gitlab ci cannot build windows container

I am trying to build windows container using https://gitlab.com, but I didnot find if this is supported or not.

I made a test with a really simple Dockerfile:

FROM mcr.microsoft.com/windows/servercore:ltsc2019
CMD echo "Hello World from Windows"

Using .gitlab-ci.yml

image: docker
services:
- docker:dind

variables:
  DOCKER_HOST: tcp://docker:2375
  DOCKER_DRIVER: overlay2

before_script:
  - docker login -u gitlab-ci-token -p $CI_JOB_TOKEN $CI_REGISTRY

windows:
  stage: build
  script:
  - docker build -t ${CI_REGISTRY}/${CI_PROJECT_PATH}:${CI_COMMIT_REF_SLUG} . 
  - docker push ${CI_REGISTRY}/${CI_PROJECT_PATH}:${CI_COMMIT_REF_SLUG}

It fails with :

image operating system "windows" cannot be used on this platform
ERROR: Job failed: exit code 1

Looking for the documentation of gitlab-runner, it seems supported https://docs.gitlab.com/runner/executors/#selecting-the-executor.

Is there a way to build a windows container from the online service ?

@mpromonet solution no longer works without adding an extra line to start the docker service because now is not starting by default like before.

Add a before_script section with - Start-Service -Name "docker"

Updated example:

windows:
  stage: build
  tags:
    - shared-windows
    - windows
    - windows-1809
  before_script:
    - Start-Service -Name "docker"
  script:
    - docker login -u $CI_REGISTRY_USER -p $CI_REGISTRY_PASSWORD $CI_REGISTRY
    - docker build -t ${CI_REGISTRY}/${CI_PROJECT_PATH}:${CI_COMMIT_REF_SLUG} . 
    - docker push ${CI_REGISTRY}/${CI_PROJECT_PATH}:${CI_COMMIT_REF_SLUG}

Since January 2020 it is possible to build a windows container using online service using the Windows Shared Runners (beta).

Today, we are happy to announce that Windows Shared Runners hosted by GitLab is available in beta. As we are starting to roll out this important service to our community, we invite you to help shape the direction of CI/CD tooling for the Windows ecosystem on GitLab.com

For instance, using the following .gitlab-ci.yml

windows:
  stage: build
  tags:
  - shared-windows
  - windows
  - windows-1809
  script:
  - docker login -u $CI_REGISTRY_USER -p $CI_REGISTRY_PASSWORD $CI_REGISTRY
  - docker build -t ${CI_REGISTRY}/${CI_PROJECT_PATH}:${CI_COMMIT_REF_SLUG} . 
  - docker push ${CI_REGISTRY}/${CI_PROJECT_PATH}:${CI_COMMIT_REF_SLUG}

With a simple Dockerfile

FROM mcr.microsoft.com/windows/servercore:ltsc2019
CMD echo "Hello World from Windows"

The pipeline execution result enter image description here

This should be supported with GitLab 1.11 (May 2019)

Windows Container Executor for GitLab Runner

In GitLab 11.11 we are pleased to add a new executor to the GitLab Runner for using Docker containers on Windows.

https://about.gitlab.com/images/11_11/windows-container.png

Previously, using the shell executor to orchestrate Docker commands was the primary approach for Windows, but with this update you are now able to use Docker containers on Windows directly, in much the same way as if they were on Linux hosts.
This opens up the door for more advanced kinds of pipeline orchestration and management for our users of Microsoft platforms.

Included with this update is improved support for PowerShell throughout GitLab CI/CD, as well as new helper images for various versions of Windows containers.
Please note that your own Windows runners can be used with GitLab.com, but are not currently available as part of the shared public fleet.

This is from issue 535: see the documentation "Using Windows containers".

It has limitations, but it is a good first step.

As far as I know, the runners provided by GitLab.com are all Linux based. You'll need to provide your own runner with a Windows-based Docker engine to build a Windows Docker image.
