Updating the Toil Gitlab Runner

New Openstack Instructions

To update the runner, you probably should now just destroy the old instance and make a new instance, following the instructions at Gitlab CI Autoscaling Setup.

Old Kubernetes Instructions

To update Toil's Gitlab runner, you'll first need a kube config to access the cluster (email Erich Weiler).

Next, run this to get the current runner config:

helm -n toil get values gitlab-toil-kubernetes-runner

This will print something like the following (relevant part shown):

checkInterval: 30
concurrent: 20
gitlabUrl: https://ucsc-ci.com/
imagePullPolicy: Always
rbac:
  create: false
  serviceAccountName: toil-svc
runnerRegistrationToken: averyverysecrettoken
runners:
  config: |
    [[runners]]
      name = "Kubernetes Runner"
      output_limit = 40960
      [runners.kubernetes]
        namespace = "toil"
        image = " "
        poll_timeout = 86400
        privileged = true
        service_account = "toil-svc"
        cpu_limit = "4000m"
        cpu_request = "4000m"
        memory_limit = "15Gi"
        memory_request = "15Gi"
        ephemeral_storage_limit = "20Gi"
        ephemeral_storage_request = "20Gi"
        service_cpu_limit = "4000m"
        service_cpu_request = "4000m"
        service_memory_limit = "8Gi"
        service_memory_request = "8Gi"
        service_ephemeral_storage_limit = "20Gi"
        service_ephemeral_storage_request = "20Gi"
        helper_cpu_limit = "500m"
        helper_cpu_request = "500m"
        helper_memory_limit = "256M"
        helper_memory_request = "256M"
        helper_ephemeral_storage_limit = "20Gi"
        helper_ephemeral_storage_request = "20Gi"

Write this into a file called “values.yml”.

Update so that helm knows what the latest version is:

helm repo update

Finally, update the runner:

helm upgrade --namespace toil gitlab-toil-kubernetes-runner -f values.yml gitlab/gitlab-runner

That's it, though you can sanity check here to see the new runner (and what should be the updated version):
