Setting amount of Unicorn workers for Gitlab Runner running in Docker

GitLab CI/CD
1

How do I set the amount of unicorn workers for Gitlab Runner, when using the official Docker image?

Is it possible to do it while starting Gitlab-Runner?
Below is the command I am using to start the runner:

docker run -d --name gitlab-runner --restart always \
  -v /srv/gitlab-runner/config:/etc/gitlab-runner \
  -v /var/run/docker.sock:/var/run/docker.sock \
  gitlab/gitlab-runner:latest

I added gitlab.rb with

 unicorn['worker_processes'] = 3
 unicorn['worker_timeout'] = 60

to /srv/gitlab-runner/config, stopped and destroyed it with

docker stop gitlab-runner && docker rm gitlab-runner

And restarted it with the command above, but it still refuses to run jobs concurrently

@MKTronics The gitlab.rb file is for GitLab’s configuration, not the runner. Please see the advice for configuring the runner via the config.toml file here:

@markglenfletcher Yeah, I just realized it.
It would have been easier for me if I didn’t use unicorn workers in the earlier setup of my server.
