'unknown mount option' when podman-compose

Question

I am using podman-compose instead of docker-compose.

My docker-compose.yml had no problems when using docker-compose, but it makes an error with podman-compose.

docker-compose.yml:

version: "3.9"
services:
  mysql:
    image: docker.io/mysql
    container_name: mysql
    hostname: mysql
    volumes:
      - D:\mysql\test\data:/var/lib/mysql
    environment:
      MYSQL_ROOT_PASSWORD: "password"
      MYSQL_TCP_PORT: 8026
    ports:
      - "8026:8026"

When podman-compose up:

['podman', '--version', '']
using podman version: 4.3.1
** excluding:  set()

ValueError: unknown mount option /var/lib/mysql

I think that it read colon(:) at Windows drive(D:) as delimeter so the last field /var/lib/mysql is read as options like ro, rw. But I don't know how I can solve this.

This page (https://github.com/containers/podman/blob/main/docs/tutorials/podman-for-windows.md) gives a definition for 'Unixy' Windows paths. my references then went from: d:/path to /d/path Have a look and let us know how you get on
