admin"
}
]
}

this is what running docker-compose ps shows

this what my docker desktop shows

Answer 1

The MongoDB container only creates a database if no database already exists. You probably already have one, which is why a new database isn't created and your initialization script isn't run.
Delete the contents of ./.docker/dbdata on the host. Then start the containers with docker-compose and Mongo should create your database for you.
