如何在 Windows 10 上运行 docker？

Question

I just installed Docker on Windows 10. When I run Docker as an administrator I get the following error:

Unable to create: The running command stopped because the preference 
variable "ErrorActionPreference" or common parameter is set to Stop: Hyper-V 
encountered an error trying to access an object on computer 'WP2975' because 
the object was not found. The object might have been deleted. Verify that 
the Virtual Machine Management service on the computer is running.

I checked if Hyper-V is running on the computer.

I also did the following in powershell:

Ensure Windows Hyper-V featutes are enabled by running PowerShell cmdlet:

 Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V -All -Verbose

Ensure Windows Containers feature is enabled by running PowerShell cmdlet:

 Enable-WindowsOptionalFeature -Online -FeatureName Containers -All -Verbose

Ensure Hypervisor is set to auto start in the Boot Configuration Database (BCD) by running in elevated command prompt the command:

 bcdedit /set hypervisorlaunchtype Auto

( Found it on: Failed to start the virtual machine 'MobyLinuxVM' because one of the Hyper-V components is not running )

But nothing helps.

I also reinstalled docker two times.

Please do make sure that the following three windows services are in running state

HV Host Service
Hyper-V Host Compute Service
Hyper-V Virtual Machine Management

Answer 2

If Windows 10 you're referring to has an ancient edition (lower then anniversary, ie 1607) there is no chance in hell you can get it working. To check version of your OS run 'winver'. The problem with these editions is that they don't support nested virtualization Docker require.

Now, it's not clear WHERE are you running your VM. If it's VMWare on your PC it should be relatively easy to fix, but if it's Cloud, can be a different story. The thing is that in Azure, for instance, not all VMs support nested virtualization, so if you hastened to provision a VM, it might be a problem. If you want to get it right, use v3 VM types and up ( refer this article for more info ).

In my case 'HV Host Service' didn't work as well, but fortunately I was able to resize a VM to a proper tier (v3) and voila! Docker started right away.
