Passthrough USB HDD

[Antroxin]

Hi, I would like to know if it is possible to passthrough a physical USB external HDD connected to the Host to the docker via volumes

• /dev/sdb:/xxx

You can add this to your compose file:

environment:
  DEVICE2: "/dev/sdb"
devices:
  - /dev/sdb

and it should work. But only do it when you have a backup of your USB drive. Because if something goes wrong and Windows format the device for example, its better to be safe.

Thanks Kroese for your help.

Whenever I add the device to the docker-compose config file, docker does not work. The log says: ❯ Starting Windows for Docker v1.03... ❯ For support visit https://github.com/dockur/windows ❯ ERROR: KVM acceleration not detected (device file missing), this will cause a major loss of performance. ❯ ERROR: See the FAQ on how to enable it, or continue without KVM by setting KVM=N (not recommended).

This is my configuration: ` windows: image: dockurr/windows container_name: windows devices:

• /dev/kvm cap_add:
• NET_ADMIN networks:
• proxy ports:
• 8006:8006 stop_grace_period: 2m restart: unless-stopped volumes:
• /opt/containers/windows:/storage devices:
• /dev/sdb environment: RAM_SIZE: "8G" DEVICE2: "/dev/sdb"`

Looks like you removed

    devices:
      - /dev/kvm

That should be there as well.

Yes, it was devined devices twice, grouping then in only one, now it is working and HDD is detected and accessed in Windows. Thanks!
