Hello im using docker for VM

and when want to deploy getting this error

Failed to deploy a stack: failed to create compose project: failed to load the compose file : validating /data/compose/41/docker-compose.yml: volumes must be a mapping

This is my code :

services:
  windows:
    image: dockurr/windows:latest
    container_name: windows
    environment:
      VERSION: "10"
      CPU_CORES: "8"
      RAM_SIZE: "8G"
    devices:
      - /dev/kvm
      - /dev/net/tun
    cap_add:
      - NET_ADMIN
    ports:
      - 8006:8006
      - 3389:3389/tcp
      - 3389:3389/udp
    volumes:
      - data:/storage:rw

    stop_grace_period: 10m

volumes:
  data:

Any idea to why this is happening?

Please format it as code block, like you did with the compose file.

done please check again

Your compose file looks correct. Nothing in the docs indicate that the volume short syntax suddenly changed from a list to a map.

You are on a release candidate of Docker 29, so errors can be expected.

Can you try docker compose config to determine whether the problem is in the compose cli plugin?

this is what i get

no configuration file provided: not found

8

Of course, you need to be in the folder where the compose file is located, or specify the compose file with -f <path to compose file>

sorry im kinda dumb this is what i get T_T

root@DESKTOP-C6EBBCB:/home/inuko# docker compose config -f /usr/libexec/docker/cli-plugins/docker-compose
unknown shorthand flag: ‘f’ in -f

I should have been more precise.

Please execute:

docker compose -f <path to the compose file> config

Where <path to the compose file> is the compose file that contains the content you shared in your first post.
