docker/nodejs/mongodb deployment : MongooseError [MongooseServerSelectionError]: connection timed out

update 2

I face another error, if I use path as follows, I will get "invalid volume specification" error even change path to "C:/docker-entrypoint-initdb.d/", the init-mongo.sh will not be executed, then I get "UserNotFound: Could not find user "xxxx" for db "admin"

    volumes:
      - ./init-mongo/:/docker-entrypoint-initdb.d/
      - dbdata:/data/db

so I switch to linux container, and all error message are gone.

update

I've solved my problem after disable mongodb service on local host

net stop MongoDB

and use port 27017

mongodb:
....
    ports:
      - "27017:27017"
.....

but I would like to know why I cant change port 27017 to others? I change the port because if mongodb is running on my computer (using 27017 port), I will get the following error message, thank you.

for mongodb  Cannot start service mongodb: failed to create endpoint mongodb on network server_app_network: hnsCall failed in Win32: The process cannot access the file because it is being used by another process. (0x20)

    app.listen(port, () => {
      console.log(`listening on port ${port}`);
