Windows w/ Linux Container - "The request is not supported"


#1

I have two Windows 2019 servers, one that is able to run Linux containers without any issues, and the other that can’t. They are running identical versions of docker (18.09). I have tried rebuilding the server that can’t run the Linux containers from scratch numerous times. CreateComputeSystem — The request is not supported. Why is this happening!!!

Both servers have the exact same Linuxkit LCOW kernel and initrd.img files (https://github.com/linuxkit/lcow/releases/tag/v4.14.35-v0.3.9) in C:\Program Files\Linux Containers.

Here is the docker info, version, and what happens when I try to run an Ubuntu image on each of them:

#2

I currently have the same issue as you but on a custom made “docker” system (compiled my own dockerd and docker client).

I am starting to wonder whether I pulled some new code related to HCS which is not supported yet in my Windows build (Windows Pro version 1809)…


#3

My problem turned out to be that I needed to do Install-WindowsFeature Containers,Hyper-V before docker.


#4

Thanks a lot, had the same issue.
I activated Hyper-V feature but not the Containers one!
