gitlab runner - network_mode = "host" - docker

Question

I want to setup CI/CD in GitLab.
So i installed docker and the gitlab-runner on linux, created a config for a runner and started everything. So far so good.
The runner works, and docker works.
But i am using the linux subsystem from windows, so i need to run the docker container with parameter "--network host" otherwise they not gonna work.
So right now i try to configure the gitlab-runner to use the host network via the "network_mode" parameter. But it does not work. I get the same error as if i would run a docker container directly and without the "--network host".
The error:
WARNING: Preparation failed: Error response from daemon: oci runtime error: container_linux.go:265: starting container process caused "process_linux.go:368: container init caused \"process_linux.go:351: running prestart hook 0 caused \\"error running hook: exit status 1, stdout: , stderr: time=\\\\"2019-04-12T18:42:33+02:00\\\\" level=fatal msg=\\\\"failed to add interface vethfc7c8d1 to sandbox: failed to get link by name \\\\\\\\"vethfc7c8d1\\\\\\\\": Link not found\\\\" \\n\\"\"" (executor_docker.go:423:16s) job=123project=123 runner=123
This is my config:
concurrent = 1
check_interval = 0
[session_server]
session_timeout = 1800
[[runners]]
name = "MyHostName"
url = "https://my.gitlab.url/"
token = "SoMeFaNcYcOdE-e"
executor = "docker"
[runners.docker]
tls_verify = false
image = "beevelop/ionic:latest"
privileged = true
disable_entrypoint_overwrite = false
oom_kill_disable = false
disable_cache = false
volumes = ["/cache"]
shm_size = 0
network_mode = "host"
[runners.cache]
[runners.cache.s3]
[runners.cache.gcs]
My question is how do i force the gitlab runner to create the containers to use the host network like with the docker parameter: "--network host"

Answer 1

I was unable to solve the problem directly, but i found an alternative way which is a lot better.
I configured the GitLab Container Registry
of the repository to upload and white list a custom docker image and then enabled the Shared Runners of my company. The custom image i uploaded was created via a Dockerfile using docker for windows, avoiding the struggle of the buggy docker in the linux subsystem of windows. Now i can execute my CI pipeline flawlessly and have full control over the used image and do not have to keep my local machine running.
