• Fastest
• Higher Density
• Host OS = Container OS (maj.min.rev)
• Faster than VM
• Isolation
• Host OS ≠ Container OS

5. Install Docker on Windows 10
Enable ‘Container’ and ‘Hyper-V’ features
Download and Install, Docker for Windows CE (edge channel)

6. Install Docker on Windows Server 2016
Enable ‘Container’ features
Install-Module -Name DockerMsftProvider -Repository PSGallery –Force
Install-Package -Name docker -ProviderName DockerMsftProvider
Restart-Computer -Force
Enable ‘hyper-v’ server role – only for Hyper-V Isolation

7. Install Docker on a VM
Enable nested virtualisation on the VM
Set-VMProcessor -VMName <VMName> -ExposeVirtualizationExtensions $true
