The script works great (mostly) :-)

After lots of messing about yesterday trying to manually install and set up Windows containers on Azure, I was pleased to find the script at https://github.com/Azure/azure-quickstart-templates/tree/master/windows-server-containers-preview . The first part of the install went without a hitch. Towards the end it failed though with :-

C:\Windows\system32\update-containerhost.ps1 : Could not find a part of the path 'C:\ProgramData\docker\config\daemon.json'.
At C:\windos-containers.ps1:11 char:5
- .\update-containerhost.ps1
- ~~~~~~~~~~~~~~~~~~~~~~~~~~
- CategoryInfo : NotSpecified: (:) [Write-Error], WriteErrorException
- FullyQualifiedErrorId : Microsoft.PowerShell.Commands.WriteErrorException,update-containerhost.ps1

Fortunately yesterday I'd come across (https://msdn.microsoft.com/en-us/virtualization/windowscontainers/quick_start/quick_start_windows_server).

I ran steps 2 and 4 and before the note about creating a rule in a Network Security Group I thought I'd cross my fingers and http to whatever.northeurope.cloudapp.azure.com.

SUCCESS!

Start with windows-containers.ps1 and update-containerhost.ps1, then inspect the reported failure involving C:\ProgramData\docker\config\daemon.json. Reproduce the Windows containers setup and compare the script flow with the documented manual steps. Done means the script completes without this missing-path error and the resulting container host is usable.
