devenv

Windows Dev Env

This folder contains a few scripts to help get setup with a Windows Development Environment. There is a Powershell script that uses Chocolatey to install the recommended dependencies to build the agent and some Packer files to build ready-to-use Vagrant boxes.

If you already have a Windows machine and just want to install the required dependencies to build the agent, see Using the Powershell script. If you need to setup a new environment, including building your own Windows development image for various virtual machine providers, see Using Packer to generate the base boxes.

Using the Powershell script

Copy the script devenv\scripts\Install-DevEnv.ps1 on the target machine and then in an Administrator Powershell prompt:

Set-ExecutionPolicy Bypass -Scope Process -Force; <path_to_ps1>\Install-DevEnv.ps1

Using Packer to generate the base boxes

There is a Ruby template file to generate the various Packer combinations. To generate the Packer file and then invoke Packer the Invoke! library is used.

To generate the packer.json file (here for Windows 10): inv packer.build --os=windows-10 --provider=virtualbox-iso

Where the valid os values are:

• windows-10
• windows-server

And the valid provider values are:

• virtualbox-iso
• vmware-iso
• parallels-iso

The default values are windows-10 and virtualbox-iso.

Then, it's just a matter of building the images: packer build packer.json

Note: For Parallels, you'll also need to install the Virtualization SDK: brew cask install parallels-virtualization-sdk

Note: By default this will launch the VM for the selected provider (Virtualbox, VMWare, Parallels) and the VM will consume 2GB of RAM. The provider must be installed on the machine. Parallel building is not supported because it is a massive strain on the building machine and frequently resulted in crashes.

Note: The base boxes are based on Windows 10 Enterprise Evaluation (1903) and Windows Server 2019 Evaluation ISOs. They are good for 90 days, after that a valid license must be provided.

Using Vagrant to start a dev VM

The provided Vagrantfile expects the box to exist in the same directory.

To start a VM: vagrant up win-10-prl --provider=parallels

Then, to run commands inside the VM: vagrant winrm -c "ipconfig" win-10-prl

The VMs are customized to:

• Allocate 4GB of RAM instead of 2GB default.
• Enable linked clones so that multiple versions of the same VMs can share much of the storage.
• Enable nested virtualization to allow running docker containers in the VM. This does not work for Virtualbox.

Note: By default the Vagrantfile will attempt to mount your "$GOPATH/src/github.com/DataDog" folder in the VM in "/Users/dogdev/go/src/github.com/DataDog"

VMWare Vagrant Issue

The Vagrant VMWare integration is a paid module (separate from the VMWare license).

There are a few alternatives to this:

• Use the FOSS equivalent
• Use mech, which replaces Vagrant
• Use tar to extract the VMWare files and use them directly:

mkdir vm
cd vm
tar zxvf ../windows_10_ent_vmware.box

Third party notice

Two third party files are used and adapted:

• devenv\scripts\Enable-WinRM.ps1 from https://github.com/StefanScherer/packer-windows/blob/my/scripts/enable-winrm.ps1
