Jenkins X builds fail with "The node was low on resource: [DiskPressure]."
Let's approach this from the Kubernetes side. There are few things you could do to fix this:
- As mentioned by @Vasily check what is causing disk pressure on nodes. You may also need to check logs from:
kubeclt logs: kube-scheduler events logsjournalctl -u kubelet: kubelet logs/var/log/kube-scheduler.log
More about why those logs below.
Check your Eviction Thresholds. Adjust Kubelet and Kube-Scheduler configuration if needed. See what is happening with both of them (logs mentioned earlier might be useful now). More info can be found here
Check if you got a correctly running Horizontal Pod Autoscaler:
kubectl get hpaYou can use standard kubectl commands to setup and manage your HPA.Finally, the volume related errors that you receive indicates that we might have problem with PVC and/or PV. Make sure you have your volume in the same zone as node. If you want to mount the volume to a specific container make sure it is not exclusively attached to another one. More info can be found here and here
I did not test it myself because more info is needed in order to reproduce the whole scenario but I hope that above suggestion will be useful.
Please let me know if that helped.
