Build Docker Engine for Windows in Docker

To build the Docker Engine for Windows Server 2016 from source with only with Docker and Git on the host use this setup.

This Dockerfile.windows made it into the docker/docker repo with PR #18348 but is now updated to fit into the Windows CI.

But the basic idea was to just use Windows Server 2016 and Docker and nothing else on the host machine (ok, Git would be nice to clone this dockerfiles-windows repo) to build the Docker Engine for Windows.

If you want to build Docker Engine on your own then just run build.bat.

Build a pull request

If you are interested in a pull request and want to try it out before it gets merged, you can run build.bat with the pull request number.

To build eg. this PR moby/moby#28964 which switches to make.ps1, run

.\build.bat 28964

The binaries for Docker Client and Docker Daemon are copied into the binary sub directory.

Test the binaries

Open an administrator PowerShell and run these commands to replace the Docker Client and Daemon. You may make a backup of your current binaries.

Stop-Service docker
copy binary\docker.exe "C:\Program Files\docker\docker.exe"
copy binary\dockerd.exe "C:\Program Files\docker\dockerd.exe"
Start-Service docker
