Getting "The request is not supported" while trying to execute docker run about lcow

[alatas]

I had the same issue on a clean win2019(1809) + docker(v19.03.2) + lcow (v4.14.34)
I enabled the hyper-v feature from server configuration manager, and restarted the server. the issue was solved.

This error comes from the image you're referencing not being compatible with the current OS you're running.

Since busybox is a linux image, you'll have to specify --isolation=hyperv in your run command. But I'm not sure this is fully supported yet.

I'm also fairly certain that Server 2019 is not officially supported with Docker EE engine, but you might try updating to 18.09.7 just to see, or try version 19.03.0-rc2 if you're feeling brave (but they're having some issues with the hash on the package file last I checked.)

Correction:

It may be related to the way that you're phrasing your run command. I discovered this the hard way.

For example:

docker run -d -p 9000:9000 --name portainer --restart always -v \\.\pipe\docker_engine:\\.\pipe\docker_engine -v E:\Portainer:C:\data portainer/portainer:windows1809-amd64

works. ... But

docker run -d --restart=always --mount type=npipe,source=\\.\pipe\docker_engine,destination=\\.\pipe\docker_engine --mount type=bind,source=E:\Portainer,destination=C:\data -p 9000:9000 --name portainer portainer/portainer:windows1809-amd64

throws the The request is not supported error.

I would try using different parameters or alternative parameters to what you have and see if changing something gives you the same errors.
