Google Cloud: AutoScale Windows runner with GitLab

GitLab CI/CD
1

Hi!

We are running GitLabCI autoscale on GCP. It works with Debian runners. Now I’d like to add windows runner too. Created windows image with openssh and modified GitLabCI runner manager config.toml to include windows.

[[runners]]
  name = "GCP Autoscale GitLab-Runner Windows"
  url = "https://gitlab.abcd.com/"
  token = "token1"
  executor = "docker+machine"
  [runners.custom_build_dir]
  [runners.docker]
    tls_verify = false
    image = "debian:buster-slim"
    privileged = false
    disable_entrypoint_overwrite = false
    oom_kill_disable = false
    disable_cache = false
    volumes = ["/cache", "/etc/docker/certs.d:/etc/docker/certs.d:ro"]
    network_mode = "host"
    shm_size = 0
  [runners.machine]
    IdleCount = 0
    IdleTime = 600
    MachineDriver = "google"
    MachineName = "autoscale-windows-%s"
    MachineOptions = ["google-project=abcd", "google-zone=us-west1-c", "google-machine-type=n1-standard-1", "google-use-internal-ip=true",  "google-machine-image=abcd/global/images/autoscale-gitlab-runner-windows-agent" ]
    OffPeakTimezone = ""
    OffPeakIdleCount = 0
    OffPeakIdleTime = 600

Then create simple gitlabci.yml job like

test1:
  stage: test
  script:
    - echo "Hello from Windows"

When running the pipeline, it successfully launches Windows runner on GCP but it fails to ssh into runner. Log shows something like this

 Error creating machine: Error detecting OS: Too many retries waiting for SSH to be available.  Last error: Maximum number of retries (60) exceeded  driver=google

Does GitLabCI Autoscale support Windows-runners? thanks for any pointers
