Updating the Toil Gitlab Runner

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”.

Remove the old runner:

helm uninstall --namespace toil gitlab-toil-kubernetes-runner

Install the new runner with the old config:

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

That's it.
