title: How to increase gitlab job concurrency on gke kubernetes runner?
body: <p>I created two gitlab runners through <a href="https://about.gitlab.com/blog/2020/03/27/gitlab-ci-on-google-kubernetes-engine/" rel="nofollow noreferrer">the standard default runner creation UI in gitlab</a> (3 node n1-standard-4 gke cluster). <a href="https://gitlab.com/gitlab-org/gitlab-runner/-/blob/master/docs/configuration/autoscale.md#runner-global-options" rel="nofollow noreferrer">I've been trying to increase my gitlab runner to handle more than the default 4 concurrent jobs, but for some reason the limit is still capped at running only 4 jobs at once.</a></p>
  <p>In GCP I changed the <code>concurrent</code> value in the <code>config.toml</code> from 4 to 20 under the config maps <code>runner-gitlab-runner</code> and <code>values-content-configuration-runner</code> that were generated in my cluster found under the <a href="https://console.cloud.google.com/kubernetes/config" rel="nofollow noreferrer">https://console.cloud.google.com/kubernetes/config</a> menu.</p>
  <p>What else do I need to change to allow my gitlab runners to run more than 4 jobs at once?</p>
  <p><a href="https://gitlab.com/gitlab-org/gitlab-runner/-/blob/master/docs/configuration/autoscale.md#runners-options" rel="nofollow noreferrer">Do I need to change the <code>limit</code> in the runner options?</a> If so, where would I find that config in GCP?</p>
