Hi,

  • Windows 10 Pro 21H1
  • Docker Desktop 4.0.1
  • WSL2
  • Are you running inside a virtualized Windows e.g. on a cloud server or a VM: No.

I’m docker n00b , newly started to using docker desktop for windows and getting these warnings with “docker info”:

I would like to solving the problem.

…

WARNING: No blkio throttle.read_bps_device support
WARNING: No blkio throttle.write_bps_device support
WARNING: No blkio throttle.read_iops_device support
WARNING: No blkio throttle.write_iops_device support

  • Windows 11 Pro 22H2
  • Docker Desktop 4.12.0
  • Ubuntu 22.04.1 LTS running native on WSL2

WARNING: No blkio throttle.read_bps_device support
WARNING: No blkio throttle.write_bps_device support
WARNING: No blkio throttle.read_iops_device support
WARNING: No blkio throttle.write_iops_device support

It’s a warning that indicates that the kernel does not support blkio throttle settings for the containers.

If you really need that feature, you will have to compile your own WSL2 kernel and configure WSL2 to use it. The origin and fix are outside of docker’s reach.
