This is when the tekton-pipelines-controller pod in the tekton-pipelines namespace of tools/toolsbeta k8s cluster is down or can't be reached.

The procedures in this runbook require admin permissions to complete.

Error / Incident

This usually comes in the form of an alert in alertmanager.

There you will get which project (tools, toolsbeta, ...) is the one it's failing for.


The first most likely step is to ssh to tools/toolsbeta (depending on the project the alert is from) cloudcontrol servers (i.e toolsbeta-test-k8s-control-4.toolsbeta.eqiad1.wikimedia.cloud). From there you can:

toolsbeta-test-k8s-control-4:/# sudo -i
root@ttoolsbeta-test-k8s-control-4:/# kubectl get pods -n tekton-pipelines
NAME                                           READY   STATUS    RESTARTS   AGE
tekton-pipelines-controller-5c78ddd49b-dj4hz   1/1     Running   0          34d
tekton-pipelines-webhook-5d899cc8c-zwf7p       1/1     Running   0          34d
  • You can also check the log of the pod's deployment with kubectl logs deploy/tekton-pipelines-controller -n tekton-pipelines.
  • It might also make sense to check if there has been any recent code change and re-deployment attempts. Again a good place to start is by looking at the recent commits in https://github.com/toolforge/buildservice
