Wirtual Machine with Windows Server from Azure doesnt run Linux based Docker Container

Question

I try to run a Docker container based on Linux on Virtual Machine from Azure with Windows Server 2019.

I work with a lot of tutorials for that, I enabled experimental flags, so docker version show:

 PS C:\Users\azure> docker version
Client: Docker Engine - Enterprise
 Version:           19.03.5
 API version:       1.40

 OS/Arch:           windows/amd64
 Experimental:      false

Server: Docker Engine - Enterprise
 Engine:
  Version:          19.03.5
  API version:      1.40 (minimum version 1.24)
  Go version:       go1.12.12
  Git commit:       2ee0c57608
  Built:            11/13/2019 07:58:51
  OS/Arch:          windows/amd64
  Experimental:     true

And docker info:

But finally, when I run any Linux container I got this error:

PS C:\Users\azure> docker run --platform=linux hello-world:linux
docker : C:\Program Files\Docker\docker.exe: Error response from daemon: failed to start

I miss something in Azure? In VM config?

Answer 1

This is how I got Docker to install Properly in an Azure Virtual Machine:

1. Ensure that the VM SKU size supports virtualization, and I usually use Standard_D2s_v3 or Standard_D2s_v4.

2. Ensure you do not enable Trusted Launch Virtual Machines because this feature disables virtualization inside the VM.

I blogged about the details about how to get Docker to run in Azure here: Running Docker in an Azure Windows Virtual Machine – Not so fast!

Answer 2

I solve my problem and it wasn't a problem with config, docker, or with Windows Server.

The problem was hardware - when you select Azure processor you should use a processor with nested virtualization. The solution is described here: https://blog.darrenjrobinson.com/azure-vm-docker-createcontainer-error-0xc0370102/
