Unable to run build for gitlab-ci using docker on windows server

Question

I'm trying to setup CI for dotnet 4.6 project. I'm using GitLab v8.5.1 with shared runner v1.0.4.

I have installed a Windows Server 2016 CTP 4 that supports docker and have created an image for gitlab ci runner based on the microsoft windowsservercore image.

There is my .toml

concurrent = 1

[[runners]]
  name = "docker runner 1"
  url = "http://my_server/ci"
  token = "my_token"
  tls-ca-file = ""
  executor = "docker"
  builds_dir="c:\builds"
  [runners.docker]
    image = "windowsservercoregitlab:latest"
    host = "tcp://127.0.0.1:2375"
    privileged = false

and .yaml files

stages: - build

job:
  stage: build
  script:
  - echo "Test run my build..."

When i run a build it fails with log:

gitlab-ci-multi-runner 1.0.4 (014aa8c)
Using Docker executor with image windowsservercoregitlab:latest ...

ERROR: Build failed with: API error (500): hcsshim::ImportLayer - Win32 API call returned error r1=2147942402 err=The system cannot find the file specified. layerId=c1ef764e74b9a93262141455f30229877e80ed9c04b93af6bc73e03568c33790 flavour=1 folder=C:\ProgramData\docker\windowsfilter\c1ef764e74b9a93262141455f30229877e80ed9c04b93af6bc73e03568c33790-1950806090

Obviously, it trying to create some volume and fails, but i can't understand which volume or how to setup it properly.

How could i solve this problem?

Answer 1

As I recalled from their most recent Webcast . Currently Windows runners only support 'Shell' and dockers are for Linux/Unix systems (Not sure about Mac). With that said, I have no issue using shell executor.
