# Enable Hyper-V & Containers and Install Docker on Window Servers

Steps for enabling necessary features and installing necessary packages for deploying docker and containers on Windows Server 2016

### Step 1: Install and Import  Docker Package Provider 

```bash
Install-PackageProvider -Name NuGet -MinimumVersion 2.8.5.201 -Force
Install-Module DockerMSFTProvider
Import-Module -Name DockerMSFTProvider -Force
Import-Packageprovider -Name DockerMSFTProvider -Force
```

Use `Find-Package` to verify the new docker package is available:

```

PS C:\> Find-Package docker

```

### Step 2 (VM Only) : Enable Nested Virtualization

Make sure the virtual machine is down.

#### For Windows-VM:

```
# Enable Nested Virtualization
Set-VMProcessor -VMName <VMName> -ExposeVirtualizationExtensions $true
# In order for network packets to be routed through two virtual switches
Get-VMNetworkAdapter -VMName <VMName> | Set-VMNetworkAdapter -MacAddressSpoofing On
```

#### For Xen-Server

Check if physical cpu has the flag *vmx* which stands for virtualization support enabled in BIOS for intel VT-x.

In the cfg file, add the following parameters:

```
nestedhvm=1 
hap=1
```

Restart the virtual machine.

### Step 3: Enable Hyper-V and Container Windows Features

In PowerShell, run the following commands:

```
Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V -All
Enable-WindowsOptionalFeature -Online -FeatureName containers -All
```

Restart the virtual machine.

### Step 4: Install Docker

`Install-Package -Name Docker -Source DockerDefault`

{% hint style="danger" %}
`If you have not done the system update on the vm, you will get the following error:` WARNING: Cannot verify the file SHA256. Deleting the file.

make sure you have the latest update patch on the machine.
{% endhint %}

```
