How to send logs from Gitlab Pipeline jobs to Graylog?

Question

I need to send logs like those from jobs executed in Gitlab pipeline to Graylog. Is it possible to do it straight from Gitlab runner containers?

I have a docker installed on my Virtual Machine with one Gitlab runner container and I would like to send job logs from Docker to Graylog server. I checked docker documentation and set logging driver to gelf in /etc/docker/daemon.json like this.

{
  "log-driver": "gelf",
  "log-opts": {
    "gelf-address": "udp://10.10.10.4:12201"
  }
}

I receive some logs from this runner container but there are no any logs from Gitlab Pipeline's jobs execution. It seems like runner containers doesn't store those logs? I tried docker logs gitlab-runner command on another machine without gelf driver and it doesn't show logs from jobs either. Is there some way to solve it?

Job traces are sent to GitLab and stored as artifacts. If you self-host gitlab, you can forward the logs from your GitLab server using the log forwarder. By default, the logs will be with other artifacts under var/opt/gitlab/gitlab-rails/shared/artifacts

Job logs are otherwise not present in the runner.
