initdb.sql not running in Windows Server 2016 or 2019 in Docker

I installed Docker EE on Windows Server 2016 and 2019. I am spinning up a PostgreSQL container and have an initdb.sql script to initialize the database.

I am using Windows containers, and have tested the script both in docker and docker-compose on Windows 10 in Windows Containers mode. The moment I move it to Windows Server 2016/2019, the database spins up but it does not run the initdb.sql script.

Here is my docker-compose

version: "3"

networks:
  localnetwork:

services:

  postgres_db:
    image: stellirin/postgres-windows:12-1809
    restart: unless-stopped
    environment:
      - POSTGRES_USER=${DB_USER}
      - POSTGRES_PASSWORD=${DB_PASSWORD}
    volumes:
      - .\admin\${ENV:-dev}\dbms\init:C:\docker-entrypoint-initdb.d
    ports:
      - "5432:5432"
    networks:
      - localnetwork

How do I get Windows Server 2016/2019 to run the initdb.sql? I cannot docker exec into the container either because it returns Access is denied.

Note, Access is denied is also the case in Windows 10. But I can use Docker Desktop's interface to somehow get into the container to check. Docker EE has no Docker Desktop so this cannot be done.

docker-compose docker init postgresql windows

this happens when the 1a) data directory for the postgres windows user account does not have access or 1b) you are mounting a docker volume for a directory which is shared between Windows and the docker host from user thomas here

1a. To check permissions on PG_DATA directory run this

// check your dir access
cacls "c:\YourPath\pgdata\dir"

1b) issue if the directory is shared between windows and docker host

docker run -p 54332:5432 -v /tmp/volumes/postgres/log:/var/log/postgresql -v /tmp/volumes/postgres/lib:/var/lib/postgresql mypostgres

2. Also please check, if you have a previous crashed file

Manually remove the postmaster.pid file at \postgres\directory\postmaster.pid and start it again, then it should be fine.

3. From your container you have to export/publish ports to your host with the publish command -p option :

docker run -it -v D:/postgres:/home/dump --name some_postgres -p 5432:5432 -e POSTGRES_PASSWORD=root -d postgres

4. check your fire wall rules

The easiest way to fire up docker with postgres & a nice ref to help you

docker run --name postgres-db -e POSTGRES_PASSWORD=docker -p 5432:5432 -d postgres

Maybe easier to pull a fresh image

Pull down the latest [Postgres image from the Docker Hub][4]
