Docker-compose postgreSQL permission error – Nginx

I have a problem with docker-compose postgreSQL, I am working on Windows WSL 2 + Docker Desktop. When I run docker-compose on linux server it works good, but when I try to start it locally I’m getting next error:

postgres      | chmod: changing permissions of '/var/lib/postgresql/data': Operation not permitted
ngnix         | 10-listen-on-ipv6-by-default.sh: info: /etc/nginx/conf.d/default.conf is not a file or does not exist
postgres      | The files belonging to this database system will be owned by user "postgres".
postgres      | This user must also own the server process.

postgres      | The database cluster will be initialized with locale "en_US.utf8".
postgres      | The default database encoding has accordingly been set to "UTF8".

ngnix         | /docker-entrypoint.sh: Configuration complete; ready for start up
postgres exited with code 1

I tried to change permission on all project like this => chmod 777 -R project_folder

Dcoker-compose.yml:

postgresdb:
    container_name: postgres
    build:
      context: ./docker/postgres
      dockerfile: Dockerfile
    environment:
      - POSTGRES_PASSWORD=password123
    volumes:
    - ./docker/postgres/init.sql:/docker-entrypoint-initdb.d/init.sql
    - ./postgres-data:/var/lib/postgresql/data

    ports:
    - "5432:5432"

No ideas, how to resolve it. Help me please!

    So my guess here is, that since you are mounting a directory relative to the docker-compose file as "data" directory in WSL, the permission error occurs. You can try to fix these permissions (chmod, chown etc the local directory).

    You could also use "named" volumes – which should get rid of the permission problem as well.

    # docker-compose.yml

services:
  # ...
  db:
    image: postgres:latest
    volumes:
      - "dbdata:/var/lib/postgresql/data"

volumes:
  dbdata:

    My solution is to start build from Windows PowerShell, then there is no issue with permissions.
