There's a Helm chart included in the repo. To use it, you'll need to create a service account on GCE with the following permissions:
compute.instanceGroupManagers.getcompute.instanceGroupManagers.update
Then, create a secret with the service account credentials:
$ kubectl create secret generic gitlab-gce-autoscaler --from-file=service-account-creds.json=service-account.json
secret/gitlab-gce-autoscaler createdNow install the chart:
$ helm upgrade --install gitlab-gce-autoscaler helm/gitlab-gce-autoscaler -f myvalues.yaml
