Installing docker on azure virtual machine windows 10

Question

I am getting an error upon installing docker on azure virtual machine.

m/c configuration: azure vm, windows 10 enterprise, Intel 2.4 GHz, 7 GB RAM, 64-bit operating system, x64-based processor. I went through a few blogs and they asked me to enable nested virtualization on azure vm as follows.

Set-VMProcessor -VMName MobyLinuxVM -ExposeVirtualizationExtensions $true

But this also didn't help and the virtual m/c MobyLinuxVM failed to start. I have installed Hyper-V and Container components from windows features. But the error shows "because one of the Hyper-V components is not running" whereas all the components of Hyper-V are running. I checked the task manager performance tab and I don't see the virtualization option there. I can't modify the virtualization settings in the BIOS as I am installing docker on an Azure VM. Also I tried disabling the windows firewall but that didn't help. So how to run docker on azure virtual m/c windows 10 enterprise.

Answer 1

Here is a solution if you are getting this error on Azure Windows 10 VM where you have installed Docker:

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

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

2. Ensure Windows Containers feature is enabled by running PowerShell cmdlet:

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

3. 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

After running all of the above and you restart the Azure VM, Docker should be starting normally.

Answer 2

Azure doesnt yet allow for nested virtualization.
You need to use DSv3 or E3 instances for that. Just use docker like you normally would
