Can't create a postgres database with docker compose

I can’t create a postgres sql database using docker-compose.yml and an init file:
I’m using docker-compose to create my local database without success

What I have inside my docker-compose file is the following:


version: '3'

services: 
    postgresql:
        image: postgres:alpine
        container_name: postgresql
        networks:
            - des-erp
        env_file:
            - ./postgresql/database.env
        ports:
            - 5444:5444
        volumes:
            - ./postgresql/init.sql:/docker-entrypoint-initdb.d/init.sql
            - postgres_data:/var/lib/postgresql/data

So I’m using a init file as an entrypoint, this is what the sql file looks like:

CREATE DATABASE my_datbase;

The path is correct, and I’m using the command: "docker-compose up -d" in the folder the docker-compose.yml is placed.

It does create the container but can’t run the init.sql file, the error I can see in the container once created is the following:

psql:/docker-entrypoint-initdb.d/init.sql: error: could not read from input file: Is a directory.

My directory looks like the following, I’m in the "Backend" directory and this is what I can see:

ª   .gitlab-ci.yml
ª   docker-compose.yml
ª   README.md
+---postgresql
        database.env
        init.sql

I do have the postgresqlinit.sql file in the right place I believe
Im using Windows 11 btw
Any ideas?

    in volumes section you specify path to dirs not path to files

    change

    volumes:
   ./postgresql/init.sql:/docker-entrypoint-initdb.d/init.sql

    to

    volumes:
   ./postgresql:/docker-entrypoint-initdb.d

    or to

    volumes:
   <path to dir with init.sql>:/docker-entrypoint-initdb.d

    where <path to dir with init.sql> is propper local path

    Looks like the following things to be double-checked.

    ports:
    - 5444:5444

    The default port number is 5432. Please confirm if 5444 is the correct port number.

    CREATE DATABASE my_datbase;

    Please confirm if the correct name for the database is my_database.

    Actually, the container I created on my local machine seems to be working well after confirming the above information.
