Building on Windows

This part of the repo contains the Dockerfile of the image used to build Windows container which will be used to build Datadog Agent for Windows.

[Experimental] Converting Dockerfile to Powershell script

Run dockerfile-to-powershell.py script to convert Windows Dockerfile instructions to the logically equivalent Powershell script which will make clean Windows machine ready for building Agent for Windows platform (without Docker involvement).

Example of the generated Powershell file is added to the repo as dockerfile-to-powershell-generated-sample.ps1 but it will be outdated next time the Dockerfile is changed (in the future we may automatically regenerate it).

Phase 1: Generate Powershell script

You need only the script itself and the Dockerfile (and requirements.txt - to run pip install -r requirements.txt).

Example

  .\dockerfile-to-powershell.py 
       -d .\Dockerfile 
       -p .\dockerfile-to-powershell-generated-sample.ps1
       -a WINDOWS_VERSION=1809
       -a DD_TARGET_ARCH=x64

Phase 2: Create Windows Build Machine

Prerequisites

Example

cd C:\
Powershell
.\dockerfile-to-powershell-generated-sample.ps1 -DockerRepoPath C:\datadog-agent-buildimages

Note: On the moderately beefy VM this Powershell script may take 30-40 minutes to complete.

Phase 3 (Optional): Build Agent

Now we are ready to build Agent. We can run exactly the same commands as with the Docker-based Windows build

Example

git clone https://github.com/DataDog/datadog-agent.git C:\mnt
set OMNIBUS_TARGET=main&set RELEASE_VERSION=nightly&set MAJOR_VERSION=7&set PY_RUNTIMES=3&set TARGET_ARCH=x64&c:\mnt\tasks\winbuildscripts\buildwin.bat

Caveats:

  • C:\mnt will be checked by the script and is required directory containing Agent sources
  • Environment variables command line should not have spaces around "&"
  • We have seen cases when "ridk enable" commands had to run
